RTX 3090 FE Heat

[RayRayFPS]

Hi All

I've been having to open windows/put fan on next to me to not melt with the amount of hot air blown out the side of my 3090 card.

It's usually when playing prolonged periods of warzone for example.

Temps from gpu stay between 60-65 degrees which I'm sure is fine.. However when you put your hand out to feel the amount of hot air being pushed through it's quite incredible.

I'm in a fairly decent size room with decent ventilation but even so.. I can't believe how quickly it heats up the room.

Does anyone else find this?

Majority of the heat will be coming from the memory on the back of the card. My room stays at a constant 21c while gaming but my card is watercooled so its like having a radiator on at all times.

It's a 350W card. It outputs 350W of heat at 100% load, this is by design.

You could undervolt to lower heat a little if you like, though it's not going to be significant.

 

[feck199]

I used the undervolt method, so far been running at 2025 at .943.

Kinda rushed it so likely could improve it, but it’s been stable past few days abs some long sessions on warzone.


55gpu temp and 82 on memory. Pulling around 200w based on gpu-z during warzone. For testing or benchmark I still see it pulling upwards of 400w.

*Correction, those temps were from a benchmark pulling 385w & 80% fan. Expect during gaming were less.

Majority of the 350W power budget (also heat budget) comes from the GPU core. The VRAM does run hot (unless you do thermal pad mod), though still isn't the main source of heat.

I dunno about that haha, the backplate on my watercooled card is hot enough to cook an egg , but you're right majority of the heat is from the core.

Yeah the backplate is hot, though it's due to the fact it doesn't have active cooling, just a metal backplate. Mine got even warmer, once I did the thermal pad mod! Though VRAM temperatures are now 15-20DC cooler than before, so well worth the effort/expense.

Yeah i ended up with 2 92mm fans and small heatsinks on my backplate to further cool it down. Even though the card is watercooled, it was still pretty hot.

My temps now are around 64-66c while gaming in this hot weather, ambient temps are around 20c.

Something does not add up here? Your undervolt is very mild on the volts side, yet your saying you pull just 200w?? That cant be with GPU at 100% load?
Are you limiting framerate in Warzone? Id have thought that would pull near max power.

But to the OPs point, yep room gets very toasty during gaming sessions.
Its another reason Id love to move my PC into the under-stairs cuboard. Get the heat and coil-whine away from where I am sitting.
If I owned the house rather than rent... id have done it already.

The problem with the 3090FE is Nvidia bodged the rear memory thermal pads so it doesn't properly meet with the backplate so no amount of heatsinks/fans on it will do much, you can fix this yourself but at the risk of voiding your warranty/causing RMA issues, this brings memory temps down to ~86C max.

If you want to limit heat during summer, download EVGA Precision X1 and power/temp limit it, be sure to run as admin or settings won't always save properly.

I did comment that during benchmarks it’s closer to 400w. So when the GPU is maxed it’s more.

Warzone doesn’t Max the GPU at all, could be cpu limited but even if I set render to 150% or more I still only see around 60% usage.

3800x @ 1440p. Render at 150% is 4k.

To try and be clear, I read the temps and 385w from a screenshot from a benchmark when posting. I saw 200w draw while playing.

my old r9-390 was the same

when I changed it to a rx5700 the missus started to mention the heat then when I got the rx6700xt she really started moaning about how cold the dining room was

Undervolt and FPS limiter will get heat output down substantially.

Are nvidia aware of this problem, so were saying this gpu cooling aint fit for purpose really, we should not have to undevolt or limit fps to keep it cool should we.

 

[tommoT.Striker]

I think i'll leave mine as is. The memory temps are crazy, mine are up to 98C when gaming, but i'd rather not worry about its warranty status.

The cooler does cool the gpu down quite well but main issue is the memory thermal pads they use aren't good enough, poor heat transfer/not enough contact duo to thickness.

My card memory can go up to 96c while gaming. GPU 69c max. The case is h510 so airflow isn't good.

Undervolt 100% means i can keep my pc in a locked cupboard where majority of all the heat goes into the loft.

My 3090 is far quieter than my MSI Gaming X 3080, Radeon VII, Vega64 Liquid, RX480. Don't think I've had a quieter card to be honest!

 

[Daytrader]

Just replace thermal pads, and job's done. Quiet, cool running card. My 3090 is far quieter than my MSI Gaming X 3080, Radeon VII, Vega64 Liquid, RX480. Don't think I've had a quieter card to be honest!

Thx, but not sure i want to do that, and nvidia should fix this really.

Actually, you can't fix a high wattage GPU from not producing a lot of heat of you are asking it to run at 100% and unlocked frames.

You wanted the power, you got it, this is the consequence, limit the frames to what ever your monitor is or to a reasonable level.
