On first gen Ryzen, CPU temps are reported incorrectly on 6.7.4 #1228

Open BlueGoliath opened 8 months ago

BlueGoliath commented 8 months ago

On first gen Ryzen(1800X), CPU temps are reported 20 degrees higher than they should be. This may not sound like an issue as first-generation Ryzen CPUs have a 20-degree offset, but it's not what MangoHud reported before.

Strangely, CPU-X reports the correct temps. Maybe MangoHud should switch to whatever CPU-X is using?

Can you identify which sensor mangohud is using through sensors ?

I think it's Tctl here:

Tctl:         +49.2°C  
Tdie:         +29.2°C

Looking at the code it should be using Tdie as long as we can find it, otherwise use Tctl. Clearly from your sensors output both should be present, so it should work. A possible work around could be to install zenpower
