What test(s) are you running?
CPU utilization is controlled automatically by/within WIndows....you might try selecting (within Windows power plan) High Performance to see if that allows elevated temps before any throttling occurs.....; otheriwse, Balanced works fine for moany folks...
Most laptops do not have the thermal capacity for any sort of extended stress tests, so, I'd avoid them, as they will likely hasten any thermal throttling if that is occurring....
