Hi i've bought less than a month ago an Acer Aspire 7 A715-51G-52MV. I've this issue where the cpu speed is always unstable and the temps go crazy starts at 40*C and with minimum usage, even in idle they start going up and down even till 70°. I tought i had a defective model, and i got it replaced, but even the new one has the same issue. I think the problem is in the cpu because or some power management thing because the only way i managed to get the temps and the core of the cpu stable was by disabling turbo boost with throttleStop. What can i do, i can't work with the fan on 100% speed cause it reach 70° every minute.
