What is Reddit's opinion of CRJ Male Mini 4-Pin GPU Fan to Female 4-Pin PWM All Black Sleeved Adapter Cable?

From 3.5 billion Reddit comments

Reading the other posts and your responses lead me to believe that the PWM functionality on your fans is no longer working.

1. Zero load will enable fan stop, which is why the fans stop spinning.
   
2. No PWM will send 12V straight to the fans, causing them to go full blast.
3. Card under load will cause temps to rise, which means the fans need to go to work. If PWM doesn't work, you still get the full 12V.

At any point, do the fans work at a normal RPM or is it only full on or full off?

Solutions:

1. Check the fan cables. Make sure they are still seated properly and they are not damaged.
2. Test the fans individually. You could use something like this adapter which will allow you to connect a GPU fan to your motherboard. Then use the motherboard to set a fan curve (or use a fan controller software and see if the fan speed adjusts based on your settings).

This is the cable I use: CRJ Male Mini 4-Pin GPU Fan to Female 4-Pin PWM All Black Sleeved Adapter Cable https://www.amazon.com/dp/B07S4L41TN/ref=cm_sw_r_cp_api_glt_fabc_70BJGZ2PAVJXG722WP0P?_encoding=UTF8&psc=1

It plugs into the pump cable inside the kit (albeit upside down so yes you do need to cut a groove on the other side to make it work) and then it plugs into a fan header.

The order for the pinout of both fan connectors is [GND, 5V, TACH, PWM] and will almost always be this for any electronics fan.

An adapter like this should work for you.

I carefully took off the shroud, but i didn't have to repaste the gpu. Because ultimately you can remove the shroud without having to re-assemble the AIO thats attached to the gpu die itself.

I forgot the exact username but its in the evga forums but just search "3080 XC3 Hybrid pump mod in the evga forums.

But ultimately you will need to buy this CRJ Male Mini 4-Pin GPU Fan to... https://www.amazon.com/dp/B07S4L41TN?ref=ppx_pop_mob_ap_share

And then you'll end up plugging the 4-pin wire for the aio pump to that adapter, and then you will connect it to a 4-pin fan header on your mobo or a pwm 4-pin fan controller.

Since you can’t control pump speed on these I highly recommend getting this adapter cable, and using it to hook the pump to your motherboard fan header rather than the gpu header, so you can control pump speed. https://www.amazon.com/gp/product/B07S4L41TN

Sometimes these pumps can make funny noises but even setting them to like 80-90% will clear it up with no performance impact. Below 65% they are completely silent (wouldn’t bother going much lower, at some point it won’t work properly). Personally I keep my pump in silent mode until GPU goes above a certain temperature, then boost back to full speed. My radiator fans are also on motherboard, but the VRM fan is connected to GPU.

Keep original cooler and it’s hardware organized and in good shape, you’ll need to put it back on if you ever have to RMA the card (or if pump craps out, which hopefully won’t happen before you upgrade the card).

honestly, im about to return it
you cannot control the pump speed and it makes this low buzzing sound and its really annoying, only fix is the cable mod https://www.amazon.ca/gp/product/B07S4L41TN
to plug the pump directly into a fan header.
if they let me control the pump without dumping another 30$ into it, i might keep it
not satisfied with the money spent on the product received

Hybrids are quieter under load, but louder when idle (due to pump noise). That’s not to say they’re loud when idle, just not silent like a card with no fans spinning would be. I would say the noise of the pump is comparable to the noise of a 7200rpm hard drive (just the spinning motor noise).

Temperatures are obviously better. My 3090 idles at about 4-5 degrees above ambient. Under load tops out at 60 C but that’s with the radiator fans running quiet, it could be lower if I wanted. In typical games it’s usually mid 40s to mid 50s. I replaced the fans in mine with Noctuas for even less noise, the default fans are okay but basic.

You will get better, more consistent performance because the card won’t have to downclock as much to keep temps in check. My undervolt overclock is much more stable on the hybrid.

The kit is easy to install. It’s the same as an actual hybrid card in the end. So if you can only get a regular card you could always buy the kit.

One mod some people do is to get a mini GPU to 4 pin cable (like this one so they can connect the pump to a motherboard fan header, which will let you control the pump speed. This would require disassembly so it’s easier to do when you’re installing a kit anyway.

The main problem people have with the hybrids is getting bad pump noise. Though often I think this is due to suboptimal radiator placement which can result in air bubbles being stuck in the pump, causing a grinding or chirping noise. And sometimes people are very stubborn about this so they’ll do a bunch of RMAs instead of changing the position. And sometimes it’s just a bad pump.

Yeah, if you want to control the pump speed you need to use this adapter and plug it into a motherboard fan header, then control the speed with that. Lot of people do this to reduce pump noise on the hybrids. You could have pump at a low speed (like 60%) when idle, and only put it to full speed during gaming.

I would get the cable that can control the pump speed on a DC fan control header. Basically you hook up the pump cable reversed on the pump header and plug the other end into your fan controller or motherboard then make sure you set the speed above 60% minimum.

I have already done an RMA for my first kit and had pump sound on the second one as well but the cable fixes the issue. I would install it just to have the option to change pump speed the mod didn’t really mess with temps too much maybe a degree or two higher but still way cooler than the stock heatsync.

FYI Cable can be found here

Seems like this is not a hot issue but for those interested it did end up working. Getting this adapter, bypassing the card's header, and plugging it into a motherboard CHA_FAN header allows you to set the fan speed in the bios to control the pump power. Lowering it to 80% cut the sharpness but going to ~50% made it near silent.

Ended up tweaking a curve so it'll kick up the speed if the system is getting hot. So far it idles at around the same temps ~30-32C and kicks up to ~50-55C under load at 2ghz, max power.

This is what I used: https://www.amazon.com/CRJ-4-Pin-Female-Sleeved-Adapter/dp/B07S4L41TN/ref=pd_lpo_2?pd_rd_i=B07S4L41TN&psc=1

Too late now I guess ¯\_(ツ)_/¯

You can solve your fan noise issue by buying one of these adapters: https://www.amazon.com/gp/product/B07S4L41TN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

That will allow you to plug the fans in to your motherboard fan header, after which you can control it using fan control software that can read the GPU temperature, such as Argus Monitor.

That will only set you back $35 or so between the cable and the license--a lot cheaper than buying a new card. Just offering it up as an alternative option.

Sounds like pump noise. You can't control the pump speed if you installed it per instructions. It will always be at 100%, any RPMs you see is from the fans on the radiator. The only way around this is to use an adapter such as this one and plug the pump into a motherboard fan header so you can control its speed (you basically route the cable out of the card into the mobo, see the extra cable coming out in this pic.

However that noise doesn't sound normal even for regular 100% operation. You may have air bubbles stuck in the pump somewhere. You can try to work them out by gently rocking/tipping your case in all directions while the pump is running, this might free any bubbles. If you have any mechanical hard drives I would unplug those to be safe.

Sometimes people using the cable mod are able to eliminate any weird noises by just reducing the pump speed slightly (which doesn't really affect performance). But if you can't fix you probably have to RMA and get a new pump.

I run my pump at 65% when idle and kick it up to 100% any time the GPU temp gets above 40C. At 100% speed my pump is audible in a quiet room but not objectionable, so probably nothing like what you're hearing.

The pump on that hybrid cooler is noisy because the GPU drives it at 100% RPM.

If you don't mind spending a few bucks and re-opening your cooler (I think you'll have to clean the die and re-paste), you can get a cable like this and connect the pump directly to a motherboard PWM header: https://www.amazon.com/CRJ-4-Pin-Female-Sleeved-Adapter/dp/B07S4L41TN/ref=sr_1_5?dchild=1&keywords=crj+gpu+cable&qid=1627773476&sr=8-5

Then you can set the header type to DC and run it as low as 60-70%, which will make it dramatically more quiet. I don't think this will affect the longevity of the pump, and doesn't seem to have a big impact on cooling performance either.

Looks like what to do about radiator positioning is covered. I just wanted to point out one thing since you mentioned mining - the VRAM cooling on the hybrid kit is a good deal worse than on the FTW air cooler for reasons that should be readily apparent once you get to look at it. Since you’ll have the card apart anyways you’ll probably want to get better thermal pads to help as much as you can: https://www.reddit.com/r/nvidia/comments/n0y6s9/my_experience_with_replacing_thermal_pads_on_the/

Also, the pump always runs at 100%, which can cause audible noise. If you want to change the pump speed, you can get an adapter cable (or cheaper from AliExpress etc) to plug it into your motherboard or fan controller - in this case you would control it with voltage.

Yeah I set it in BIOS for like 80% speed and I haven’t seen it go over 55*.
