Nvidia RTX 5080 - Incorrect GPU Hotspot temp, Missing 3rd fan speed, summary info

[Vazulik]

Hello,

I am getting some incorrect values reading in HWiNFO 64 v8.20-5640.

Specifications:
GPU: MSI GeForce RTX 5080 16G VENTUS 3X OC
Driver: 572.16 - Release: Jan 30, 2025 (GeForce Game Ready Driver)

Sensors page:
GPU Hotspot temperature shows 255 °C.
There is not 3rd GPU fan speed reading.

Summary page
Shows instant GPU clocks at HWiNFO startup instead of "datasheet nominal" value. (I am not sure if it is intended and it might not be an error).

Apart from this I do not register any other incorrect readings.

RTX 50 series don't provide Hotspot temperature, it was removed in later HWiNFO builds.

NVIDIA has removed "Hot Spot" sensor data from GeForce RTX 50 GPUs - VideoCardz.com

GPU-Z won’t show hot spot temperature for RTX 5090 NVIDIA has decided to disable the sensor entirely. Performance aside, there are other interesting topics arising from today’s review coverage of RTX 5090 cards. NVIDIA has spoken a lot about its new dual-slot cooler design, which is intended to...

Actual clock values are shown in the Summary window or in sensors.

Ah OK, I didnt know about that.
And do you know if is possible to get info from 3rd fan somehow?

BTW: I am not sure if summary works like it supposed to, because it only get current values on summary window open (its not updated, see my second screenshot).
Its not nominal base values you find in manufacturer GPU datasheet (gpu unit clock, video unit clock, graphics memory clock).

Is there any software able to read the 3rd fan speed? It might be spinning the same as the 2nd one.
The main window doesn't update values during run time. Use the sensors or summary window for that.

I got the same problem on my Zotac 5080 Solid. The 3 fan got telemetry (rotation/temp) in all my dashboards. (Zotac Icestorm/Corsair Icuelink/ Temu-internal Display). The temp is set to 255°. I will reset the card on mainboard, but didn't think thats the problem. The gpu is working well and the 3.fan rotate as the 2 others. Looking for a easy workaround.
