Are you having any other issues with your PC or just the temp readout?

Just temp readout.If i set CPU fan on auto in BIOS , CPU fan spins on very low speeds and im getting high temps

Sounds like a faulty temperature sensor.

You will have to use a fixed fan speed or use a different sensor to control the CPU fan with software like fan control:

Do you know maybe where that sensor is? Is it on motherboard or CPU itself?
