Hello ,

I have a question regarding the temps of the RX7900XTX cards.
I have recently bought the Powercolor RX7900XTX Red Devil but I wonder about the temps I get.
I never had a AMD GPU before.
In idle the junction temp gets to 59°C with the fans at 0 rpm.
Whilst gaming the junction temp gets up to 99-100°C with the fans at +/- 1150 rpm.
I use the GPU and Adrenalin software out of the box, no tweaking or overclocking of anykind, all settings standard.
When I rev up the fans to 1400 rpm (this is the max rpm I find tolerant of sound) the temp drops to around 95°C.
Are these normal temps?

You can NOT trust your hands for this.
I have a chimney setup, that if I put my hands underneath it, I feel air blowing on them, even though I know those fans down there are intakes. If I place a napkin underneath, I can see it getting pulled upwards.
What you are feeling is [credit goes to Karadjgne for this quote]:
"Fans work by the blades movement creating a low pressure area in front of them. Faster the rotation, stronger the vacuum. The byproduct is a pressure wave out of the back of the fan.
With that, exhaust fans work by creating a low pressure area, and nature abhors a vacuum, so the higher pressure air supplied at the front of the case will...

Those temp values don't seem normal to me. Idle TEMP is also high. Is there proper air-flow inside your ATX cabinet ? Provide full PC specs. Which PSU model are you having ?

Even though AMD can claim those temp values are normal, but in reality they are not normal. But since you have a CUSTOM AIB model from Powercolor, the temps should not cross that limit. There have been known issues with the "reference MBA" AMD cards though, and no known issue with any custom GPU model yet.

It does appear that only reference and AMD-manufactured Radeon RX 7900 XTX GPUs sold by AMD and its partners are affected. Aftermarket cards featuring custom cooler designs seem to be safe, so your particular GPU should not behave in a similar fashion. Unless it's an MBA card, which I doubt.

I mean, AMD's reputation was tarnished by reports of some Radeon RX 7900 XTX reference graphics cards experiencing thermal issues involving GPU hotspot temperatures, or the maximum temperature read by the sensor, reaching as high as 110C.

AMD initially said 110C is the normal junction temperature, which is why it refused some buyers' RMA requests and advised those users who are experiencing unexpected thermal throttling to contact AMD support.

A recent investigation by Roman 'der8auer' Hartung led to the overclocker placing the blame for the overheating issues on the Radeon RX 7900 XTX's vapor chamber; it's believed that some batches of the cards lack sufficient fluid levels.

While the Radeon RX 7900 Series desktop GPUs can operate up to 110 degree Celsius when under heavy loads (such as 4K gaming), doing so for extended periods of time isn’t recommended for the health of the GPU.

No, not by a mile.

RX 7900 XTX should never surpass 70C under full load.

GPU temperatures remained below 70C in all of our testing, with fan speeds south of 2,000 RPM. The fan speed and temperature results also line up with what we experienced in regular use, as the XTX card has a larger and more potent cooling subsystem and often runs noticeably quieter than the XT model.

Brand new or used/refurbished? 🤔

Normal for this gpu. Did you research this before purchasing? It their high end gpupushed to the limit.

Issues are with some reference GPUs, but OP has PowerColor version, not the AMD reference version. So, this doesn't apply to OP.

Can you list your specs to include the pc case?

Many reviewers test gpu's in open test benches and do not reflect actual temps when the gpu is in a the pc case.

First of all thanks for the responses

Case: Sharkoon REV300
CPU: Intel I7-13700KF
Corsair iCUE H150i RGB PRO XT
Asrock Z790 PG Sonic
Corsair VENGEANCE DDR5 32GB (2x16GB) 5200MHz C40
Corsair HX1000i

I bought the card new on Amazon.de

The temps are reached while gaming (BF2042 on the highest resolution and all settings on ultra).

The front fans are intake.
Top fan is intake, I'll turn this one around to try this as an outtake.
The fans on the radiator blow air out.

It would appear we can take the case out of the equation.

What else does that leave?

Would MSI AfterBurner be a good tool to see the gpu's operating volatges under load? If operating within spec it would lead you to believe a possible issue with the cooler/contact to the gpu itself?

It's a new gpu and if it runs hotter than it should, then I would return it for a new one.

No...
For reference:
iu

You currently have:
-front intake
-rear intake
-top exhaust
Where the heck is the XTX's exhaust supposed to go, if not trapped in the middle of that sandwich?
The rear should be exhaust. The top need not be changed.

The 3 fans from the AIO are blowing the air from inside the case thru the radiator to the outside, so they are exhaust.

Houston, I think something strange is going on, because the AIO fans in the picture you provided are not in the exhaust position. I'm not the only one who would see this being the case.
The other posters seem to have missed this detail of the image, or haven't been back since their last post.
To my knowledge, Corsair has not made reverse flow fans.
This AIO is exhausting out of the case:

This one is drawing air into the case:

I can't follow anymore. What are trying to tell here. I can feel that the rear fans are blowing the air outside the case.

In your picture the 3 fans on the left and the 3 fans on the right are currently set up as intake, the top fan I can't see at that angle.

The reason we know? The bracket for the fan itself tells you what direction the airflow is moving. The exhaust side of the fan is the one with the bracket that extends from the outer fan frame to the center that holds the center of the fan in place. The intake side of the fan has no frame supports.

The fans on your radiator are dumping all that heat into the case. In conjunction with the three intake fans you have serious positive pressure that one little exhaust fan cannot overcome.

Turn the radiator fans around to exhaust and your gpu temp problems should be solved. That case should have great airflow when set up properly.

We are just trying to help you.

With that, exhaust fans work by creating a low pressure area, and nature abhors a vacuum, so the higher pressure air supplied at the front of the case will physically move to fill the void created. That's airflow."

But since those AIO fans are intakes, the vacuum zone is at the back of the case, not inside it. You're feeling that filling of the void.


In case the above wasn't enough English: Flip the AIO fans around so the gpu exhaust has somewhere to actually go.
