Rog strix 4090 core/hot spot

[va02stephen]

Not sure why I have seen such a rise in temps I only purchased this card just over 1 month ago

These results are same test, same fan speed, same room temp basically nothing has changed

originally 2 weeks ago
60-65c core
70-75c hotspot
86c memory

Over the last few days
65-70c core
90-100c hot spot
76-80c memory

I can’t understand how the temps have risen in such a short space of time but somehow the memory has decreased

in my opinion, and assuming that you have not change settings on gpu, it could be from one of this: system overclocked(cpu or ram) generating more heat or the dust filter needs to be checked...

I have already checked all that and I don’t overclock literally everything is as it was originally

There's such a thing as thermal pumping which affects very high power GPUs. The thermal interface material essentialy gets pushed out by the difference in thermal expansion between the GPU silicon and the copper heatsink.

Did you buy the GPU new? If so consider to return it, or just live with it.
If you bought it 2nd hand then you might have to re-paste.

Hotspot temps normally vary from about 7-15 degrees more than core.

The fact you’ve had nearly 30c difference points to a contact issue.

Perhaps a manufacturing issue. You could try and fix it yourself but if it was me I’d want it sorted by the retailer depending how good their customer service is.

But if you’re comfortable taking the card apart it would be a quicker fix doing it yourself.

I just don’t think you should have to on a card that’s a month old. Would be different after a year or so.

This is absolutely normal for those cards, read tons of reports about this. Thermal paste is most likely pumped out (bad factory application) + heatsink not making good contact.

Either get a replacement or repaste with PTM7950 (super easy, no need to repaste again) and you'll see a world of difference.

Hello!
Are you ready to accept this?
If your card is under warranty, you should try to get it back.
I have the same problem with Asus Strix RTX 4090 OC, Hot Spot reaches 93°C, at the same time, the case is well ventilated, the room is 24.5°C.

For around a month now the card in question has had PTM7950 on the core and now even at near 500w the core does not exceed 56-58c and the hotspot is around 64c-66c, if I was you I literally wouldn’t even bother doing a RMA for it just order some PTM7950, asus rma is terrible either they will reject it because it’s still within spec or from what I have seen online you will get some beat up recon in return

I am sincerely glad that you have solved your problem. But the thing is that my video card is under warranty, I bought it a month ago, I tried to take it for testing to the official service center of this store, but they did not even report in what conditions they tested it, in the test report only information that the maximum temperature is 80°C, and what exactly is not clear. I am very much annoyed with such work of these specialists, at least get a job there and do everything correctly yourself. It's disgusting!
I apologize, I'm just very upset because I bought the card for $2500 USD.

I understand but as I said before the warranty won’t cover this as it is still within spec unfortunately so there is little to nothing they will or can do, I do agree it is annoying and frustrating as a card of this price/build quality certainly shouldn’t be like this! The problem is they could send it to asus but asus would reject it and send it back, the only option you have is to keep using it the way it is…. Or to apply PTM

Unfortunately in terms of thermal performance the variance between GPUs coming off the manufacturer line is ridiculous and is why "temperature limits" are set so high by manufacturers. Its much cheaper for them to gaurantee your GPU will run under 110c than it is to gaurantee it will run under 60c, even though both are possible from the same GPU model depending on the quality of how it was assembled

Couldn’t agree more with this, I have seen some strix out the box not break 60c and other run mid 70s, but as far as a repaste goes PTM is amazing stuff
