7900 XTX hotspot temp?

[Blindsay]

I thought I remembered an issue a while back with the 7900 XTX hot spot temp? I can't remember what happened with it though. I ask because as I'm sitting here playing Diablo 4 I see my hotspot at 108c. Everything bone stock and plenty of airflow (in fact I just got a new case to try to help it a bit even)

It was an issue with the AMD-made reference cards, they didn't fill the vapor chamber correctly so the cards weren't being cooled correctly. If you have an AIB version, this isn't a factor.

That's high, but not crazy high. Those cards with issues would be pinned at 115C, not 108.

Thanks, It is this exact card - https://pg.asrock.com/Graphics-Card/AMD/Radeon RX 7900 XTX Phantom Gaming 24GB OC/index.asp

I had it in a Fractal torrent nano but it couldnt get fresh air that well. Just put it in a phanteks NV5 but that didnt seem to help much

i mean, just hypothetically, that could happen to any manufacturer,  it was just a more widespread issue with the reference cards? And i also remember something about "cracking" which I'm not sure was the same or another issue? (or even another gpu entirely)

IIRC, it was mainly reference design cards as even AMD acknowledged the problem that a small portion of 7900XTX cards were affected. 

 

For the latter with silicon cracking, I believe it was mined RX 6800XT/6900XT 'Big Navi' dies cracking as the miners stored them improperly and when buyers received them, did not allow for them to get acclimated to the temperature inside their homes causing them to crack.

ah, i see, thanks (so a different card)

well as said,  hypothetically that could happen to anyone with a vapor chamber,  but then im not sure how bad 108c really is... maybe hotspot isnt even the important factor, just sounds *really* hot to me (max hotspot for my 3070 would be around 80c as it never seems to deviate more than 10c from "gpu temp")

No problem!

No doubt about that as anything can happen across other card models as well as manufacturing defects can never be theoretically zero, and some will have issues. However, with that being said, it was a bigger issue for initial batches of reference design cards with a bad vapor chamber.

It's a bit on the high side but throttle point should be 110C (where it will start down clocking).  I have a 7900 XTX Taichi (so beefier cooler) and it is generally sitting between 90 - 100C with 70% fan speed in Diablo 4 when framerate was uncapped for reference.  There are others who have been getting temps better than mine as well, but even after a re-paste that's where it ended up.

EDIT - Saw the concern about comparison between edge and hot spot temps.  With my 90 - 100C it never got about 70C.  I had a 3080 previously and was concerned with the large hot spot delta as well.  Still not super happy with a 30 degree delta there, but after going through the effort of repasting myself I couldn't see it getting any better

Different card architectures are different. According to @Livin the throttle point for current gen cards is 110C, on my Radeon VII it was 115C. VRAM can also get quite spicy, I believe some Ampere cards run it at a steady 110C for ages and it's good up to 115C. Both are different from the main core temp itself, and them being much hotter than you'd expect isn't necessarily cause for concern.

I wanted to add some input here because I've had experience with hotspot delta on my 7900XT which is the basic amd reference design.

 

I bought the card maybe 4-5 months ago and was having 30-40c hotspot delta from the start.

 

I would regularly see 95-100c on the hotspot while my GPU Edge temp was sitting at 65-70c.

 

My card was bought used from a UK company called CEX but with a 2 year warranty.

 

I did however have experience repasting GPU's and knew there was nothing scary about it so I bought myself some TFX and went at it , It was super viscous and supposed to be pump out resistant.

 

Ended up getting good results....but not really.

 

I would bring the hotspot down to the 80s but after 2-3 weeks it would climb up to 95-100c again....I would open the card and all the paste was gone from the middle of the die....Pump out effect at work.

 

Tried a few difference pastes until I read about Honeywell PTM7950 which is not a paste but a phase change pad that claims to be nearly impossible to pump out.

 

So i bought it , Little bit more finicky but honestly still not too hard to apply and I'm pleased to say that 3 months later my GPU Edge temp is 65c and my hotspot is at 81c

 

It actually has gotten slightly better over time which is apparently quite common with it.

 

That's with a reference card and a maxed out power slider so really the worst case scenario.

 

So all you guys who have high temps on your 7900 series,  Get yourself some honeywell and ill expect to see results posted in here!

My card's on RMA right now for other reasons but will definitely be checking that out after it's back.  16 degree delta on hot spot is way more reasonable than the 30 degrees I was seeing.

Interested in this PTM7950 since my Strix 3080 has some serious pump out issues. It seems to be difficult to find a reputable seller. Can you send a link to the website you used to buy it?

Just to clarify this a bit, GDDR6x is what's good for 115C. GDDR6 will throttle before that.

So i found in the AMD software the max speed of my gpu fan was set to something like 76%. I gave it a max of 100% and it is able to keep the hot spot at like 98c max now

Did you try to UV?

I know the threads older, but thought I'd post a quick update/note surrounding the conversation on hot spot.  Through various events, I ended up getting credit for my 7900 XTX Taichi and have swapped it for a Sapphire 7900 XTX Nitro.  Hot spot on the Nitro is waaaaaaaaaay better.  Now I'm getting a 10 - 13 degree delta between edge temp and hot spot with a max hot spot temp of 84C. 

 

Don't know what was happening specifically with the Taichi card, but for a similar size cooler the Nitro is performing much closer to what my expectations were.  Keep in mind, I did disassemble the Taichi and repaste, still ending up with a 30 degree delta....

I have the Nitro version of the 7900xtx as well, and my Hotspot Temps never went above the mid 80s even during a powervirus workload like Furmark. I assume Sapphire just gets better contact with the entirety of the GPU die compared to the Asrock models, though we'd need to see testing to know for sure.

100 C hotspot temps seems way too high to me.   I've noticed the Asrock gpus get a lot of complaints/reports of high temps.

For anyone reading in the future:

I ended up buying it from here. It arrived to Ireland in 34 days. Seems to be working well on my Strix 3080. Did a 450W OC torture test, and it leveled out at 78 degrees average and 95 hotspot. Time will tell if it sorts the pump out issue.
