    Question B450-F-Gaming CPU Temp sensor

    Hey at all!

    First of all sry for my bad english im from germany 😑 .

    I try to describe my problem.

    Ive bought a mainboard and cpu and so on.

    After i build the system i push power on and go to the uefi and the cpu temp sensor shows me -24
    Degrees celsius! Hmm i think i do a bios uefi update.
    One moment later the temp is even -24 degrees😧.

    So fan control isnt possible with this temp. I started windows 10 install the latest AI-Suite
    And drivers. Okay after restart the same temp.
    After that i install HWinfo and core temp and Ryzenmaster!
    In every program is the cpu temp normal 36-60 degrees celsius.

    So what happened? Are the sensor on the mainboard broken?
    Or is it a software problem?

    I hope anybody can help me😬.

    Thanks a lot.

    This has been brought up before for Ryzen systems and I was under the impression that it was resolved with a BIOS update. Did you update to the most recent BIOS? It's possible the sensor is defective but I'd start with firmware/software updates.
    I'd like to deploy my troops in her country.

    I also have an Asus ROG Strix B450-F Gaming.
    I run a Ryzen 5 2600 (which I can OC to 4 GHZ) with G.Skill Trident Z RGB 32000 RAM @ 3400 MHz.
    I use an Arctic Freezer 33 Esports Edition tower cooler and my CPU idles at around 29-32C.
    My Motherboard and PCH temperatures are ~40-41C @ idle.
