How to make 3090FE quieter?

RipGroove said:
My 3090FE seems to have a bit of a mind of its own, it sits around 68°C while gaming, sometimes the fan is quiet but sometimes it's super loud even though the temp is the same, sometimes it'll be 68°C and quiet but sometimes even after shutting the game down and the GPU is cooling down it's still super loud.

I'm used to having AIO GPUs where I connect the rad fans to the motherboard so I have more control over the fab curves and overall noise levels and temps but with this FE card is there any way I can control the fans?

I made mine quiet by putting it under water

Check your VRAM (memory)temperatures. This is exposed in GPU-Z and other monitoring programs. The fans are reacting to the VRAM speed, so that's why you hear it spin up to 1500+ RPM and get loud, when the GPU core is at 50 or 60DC. The 3090FE is a great cooler, but has terrible thermal pads out of the box.

My 3090FE was the same - I'd get over 100DC VRAM temperatures when gaming at 4K, which caused silly noise levels, while GPU sitting cold on 60DC.

I replaced my thermal pads & repasted GPU (followed this mostly, but used gelid extreme on GPU side and Thermalright odyssey on the backplate - https://www.youtube.com/watch?v=g3NTHGuNSbY).

Result now is that my memory temps don't go above 85DC no matter what I do, and the card is 100% silent fan wise.

Before I got my card, I was reluctant to do this from a warranty perspective. After researching it thoroughly, I've found several examples where people in the UK have successfully RMA'd a card that's had it's pad changed without any issue, so felt safe doing this. Also was annoying me that such a great cooler design was let down by crappy pads.

Might be worth doing then if I plan to keep it, thanks.

The difference is night and day. It's how the card should be out of the box, predictable noise levels and above all, simply very, very quiet. Just make sure you've got the torx bits, isopropyl alcohol, a fine tweezers for the LED cable and good thermal paste for GPU's (I used SYY-157, upon recommendation by @Falkentyne ) and set aside a good hour and a half and you'll be fine.

Will do, thanks.

Do you know if the 3090fe suffers from this same problem ?
 
I had the opposite problem not so much GPU making a racket but rather the CPU the root cause of all this of course is the sheer amount of heat the 3090 is generating my cpu was being spit roasted sitting above it and the air would build up in the case and the case and cpu fans were going nuts trying to keep on top of it had to fit an AIO water cooler on it and front mount the rad, it needs to be undervolted to stop it getting out of control though the gpu is a small kiln in the case

I'm probably better off with the CPU rad front mounted then, the heat from the GPU can go straight up out of the top exhaust fans.

I'd reckon your issue is the vram temps, the thermal pads aren't the best and when the vram gets hot the fans get loud.The fans seem to really spin up at 70 core or 102 vram. If you run hwinfo in the background it'll tell you what your max temps and fan speed were during a session.

I had problems keeping mine quiet, it'd slowly heat up over the course of an hour or so until everything in the case was getting too hot. I swapped the case fans and messed about with speeds and it still got too hot over time. It turned out I wasn't getting enough air in the case even with all the inlet and exhaust fans I had. Taking the glass panel out of the front cured it.

You can keep a 3090FE quiet with the stock thermal pads, even overclocked but you need to move some air through the case. I ended up with-
3ML 140s in the front with just a filter in front of them. 1 ML 140 in the back and a 360 AIO in the roof with noctua industrial fans for the CPU. The 3090FE is on the stock fan curve, the AIO is on a curve depending on CPU temp which tops out at 1200rpm. The case fans are on curves controlled by Argus monitor depending on gpu core, vram and cpu temp. The case fan curves top out at 1500rpm but they never get over 1300 in use. I use the PC for rendering as well as gaming so I can see higher load on the cpu or gpu depending on what I'm doing.

I can still get the vram to 102 while rendering but the card stays quiet enough. Gaming is typically 60s on the core and 90s on the vram even after a few hours of something demanding and I can't hear the system over my speakers.

I'll definitely check the VRAM temps then. I have 2 ML140's up front but they are pulling through a rad so the air entering the interior has been warmed up by that. I have another 2 ML140's at the top for exhausts and another ML140 at the rear as another exhaust. This case was chosen when I had AIO's on both CPU and GPU so pulling warm air in simply didn't matter too much, the PC was silent under load with decent temps. Ideally with an AIO CPU and air cooled GPU I'd stick the CPU rad at the top and have fans at the front bringing cold air in for the GPU but the rad won't fit at the top as it will foul on my RAM. Currently after playing with the fan curves of GPU, CPU rad fans and chassis fans I've got the noise down to almost silent at idle and a not too distracting level under load but the cost of that is 74°C on the GPU and 65-68°C on the CPU, it like it cooler and a bit quieter but I don't think that will happen with the way the case is setup at the minute.
 
I assume it's Memory Junction Temperature that I'm looking at in HWiNFO?

If so I just ran a Unigine Heaven benchmark and saw a max temp of 106°C (95.5°C average)

For reference the actual GPU temp was 74°C max (66.3°C average) with an average GPU Core voltage of 0.886V

Yeah once you hot 104 the fans go mental and you start to lose performance.

My case is actually setup for an AIO GPU so the newly installed air cooled GPU has hot air blowing on it from the CPU AIO radiator currently so that needs sorting as well, that should help keep the GPU cooler and thus quieter. I'll do that today.

CPU are better being air cooled witha large heatsink and large 140mm fans. Pointless buying an aio as you are just pushing hot air over the GPU and other more important components that require airflow like the vrm, etc unless you use it as an exhaust and then you don't really get the benefits of having one as it's using hot air to cool it.

I've thought about AIO but honestly a decent case with decent airflow and decent fans is always better.

Custom water-cooling is completely different but it's also circa £500 to do properly which makes it completely terrible value for money unless you really need silence or are running a £1k CPU and £3k GPU.

Well the AIO did work fine for me with my last build but like I said I had AIO on GPU as well so it wasn't too much of an issue. With the air cooled GPU I now have it could cause issues.
