Hi all,

I've "made" my new pc just few weeks ago with the following specs:
Cpu Ryzen 5 3600
MoBo Asus b550 tuf gaming
RAM 16gb corsair (now i don't remember the model type, but i will...if needed)
Gpu gtx 1060 6gb
Power Supply Corsair 750 w (the same as RAM, if needed)

Ten days (around) ago, i've changed the stock cooler with one from deepcool, 'cause, monitoring the cpu temperature, i saw that was stable over 50degrees, in idle. So, made this change the temperature was lower (39/42 degrees).

Now, since two days, the temperature is going up to 72 degrees, Always in idle.

I tought could be the new cooler failing so i put back the stock one but temperature goes over 80 degrees.

The stragest thing is that if I check the Bios, the temperature are normal (around 49 degrees with stock cooler), while in Windows 10, keep rising the limit.

Latest BIOS, latest driver, no overclock, nothing changed since i've made the PC.

Does anyone have idea?

Sorry for my english, i'm from Italy.

Thanks
