What is Reddit's opinion of Thermalright Thermal Pad 12.8 W/mK, 85x45x1.5mm, Non Conductive Heat Resistance, Extreme Odyssey Silicone Thermal Pads for PC Laptop Heatsink/GPU/CPU/LED Cooler (1.5mm)?

From 3.5 billion Reddit comments

Yep, the backplate removal is really straight forward, just follow the Gamers Nexus teardown (remove the magnetic half X, remove the screw covers with tape, then remove the 4 screws) and the Crypto At Home teardown.

For the 3090FE I used https://www.amazon.co.uk/dp/B08CGVZ4YG?ref=ppx_pop_mob_ap_share - 2 packs is enough for just the back (although maybe search r/nvidia for other experiences, as well as the cutout guide)

FWIW here's the ones I used. Also I'm not sure if your card has the space between the PCB and the backplate, but if so you would also want to put new thermal pads there as well that correspond to the VRAM locations. That way you can transfer the heat in both direct and passive directions.

I got this one: https://www.amazon.com/nkomax-Thermalright-85x45x1-5mm-Conductive-Temperature/dp/B08CGVZ4YG Are they good? I also saw some videos of people adding heatsink to the back plate of the card. What do you think about that? I’d rather not open the card

Assuming you have both the top and rear as exhaust, I'd say you might have to take apart your 3080FE repaste the gpu die and remove the stock thermal pads and apply better thermal pads.

I did this with my 3090FE and noticed a significantly lower temp results.

i linked the guide above

I used these. Lowered my temps by 15°C.

Hey, did you end up replacing the thermal pads, if so what's the thickness that you used? Any brand in particular? I'm looking at these: One enjoy Thermalright Thermal Pads 12.8 W/mK, 85 x 45 x 1.5 mm, Silicone Thermal Pad for Heatsink/GPU/CPU/LED Cooler which seem to be good. I just don't know if the thickness is ok

Thanks

Hey op I am in a current situation. I have 3 cards I need to repad. How much compound do you like I would need ?

Looking at this

Thermalright Thermal Pad 12.8 W/mK, 85x45x1.5mm, Non Conductive Heat Resistance, Extreme Odyssey Silicone Thermal Pads for PC Laptop Heatsink/GPU/CPU/LED Cooler (1.5mm) https://www.amazon.com/dp/B08CGVZ4YG/ref=cm_sw_r_awdo_4J8A7GC5VX1R9ACJ12NT

I swapped them out with Thermalright 1.5mm and they work much better. Makes full contact. Thermalright Thermal Pad 12.8 W/mK, 85x45x1.5mm, Non Conductive Heat Resistance, Extreme Odyssey Silicone Thermal Pads for PC Laptop Heatsink/GPU/CPU/LED Cooler (1.5mm) https://www.amazon.com/dp/B08CGVZ4YG/ref=cm_sw_r_cp_api_glt_i_EZT0KPPG5NJ6SBNHBV0P?_encoding=UTF8&psc=1

You can buy them from various sites, Taobao and Amazon does appear to have Thermalright Odyssey's available, do check for positive reviews!

The cheap non-branded thermal pads can be purchased readily almost anywhere online

I do not recommend removing the metal plate until you have your thermal pads ready, as underneath the metal plate has multiple blobs of fluffy (probably degraded I presume) thermal pads

For anyone reading this in the future, I was able to drop the temp to a steady 90c while pushing the GPU to 123 MH/s simply by replacing the thermal pads on the backplate with these bad boys: https://www.amazon.ca/gp/product/B08CGVZ4YG/ref=ppx\_yo\_dt\_b\_asin\_title\_o01\_s00?ie=UTF8&psc=1

Ah sucks about the fan pcb, depending on how bad its broken, you could prob fix it. Yeah I think thats the better option honestly. Also upgrade the thermal pads, the one on the FE are awful. I haven't done it to mine yet but these are the ones people use. Its mildly sketch to put heatsinks on just thermal pads, any knock to your pc and a heatsink could come off and short something internally. People who have done this in the past use thermal adhesive, but I would only do that if this is your END solution, because it might be impossible to remove the thermal epoxy.

I used these:

I believe you just need the 1.5mm and 1mm. I also just used some old artic mx-5 paste I had laying around, better than nothing that is there.

There are a couple of reddit threads that walk you through the process and where you should place the pads/paste.

Thermalright thermal pads

Here is the link to the 1.5mm thickness ones, but get the proper thickness pads as per the instructions to the backplate.

Hey! I can't give exact specifics as I've only done it for a 1070 sc and 1080ti, but I saw about 15°c drop in temps using:

https://www.amazon.com/dp/B08CGVZ4YG/ref=cm_sw_r_apan_glt_fabc_QGCCVRJTKDTHNZXMYPY2?_encoding=UTF8&psc=1

I got a pack of 1.5mm and a pack of 2mm. I used the 2mm to replace everything on the front of the pcb between the mounting plate and 1.5 where needed between the cooler and plate. Can't remember if I did anything on the backside of the card. I believe I left stock pads on the backplate (if there were any). As a disclaimer, I also applied grizzly kryonaut on the gpu die and this may have also helped with temps.

I'm a tinkerer on a budget, and will say I've heard amazing things about gelid's extreme thermal pads. The gelid ultimate I've heard is a bit too stiff and make getting good contact difficult, but the extreme are supposed to have a nice cushion with great cooling ability.

If you're redoing the pads, may as well get some good paste to go with it.

Best of luck!!

If you have any other questions I'll help as best as I can

I was just asking about the thermal pads. I was thinking about using thermal paste, but I was a bit worried about a gap issue. I noticed you mentioned to get ThermalRight because it's high quality. Looking on Amazon is this one the right one to get?

https://www.amazon.com/nkomax-Thermalright-85x45x1-5mm-Conductive-Temperature/dp/B08CGVZ4YG/ref=sr\_1\_3?crid=A9U219JK8VWB&dchild=1&keywords=thermal+pads+1.5mm&qid=1630623266&sprefix=thermal+pads+%2Caps%2C228&sr=8-3

oh i used Thermalright. Got from Amazon.com: Thermalright Thermal Pad 12.8 W/mK, 85x45x1.5mm, Non Conductive Heat Resistance High Temperature Resistance, Silicone Thermal Pads for Laptop Heatsink/GPU/CPU/LED Cooler (1.5mm): Computers & Accessories .

I used size 1.5mm because it worked for the youtuber with the same 3080 Vision model. I would try googling to see if anyones done a thermal replacement for what model you may have to see what size you may need.

You will throttle at 110. 104 is fine but still a bit warm for gaming. You need 1.5mm pads. I purchased these: https://smile.amazon.com/gp/product/B08CGVZ4YG/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

You can get away with 3 packs of them if you cut correctly but I was paranoid and bought 4 just to be safe.

Thermalright 1.5mm You will need at least 3 packs to repad the entire card. Less if you're only doing the backplate and more if you waste a lot cutting.

Awesome stuff!

Think I'm just gonna suck it up and give it a go if I break it I'll RMA it lul...

What size pads you get for the front?

I've ordered 1.5mm for the back I think they're quite sturdy ones so they don't squash much.

Here's a link - Thermalright Thermal Pad 12.8 W/mK, 85x45x1.5mm

These are the pads, just make sure you get the right thickness:

You may not get as good an improvement depending on the brand of the GPU. I have a mate who did this also but his GPU vram temp sits at 96C, which is still a decent improvement though

Can't help with Amazon links. My Thermalright TFX Came from Nan's Gaming Gear, and others from China (Aliexpress) and I bought the clone Thermagic ZF-EX also.

Pads were https://www.amazon.com/gp/product/B08CGVZ4YG/ but they don't have the 2mm versions (I'm using 2mm on the backplate side only).

I used these, 12.8 https://www.amazon.com/dp/B08CGVZ4YG/ref=cm_sw_r_cp_apa_fabc_598925XG62H4P69V7PBN?_encoding=UTF8&psc=1

When I opened up the GPU side, I reapplied the thermal paste but left everything else the same. Somehow I keep making everything worse. Now my memory temp is at 108/110, with fan 100% and memory down to 750.

How is this possible?? It's killing me. Backside stock pads were tiny and gross, I replaced that with better pads and a lot more of them, and reapplied the thermal paste to the core. And everything is just worse? What am I doing wrong here?

https://www.amazon.ca/Thermalright-85x45x1mm-Conductive-Resistance-Temperature/dp/B08CGVZ4YG/ref=mp_s_a_1_2_sspa?dchild=1&keywords=thermal%2Bpad&qid=1609170475&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzNlNKWlU5RUNEWVE...

2mm/3mm is too thick. Your cooler isn't making good contact with the GPU die. Use these instead. I did them on my FE and achieved desire results.

https://www.amazon.com/dp/B08CGVZ4YG/

I purchased:

• 2x packs of Thermalright Thermal Pad 12.8 W/mK 1.5mm - https://www.amazon.co.uk/gp/product/B08CGVZ4YG/
• 2x packs of Thermalright Thermal Pad 12.8 W/mK 1.0mm - https://www.amazon.co.uk/gp/product/B08CGL7MLN/
• 1x Noctua NT-H1 3.5g thermal paste - https://www.amazon.co.uk/gp/product/B002CQU14A/

I mainly use my 3080 for gaming but for fun on the side I mine with it too when I am working for example.

This is my temperatures since I kicked off the miner this morning. Average of 87.8C with a max of 92C. Hottest I managed to get them to go was about 95C when I turned the fan speed right down. It barely breaks a sweat playing games now, the fans don't even spin up too much. I replaced all the pads on the cooler side and added pads to the missing VRAM on the backplate.

I used this YouTube video for sizes etc.

https://www.youtube.com/watch?v=fSF-9W2PVec

First of all the things I used were as follows: 4 Thermalright 1.5mm Thermal Pads from amazon: https://www.amazon.com/dp/B08CGVZ4YG?ref=ppx_pop_mob_ap_share 1 Thermalright TFX Thermal Paste from amazon: https://www.amazon.com/dp/B08CGPD9RN?ref=ppx_pop_mob_ap_share And MAKE SURE you have the right tools! This is the most important part. Disassembly requires many different screw tips. I used an IFixIt kit. Also, when you get the the little led cable, take your time, be super careful. It took me a long time and many tries to pull the little cable out. Good luck to anyone who attempts this. It was very stressful especially because of the price of the card and how difficult they are to come buy. Only do it if you know what you are doing and PLAN AHEAD!

if thats a 3080 or 3090 you need 3 of these https://www.amazon.co.uk/gp/product/B08CGVZ4YG/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 thermal pads to replace the 1s in your card apparently it will knock 25c off the temps :) gonna refit mine RTX MSI SUPRIM 3090 on sunday see if it helpshttps://www.tomshardware.com/uk/news/replacing-geforce-rtx-3090-thermal-pads-improves-temps-by-25c?fbclid=IwAR3IjHl0lknINQgWVdwclh-61DdV7-LkCGRwhSwTMyljRFp426r2RTriEX4

The 460xx drivers are unstable for a lot of people.

Well while we're here, why don't we start from the basics?

Drain the loop and put the stock cooler back on. The thermal pads are still intact, right?

If the pads are damaged and you need to replace them, you can use Thermalright odyssey 1.5mm pads on BOTH sides of the card, GPU VRAM side, VRM side, and backplate VRM And hotspot sides. I have pictures of the exact spots to be padded.

Backplate and hotspots:

Two different backplate and hotspot mods (from hardwareluxx dutch forum).

GPU side is obvious (no need to add any extra pads on the GPU core side).

I thought the same thing until after I did it. Watch the YouTube videos from Max Tech and Created Tech. They explain it all.

However, the MacBook Pro 14" has a better display, so if you need/want that it's worth it to get the 14" Pro. But I don't need that better display when using my Air remotely. It's good enough. I use it docked with a 5K2K LG display so that point is moot.

Here are the links to the exact thermal pads you'll need, from Amazon US:

Thermal pads are awesome

I've used these when I did my thorough cleaning. 1.5mm.

https://www.amazon.com/gp/product/B08CGVZ4YG/ref=ppx\_yo\_dt\_b\_asin\_title\_o01\_s00?ie=UTF8&th=1
I added 64gb of ram which the computer booted and a ssd
It only stopped when i which the gpu memory vram paste

I found a how to online then bought pads and followed a YouTube vid.

I have a MSI 3090 Suprim X

Thermal right 1.5mm pads found here thermalright

https://www.amazon.com/nkomax-Thermalright-85x45x1-5mm-Conductive-Temperature/dp/B08CGVZ4YG
Those were recommended to me for my 3090 FE. I used 4 packs and a couple guides to make it all work. Dropped temps about 35C

I used these the first time : https://www.amazon.com/gp/product/B08CGVZ4YG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

The second time I used : https://www.amazon.com/gp/product/B0999N175L/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

Right now since winter is coming it has been getting more cool. As of now it hovers from 92-102 C but it's never gotten to the mid to high 80's and stayed there like everyone else's. I have to keep it at 74% power to get 103mh/s and under 102c memory junction temps. I really do not like this card and wish I had sold it once I got it from my pre-built.

Yeah this specific combination of gpu and block was difficult. I just remember messing around with different pad thicknesses. I bought 3 different thickness pads: 1mm, 1.5mm, and 2mm from Thermalright

https://www.amazon.com/gp/product/B08CGVZ4YG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I honestly don't exactly remember which ones I used on the VRM's and rear RAM though. I want to say that the VRM's have 1mm, front RAM 1.5mm, BUT 2mm on the rear RAM. Sorry that I don't quite remember.

The screws that I used were M2x10mm

https://www.amazon.com/gp/product/B07LGWJ9LJ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

the screws that came with the block were M2x9.5mm and struggled to grab the thread. the 0.5mm length helped a ton and were really nice screws.

Let me know what you decide to do and if you have more questions, I'd be glad to help out.

i just took the backplate off my MSI 3090 Suprim X and replaced the thermal padding with some of this > https://www.amazon.co.uk/One-enjoy-Thermalright-85x45x1-5mm-Temperature/dp/B08CGVZ4YG?pd_rd_w=a5wfc&pf_rd_p=b2f9603e-9a6f-4e3b-a877-9d7289604c4e&pf_rd_r=CBTN5DT86ZHYASNCXC06&pd_rd_r=ba13025e-92e2-4cc2-a3d2-ff9fb825e1d2&pd_rd_wg=rgP6I&pd_rd_i=B08CGVZ4YG&psc=1&ref_=pd_bap_d_rp_1_t

used 3 packs of 1.5mm and doubled up the thickness cos i couldnt get 3mm. but when i did it i just took the backplate off and didnt go deeper into the card so it didnt touch the warrenty sticker :)

brought my temps down from 110c to 92-96c when over clocked (-300 +1200) it hits about 100c .. and 125MH/s still but not 110c like before.. so if you getting them temps anyhow it should go less with some decent thermal padding..

Can't comment on the EVGA model but I have an MSI ventus 3090 oc (it's really not the best 3090 by a longshot) in my gaming rig and fitted the bykski active backplate + front block. It came with these really soft blue pads (no brand) and the temps were awful. Mining, memory junc ~86c+

I ended up splitting the card / blocks again and fitting these:

https://www.amazon.co.uk/gp/product/B08CGVZ4YG/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

Difference was clear. Memory junc temps dropped to 66-70c.

I'm using these and the stock heatsink of my ASUS board.

Thanks for the very detailed overview!

So I have a RTX 3090 FE. I used Thermalright 1.5mm pads on both sides: https://www.amazon.com/gp/product/B08CGVZ4YG

Great pictures! Yah that's a TON more paste than the CPU takes LOL.

I did research and Arctic Silver is still holding up as one of the top thermal pastes, however I'll take your recommendation and order some Thermalright TF8. I'll have it by Saturday. So I'll be sure to spatula it good like the pictures show (I noticed your pictures aren't of a 3090 FE -- what card is that?).

Will there be an issue with me opening it back up again just to redo the paste? I assume after a few days the thermal pads will be well nested and re-seat just fine?

https://www.amazon.com/dp/B08CGVZ4YG/ref=cm_sw_r_cp_apa_glt_fabc_ZVJCPTSG94FMNAW7SFMF?_encoding=UTF8&psc=1

https://www.amazon.com/gp/product/B08CGVZ4YG/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1

This where the ones

I used three packs of these:

https://www.amazon.com/gp/product/B08CGVZ4YG/

I've heard from multiple places that 3 of these ThermalRight Odyssey 1.5x85x45 will do just fine. You don't need 6.

In any case, I bought that and this ThermalRight TF8 paste, and have both on me already. I'm going to do it this weekend, and I can reply back later on how I do.

(And to confirm, yes, I'm doing it on a 3090 FE. Oh, and I guess you will need six if you're doing it on two 3090 FEs.)

They are 1.5 Thermalright on both sides: https://www.amazon.com/gp/product/B08CGVZ4YG/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

TF8 on the chip: https://www.amazon.com/gp/product/B07K442WXV/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

There wasn't a plan to the size of the pads. Just trying to follow what I saw in this thread. Went bigger than smaller. Almost ran out at the end. The net is 100 mh/s at 80 degrees junction and 45 GPU as ETH seems like a good stress test. I was at 50 mh/s at 80 degrees before. We are only as good as our sensors here. My guess is there are a lot of FE owners out there that cooked their cards mining ETH on the standard power curve or the "Safe" suggestion from mining sites. My pads were awful looking when I opened it up. Must have been a Friday.

https://imgur.com/gallery/8dOoZ82

Good news. The heat sink still works because that back plate is still smokin hot.

https://imgur.com/gallery/zgIDNdO

Yikes. I think someone asked this exact question several weeks ago, but I don't remember the reply. There was also something asked about 2080 FE as well.

But I think it was a combination of 0.5mm and 1mm thermal pads. If you don't know for sure, you should buy both. Get the used card first (they are hard enough to find), buy some Thermalright Odyssey 0.5mm and 1mm thermal pads here.

https://www.amazon.com/gp/product/B08CGVZ4YG/

Then measure the original pads with a calipers. There should be VRAM, VRM and sometimes "inductor" pads. the inductor (aka 'choke') pads aren't really there for cooling, more likely there for balancing (they don't hurt). Then you'll be fine.

If you measure 1.5mm on anything, then you can stack a 1mm and 0.5mm. Unopened pads last forever, so it's not a bad idea to buy more than one set of each--it's better to have too many pads than to run out during a repaste/repad!!

I would order two sets of each pad. Do not underestimate how small the pad package size is. 85mm * 45mm isn't a lot of pad. The amazon picture is obviously completely out of scale--the pad is obviously much smaller than the packaging! The only decently sized packages are 120mm x 120mm, but you can only apparently get those from China (Aliexpress), from the slow boat (Yao Yue Shop).

Note :DO NOT buy from this seller:

https://www.amazon.com/Thermalright-Thermal-Conductive-Silicone-120x120x2-0mm/dp/B08PY4J2F3/

While these are the ideal size (nice big squares), these pads only cost $15 to $20 on Yao Yue Shop on Aliexpress, and this amazon seller is also shipping from China too, so complete total scam.

Good job on not getting scalped.

The 3090 FE is a very reliable card. Especially considering how many eVGA FTW3's are dying with the red PCIE light of death (just check their forums), I've only seen three reports of dead 3090/3080 FE's...One was DOA, one died after some time and another had a non spinning fan (this was caused by an assembly problem--the PCB actually damaged the fan's ribbon cable because the cable wasn't routed through its crevice.

You may possibly need a thermal pad re-pad job of the backplate, to deal with hotspot and VRAM related temp issues in the future, if you get crashes going past +200 mhz on the VRAM, you definitely need a pad re-work. This is actually surprisingly easy to do, as you don't even have to get access to the core side to do it. All you have to do is remove the backplate (the hardest part is using sticky tape to remove the magnetic torx screw covers!), then you pry the "V" bracket off with your fingers, mini philips head on the four first screws, and Torx T5 on the second four screws and off it goes.

For the re-pad job, just buy Thermalright Odyssey 1.5mm thermal pads (these are the best pads you can buy for the price, and can survive a few re-mounts, unlike the Fujipoly 17 w/mk pads), buy two packs of these (THREE if you want to re-pad the GPU side also)

https://www.amazon.com/gp/product/B08CGVZ4YG/

And then remove all of the existing stock pads, and apply 1.5mm pads to the VRAM and hotspot areas as shown in these two screenshots (two slightly different repads--both using all 1.5mm pads).

https://i.imgur.com/ttF7Nla.jpg

https://i.imgur.com/Jx4IuqL.png

1.5mm pads also work for the GPU side VRAM and VRM strips as well :)

They allow my shunt modded 3090 FE to survive 80C GPU torture hell at 600W TDP without thermal throttling (didn't win the GDDR6X lottery however so +600 mhz max on VRAM, for gaming, +650 for benchmarking, +500 for daily).

Disassembly guide: bookmark this for the future.

I took pictures of the proper thermal pad locations for replacing them. You also need to add a few extras (per igor's suggestions).

First, if you tear any pads, you need to replace them with new 1.5mm pads. Some of the original pads are 1.0mm and some are super compressed 2mm pads, so 1.5mm pads will contact everything.

Arctic 145x145 1.5mm pads will work for this and you get a nice big square, but there are pads with better thermal conductivity, like fujipoly 11 w/mk pads, but the size of the pad is completely highway robbery atrocious. One 60x50mm is barely enough to do one side of the video card. There are also these:

Here is a picture of the hotspots of the 3080 FE card. The 3090 is the same, except there will be RAM in places where you can't pad on igor's picture, but the hotspot by the "V" is the same.

Here is a picture of my (almost) completed pad replacement, along with the painted shunts visible as well (the little grey thin rectangles), two on the left, one on the right (if you make the pic horizontal). Three more on the backside, they say "005" on them.

This last picture was taken from a 3090 off Igor's page, but missing the bottom left "V", that, when flipped, would be top left "V" on the PCB. This is igor's pic, not my pic.

This hotspot is shown on the 3080 image here. Not sure why Nvidia did not put a pad there on the 3090.

I circled in red where to move the pads to or where to add a pad. My backplate is shown next to it flipped the other way. Make sure you do not put a pad over the shunt resistor(s). Just leave a gap around the shunt.

The heatsink side picture is rather easy. Just make sure if you are replacing pads, use 1.5mm pads. (igor's picture).

Any decent modern 1000W+ PSU or greater will work. I highly suggest using an official 12 pin cable. When modding a card like this, you want as little dirty power or voltage drop as possible and your pad work and thermal paste should be top tier, if you're going to be using air cooling!

With painted shunts, with the MG chemicals silver paint I linked, the card will draw about 525W at 114% TDP estimated, so it will be reporting around 23% reduced power in HWinfo64. You can use a "1.33x multiplier" for changing the power reporting to compensate.

I suggest using a toothpick when painting and bridging the shunts. And take your time. Wood is a great material for working with paint like this since it will stick to the wood easily (just don't have too much on the toothpick), then use the tip and slowly paint over the shunt.

This is good stuff. Be careful it is toxic.
