What is Reddit's opinion of Awxlumv Aluminum Large Heat Sink Gpu Low Profile Heatsink Cooler Fin Cooling 150 x 93 x15mm for HDD 3090 3080 Backplate Motherboard Cooling?

From 3.5 billion Reddit comments

He probably bought something similar to this one and just cut it down to size, https://www.amazon.com/dp/B089QJQY17/ref=sspa\_dk\_detail\_4?psc=1&pd\_rd\_i=B089QJQY17&pd\_rd\_w=2IduT&pf\_rd\_p=54ed5474-54a8-4c7f-a88a-45f748d18166&pd\_rd\_wg=fuY6S&pf\_rd\_r=QMGXEVNYQA487Y89VE6Z&pd\_rd\_r=7e9c4612-f1e5-...

I just tried using extra thermal pads from the batch I got for the VRAM and cut pieces over the backplate matching the spots where the memory modules were then put the massive heatsink I had over the top of them with a 92mm noctua fan on top and I am holding 96 degrees on memory at +1000MHz

Should I cut the middle man and just put the heatsink directly over the memory module thermal pads? Or do you think the extra surface area of the backplate helps?

I did something similar (albeit with a smaller heatsink, with addition of thermal pads) to my 3080 Highest Mem temp when from 102-105F to 90-95F
Not a huge drop, but also I do not direct airflow on the back of the card.
I used this: https://www.amazon.com/gp/product/B089QJQY17

I did at first, no change whatsoever. Then I got this heatsink. Took a bit longer for hit ~94-96c. Then I added a couple leftover strips of 2mm thermalright pads, that dropped things most significantly. I have some .5mm gelid pads on the way to really cover the entire heatsink/vram area and get the best temps I possibly can. Probably still going to crack the card open and make sure I didn't miss a pad first because my Junction temps are wildly worse than anyone else's on the entire internet it seems. (90-94c with fan in pull, current heatsink and thermal pads, mining with power % at 67, all after replacing all thermal pads with the recommended 2mm stuff following guides)

No. I'm contemplating opening it back up just to check if I really did miss something. In the meantime, I bought this heatsink and just laid it on top with a 120mm fan pulling. That reduced temps by a very minimal amount. I added some left over thermal pads and that gave me a steady 90c (67% power target during mining). I have some new pads on the way to really cover the full base of the heatsink and get the best temps possible. I'm just going to have to settle with 2-1080tis-worth of mining performance at 235w to ensure the safety of my Unobtanium video card. There are worse problems to have.

I wish. At this point, I'm surprised there isn't some small company who is machining a drop-in replacement with heatsinks and a fan mount.

I'm using this heatsink with this fan pulling air upwards with some thermal pads underneath.

0.5mm thermalright odyssey pads, sticks pretty good. https://www.amazon.com/gp/product/B089QJQY17/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Hey OP, my 2cents, DONT use k5 pro on gddr6x. It is okay for lower temp applications but it has very poor thermal conductivity which is not suited for more extreme applications. I did a repad+repaste and my core temp and vram temp only went down a little. If you really want to cool your vram, I did an “active cooled” backplate mod and it reduced my vram temp under load by about 10c!

I put thermal pads on the back of my pcb, directly across from where the vram is, so that the backplate could act as a heatsink. I then put thermal paste on the backplate and used this heatsink and just squished it on the backplate, letting gravity do the work (this won’t work for a vertically mounted gpu, but you can prob zip tie it or something). Then I put a 92mm fan on top of that (taped it in place) and that was it.

This is a pic of the final result although I did end up flipping the fan around, as it was rubbing on the heatsink in the pictured orientation.

Depends on the backplate somewhat. If it is flat with minimal cutouts, then these work well, https://www.amazon.com/dp/B089QJQY17/ref=cm_sw_r_apan_glt_i_2RV807KKZTQJRWM0T7Z3?_encoding=UTF8&psc=1

Otherwise these smaller heatsinks are a better choice, https://www.amazon.com/dp/B08Z3671ZN/ref=cm_sw_r_apan_glt_i_XWESR7QNSPC9BCXJH0F7?_encoding=UTF8&psc=1

None of them will help much without a fan.

Oh also I got another 4c off my vram temps by doing an active cooled backplate mod.

I stuck this heatsink on my backplate with some thermal paste https://smile.amazon.com/dp/B089QJQY17/ref=cm_sw_r_cp_api_glt_i_J0CZEWQZ0EB2S42E0GQT?_encoding=UTF8&psc=1

Then I strapped a 92mm fan to the heatsink with some scotch tape lol. https://imgur.com/a/VEzMFVp

I’d suggest mounting your fan the opposite way I did though. The blade was rubbing on the heatsink in this orientation.

Of course this only works with the gpu slotted directly into the mobo. If your gpu is vertically mounted you’re going to need more than just thermal paste and gravity to keep the heat sink on the backplate.

No, here's mine. Kinda ghetto,

Just did this procedure last night on my 3090fe. 1.5mm odyssey pads. gooped on the noctua nt-h2. zip tied this monstrosity to the top of the card with a 120x120mm 1.5 odyssey pad cut to size. ( https://www.amazon.com/gp/product/B089QJQY17 )

I've only tried shadow of the tomb raider and forza horizon 5 so far since putting the card back in, but the hot spot reading only gets to about 72, memory to 70, and the gpu is at a nice and balmy 60c. (gpu-z) No overclocking, pretty much stock on power, etc.

I did add a custom fan curve using msi afterburner so the fan is running at 78% right now, but that's very tolerable.

The card idles about at 30c now. It's a tad insane.

I don't have a fan officially directed at the GPU heatsink I added to the backplate, but the AIO radiator above it is intake, and the rear case fan above and to the left is exhausting at 1500rpm.

sure can.

Heatsink and thermal pad

I could probably buy a higher end thermal pad but this was an experiment.
How it looks on the FTW3. yeah I know it's dusty, I live in the desert.

Not really. I have gone back inside the card to ensure I put a pad on every little spot, and I did actually miss one, but correcting that made no difference. I now have a large heatsink sitting on top of two Gelid thermal pads, with a slim Noctua sitting on top.

I'm not actually sure that the .5mm pads were the right choice, as I can't see if they allow the heatsink to clear the raised metal parts of the card...

Long story short, putting a heatsink on the back combined with undervolting keeps things well under control for gaming. With mining (which I'm not really doing much of anymore) I do still have to use a 67% power target like always.

That's about what I get. I don't mine. I only ran a mining benchmark for like 5 minutes and got to 98C at 100% fan speed. Your temps are fine if you're using the stock backplate.

The problem is the backplate can't release the heat it's absorbing.

Have you noticed that when you stop mining, your VRAM cools down slower than it did with stock pads? That's because the backplate absorbed more heat with the re-pad.

At this point you need to find a way to actively cool the backplate. Depending on your motherboard and case layout or if you have a PCIE x1/x4 soundcard between the CPU and video card, you may need to do one of those heatsink ghetto mods, like with something like this (you'll need more thermal pads obviously, but something like 0.5mm is suitable) and a fan to dissipate heat through the fins.

Asus ROG Strix 3090 at 120.3 MH/s with memory overclocked by 1150MHz, but the memory junction is bouncing between 102-104°C so I stopped pushing it.

Going to attempt to put a 150x93x15mm heatsink on the backplate with a double sided adhesive, 1.5mm, thermal pad. Is the double sided adhesive the best way to attach the heat sink; I'm at bit to nervous to teardown the card just yet.
