7900XTX temps

[PDifolco]

Got an Asus TUF OC 7900XTX

It's kinda beasty and can easily reach 2750MHz on a 1.1v undervolt, at 420W TBP

But I don't want noisy fans and limit them to 2000rpm...

So in gaming GPU temp goes up to 70C, which is fine (?), but junction/max temp reaches 95-99C, I kinda wonder why, don't recall my 3080 having such difference between average temp and max (maybe cause the chip is different..)

And is this a real issue or just harmlessly hot  ?

Completely harmless. It's also important to note that after certain fan speed it's incredibly deminishing returns. The difference between 65% and 100% fan speed is usually 2-3C. Think about it, you're using a 420W GPU which is equivalent to a RTX 4090 with a smaller cooler. So yeah, normal.

No it should be fine. I think max is 105C on the junction but some say the max is 150C (which can't be right but it should be somewhere in between) so I think it's fine. But as I recall i think your case has a solid panel. I might swap that to a cheap mesh panel one as solid panel cases tend to have at least 5C higher temps than mesh ones

Well max hotspot after 2 hours "hi load gaming" (TWW3 is super demanding on GPU) is 103C

Max TBP is now ... 490W, it's kinda ridiculous  

Max fans 70% just before it's helicopter level 

My case is a P600S, front "cache"  and (glass) side panel removed, but it's enclosed in a kinda "niche" under my desk, plus ambient is 25ish

I have setup a reverse airflow so that air can get out (so front exhaust top and rear intake)

 

Will revert to 2.5GHz clock max, it's max 90C and 350W, at least for this summer. But this card is damn powerful!!

Yeah that cooler's definitely not made for that heatload. I had the same experience with sliding the power to +20% on my PowerColor 6950XT because the cooler was the same as it is on the 6900 XT so it got overwhelmed. Also you should benchmark everything on stock and compare it to +20% power overclock. You'd be shocked how little performance you get for the insane amount of heat/power. I personally got like +4% FPS for an additional 50W (from 340 to 390). It's just not worth it.

Well the cooler is pretty bigger than the one of a 6950XT, the whole card is 34cm long 3.5 slots wide  

And the (average) temp is quite ok, +45C over ambient with 70% fans and overall badly ventilated enclosed case, with nearly 500W power !!

Surprising thing is hotspot at +30C over average temp... I suspect the new RDNA3 to be AMDesque in jumping to high hotspot temps as do their CPUs

Those temps won't harm anything, nothing serious like that.

 

Nah, at worst when the hotspot/junction hits 100°C it will probably force itself to dial back clocks regardless of your OC.

 

You are certainly running a bit warm though, even at absolute max OC the hottest my Red Devil 7900-XTX will go is about 87-88°C on the hotspot with power draw at +15%/430 Watts.

 

I mean I know the Red Devil is one of the best-cooling AIB designs on the market and the TUF is more focused on durability (go figure - name), but I think the TUF is supposed to be a bit better than that.

 

Look up max temps for your specific card on google and see what others are getting out of it. Save your OC profile as you will probably have to revert to default to compare as most review articles won't include OC numbers.

 

It could be as simple as a slightly uneven cooler mount (screws not at even tension) or some weak thermal paste. But I do gotta say your case looks a bit restrictive. I run the LanCool 216. If you take off the side panel and temps drop by a massive amount, then just buy a better case.

 

I too get fed up with the noise when the fans go beyond 2000 RPM so I have my fan curve set up to jump to 58% fan speed at 75°C Hotspot and then its a flat line to stay there until 90°C Hotspot where it then ramps to 75% fan speed and finally 90% fan speed at 100C.

 

58% Fan speed reports an average of 2010-2025 RPM on the tachometer. So because of how I set up the fan curve, my fans are basically at 58% speed at all times during gaming or any GPU-heavy workload for that matter.

 

Of course the Red Devil 7900-XTX is quite the heafty Boi itself, coming in a 338mm long and 3.5 Slots Wide

Max temp I've got is 103C on same conditions than yours (max +15% power, 430W on the GPU itself) and it didn't really clock back, or only very slightly

I suppose the Red Devil has a tad better cooling with the vapor chamber stuff, didn't know that when I bought mine, should have gotten it instead !

Plus my badly ventilated PC and my AIO (meaning less airflow inside the case close to the GPU than with an aircooler, rad is on top) make things even worse

 

I manage fan speed even less agressively than you too, 0 to 40% on low temps, 50% with hotspot from 80C up to 94C (1800ish rpm, still quiet) and max 75% at 100C (2400 ? a tad noisy)

But if I let the BIOS "quiet" mode it's even more conservative, don't think it goes over 50%, it's even hotter and not meant for OC

 

Now I was OCing mostly for fun, and impressed that the card (and my PSU!) can go to up 2800MHz/430W no sweat, and with high but safe temps, as hotspot quickly reaches 100C but stays there

That gives maybe 4% more performance, but I have more than enough without that already... 120FPS vs 110 isn't really noticeable, and I'm locked to my monitor 120Hz in many less demanding games whatever the card settings

I think that during hot months I'd stick to a max 2500/2600MHz clock, 350/380W, temps 64C/85C hotspot, and quiet fans

Hmmm, thats pretty toasty.

 

Well I did update my previous post. Your case does look fairly restrictive, try removing the side panel and then running some stress testing.

 

If it drops by like 10C or more, then you really need a better case.

Huh front and top are mesh, and side panel is already off, but it maybe doesnt' do much as the side is 2cm from the wall  , and I suspect any case will have same issues as long as I don't redesign my custom made desk (should have left some more width ...)

CPU temps are fine tho (with PBO+200 and CO -15 to -30, gaming 65 to 70C, max 80C in Cinebench or such, ambient 25C, 160W PPT), and GPU is only getting that hot on a beefy OC by Summer, can live with  cooler GPU settings

Oh okay that other pic made it look restrictive but I guess I didn't click on the pic to view it full size so it could be cut off.

 

But ya, that desk setup looks a bit tight but as long as the exhaust gets out the back and you aren't recycling that old heat then there shouldn't be any problems.

I have reversed the airflow : on a standard front intake top/rear exhaust hot air wasn't able to escape and stalled in the area.. It's much better with back and top intakes than can suck some fresh air (I added dust filters) and front exhaust that really can send hot air out !

You didn't read all my ramblings neither then (but np )

@PDifolco

 

Since we were talking about it, I decided to play with some new OC settings and I was able to push my hotspot to 95C and might have even broken some sort of record...?

 

IDK but one thing is for sure... Ive never seen a standard air-cooled XTX record a score like this one...

 

What The Hell did I just Do...? LOL
