Overheating 7900XTX

[stixx]

Hi all, I have a problem with my Sapphire Nitro+ 7900XTX and hotspot temps. I can easily hit 110 degrees on the hotspot while the rest of the GPU stays around mid-60s. This is with an undervolt/overclock/watercooling. The system is running hot as I need to get more radiator space, but I dont think that will solve the hotspot problem. I am using a Bykski waterblock that I installed myself (not my first GPU waterblock install).

Anyone else experiencing this issue? Will Evetech RMA the card if I send it back? I got the card off Carb but it is less than a year old.

Edit: My workaround currently is to turn off some of the graphical features like RT. It brings the temps down 10/15 degrees but very annoying that I cannot use the full performance of the card due to hotspot temps.

Edit2: I have also seen many people recommend graphene pads specifically Honeywell PTM7950. Anyone have experience with these and know where to get them locally?

So is your gpu throttling?

...Evetech RMA...

Good luck with that.

Yeah, I heard not so great things about Evetech but thought it good to ask.

It does throttle down from what I have seen the card do. Runs around 2500MHz instead of 3000. AMD's clocks tend to fluctuate a lot but I expect an average close to 3000.

The 7900 XTX has some sort of weird issue with its hotspot thermal density. The initial reference card had a very good cooler design, but the hotspot for some reason requires a lot of effective heat transfer. I personally found that having my reference card horizontal helped substantially. I'd be interested to know what happens to your temps if you change your card's orientation.

Most individuals online state that the AIB models have regular hotspot temps, but this post proves to me that the issue lies somewhat within the architecture. Would honestly not be a bad idea for you to post this to overclock.net as well to raise awareness.

I have seen alot of online threads about the cooler working better in horizontal than vertical mount, but I have a waterblock installed so it has nothing to do with the cooler at this point. Card is vertical mounted though. Changing orientation will be a nightmare with hard tubing

The reason I think it's an issue with the heat transfer is because there isn't any logical reason why hotspot should fly up. Even at a driver level, I can't make sense of it. It's just a bit odd that that 110c magical ceiling seems to occur to so many XTX cards.

Before you made the above card into a Watercooled version, did you test the card first beforehand? to check temps, boost and baseline of performance?

My 2c here @stixx

Get the card booked into GPUWorx for a thorough diagnosis. It could be a main phase controller on the PCB misbehaving. AFAIK their assessments are free. They are in Villeria, not far from you.

mmm really very unlikely that, that is the case here. If the VRM controller was misbehaving you'd be running into VRM overheating issues maybe or weird behavior that isn't linked to temps of the GPU core.

Still if you're near GPUWorx could be worth it to have someone who gets paid to repair things to look at it.

Does hot spot refer specifically to the die only? Could it not also possibly include the VRM? I've tried looking it up before but couldn't find a definitive answer.

From everything I've seen it is only on the die. Most cards don't even have temp sensors in the VRM. Although technically the SPSs most use have some functionality just doesn't isn't reported outside of the engineering labs.

Hot spot indicates the most thermally dense region on the silicon. It basically reports the highest sensor value on the die. From an interview with an Intel engineer I watched, there apparently a bunch of sensors all over the die. I honestly do not know how they make this shit.

I just played a game of cs2 and my xfx 7900xt hotspot is 102C.
gpu temp 58

Note sure why your hotspot is that high, here is my card at max load with power limit to max of 500 watts

Hotspot not touching higher than 85 to 90 max
Core stable at 60 ish

Yeah I dont know man, there's definitely an issue.
I've arranged to drop it off today with Wootware.

Very weird Obie, wonder whats happening there `(*>﹏<*)′

there's possibly a design issue in the GPU causing temps to spike, or we are hitting limits on how small we can make transistors and have decent temperatures. There are a lot of XTX cards having this hotspot issue.

I only tested that the card was working, did not test for temps etc.

Can confirm I had similar results to @ApocalypesNinja, I never got it over 90.

I do however have very good case airflow, 3xML120PRO in, 3xML140PRO exhaust.

I need some advice, I am hoping that someone on here may be able to help me with this one. So I finally got around to getting that GPU upgrade and decided on the 7900XT. Installed it late yesterday afternoon (did do a DDU), fired up Cyberpunk 2077 and did some tuning. I immediately noticed...

didn't know we had such repair people here in ZA. Thanks! will look at them if I cant solve the issue in a different way.

How did you arrange this? I want to do the same and get a replacement card

Also have a good airflow case, Antec NX800 Tempered Glass Case | 6 x Corsair Magnetic Levitation Series ML140 Fans

3x ML140 Fans intake, 2 x ML140 Fans exhaust above thought AIO and 1 x ML140 Fan exhaust back

Checks ladies XFX 7900 XTX and her core temps are 62, Hotspot is 92 and power pull is 550 watts more than mine still within good temps

Here is my fan curve settings for GPU

AMD cards likes air, better the air flow the better the thermals i have noticed

That's true. The initial assumption was that this was due to cooler design. My reference card ran so regularly when vertical that it's somewhat alarming. I guess in OP's situation, it would be a bit of a schlep to test my theory.
