RTX 3090 FE Heat

[TechyBen]

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.

350w is often peak, not sustained. Also a "powervirus" app that loads all parts of the GPU may use more power than a full "load" on gaming or benchmarking.

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.

Sometimes you can set the power target/budget with the cards/manufactures software. For example on my AMD CPU I can set the wattage target down from 125w to 100w etc. For the ASUS 1060 GPU I have, I can downclock it or set it to "power save mode", though in testing it only makes a difference of about 20w on my version, but that's about 10-20% anyhow as I cannot get the entire system to draw more than 290w.

As others have said, although I don't have a 3000 series, is that the VRAM run hot on these cards. If you can cool the VRAM that sometimes helps. But opening a window is also a good option.

Granted, things like Furmark give an unrealistic power use.
Stock my card would sit around 350W~ when gaming, as long as load was near 100%. Which CoD BoCW would do.
Undervolted to 850mv playing CP2077 still hits 300W~ most of the time.

The 3090 has been reported to draw around 400 Watts to give perspective or more, the op I quoted said he shouldn't have to limit frames which tells me he plays with uncapped frames.

And it's also about how the pc is generating heat into the room, not just a part reporting high temperatures, it's about heat being dumped into the room.

The better your cooling solution the more efficiently heat will be dumped into the room also. The only solution is to either turn down FPS or buy another card which uses less power.

Nice. Still amazed the new cards (top of the stack anyhow) can draw more than my entire system overclocked, and that's WITH the 5800x. XD

Yep. My bad. I keep forgetting the 3090s can push that high. Still use to cards (us mere mortals can get hold of) not drawing more than 150w or so.

Just buy a portable air con unit for the summer months or alternatively you can game in your underwear

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.

I can get mine up to 102 after a few hours of use with the stock power and fan curves at 4k 60 with RTX on. Load in the 70s to flat out. GPU fans stay at <50% with the case fans at about 1100 so it's bearable noise wise. I'm not going to mod it.

Small room, PC sucking 500w and a 43" HDR monitor does mean it gets quite warm. The cats seem to like it.

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?

Yes. Its a small nuclear reactor but everyone knows this. I have to leave the window open behind mine or the corner of the room turns into a sweatbox, its worse at night as teh curtains are quite efficient at blocking cool air flow.. If I could swap for a 6900XT I probably would there were none available when it was bought so there you go.

I've got it power limited at 91% it prevents the worst of it the fans drive me nuts otherwise and I've +163 +287 on the clocks.

I've gone through the process of modifying my 3090fe with several different thermal pads and pastes, wouldn't recommend it it does yield interesting results but not worth the effort.

I've found that the program you use affects the result very significantly, for instance a loop of firestike extreme for 30mins while limiting clocks to 1830 power will top out at 330w draw and so GPU core will peak only just over 60c with the hotspot about 12c above that and memory at 86c peak
Quake 2 rtx seems to be the worst I've found, even clock limited it will pull the full 400w after 30 mins, GPU will probably be more like 68c peak with hotspot 13c above that and memory flirting with 100c in the current weather.

Which pads and pastes did you use?

I used thermalight odyssey and mx5. No change in gpu temp after new paste around 66c to 71c while gaming. For memory before was 90c to 104c, now max memory temp at 84c.

I haven't try rtx games yet but will check it out when I have time

Thermalright oddesy and gelid extreme, 1.5mm on both. I had margin of error results between them, once I realised how to compress them properly while fixing the back plate on. It was a 15c drop from the standard pads for me, I saw q2rtx hit the 110c limit in testing with default pads.

I had big issues with thermal pumping on the GPU, so much heat in a small area was causing new paste to be pushed out after a few days impacting temps by 10c or more. In the end I had to use conduconaut, really didn't want to but couldn't find another solution that would definitely work long term.
