Hello! Recently I've had some problems with my i5 9400f. I know that the i5 9400f is a turbo boost CPU (base speed 2,9 and boost 4,0) and it changes frequency depending on what task it is performing. Even when I don't have anything on my computer running my CPU is around 3,9 GHz. It hasn't always been like this, before when I did not have anything running it was around 2,0 GHz. I have had the CPU for 2 years and it was this month that it randomly happened. When I play games now too my CPU goes over 90 degrees Celcius when before this had happened it was usually around 70-80. I have no idea what the problem is, I have already hard reset my PC deleting everything off every drive in case it was a virus, but that did not fix anything. If you know anything about this please respond I will appreciate any sort of help!

Hello Otto45
Thank you for posting on the Intel️® communities. The temperatures mentioned are not harmful for the processor, the maximum temperature allowed is 100°C. Intel Turbo Boost Technology is a way to automatically run the processor core faster than the marked frequency (Processor Base Frequency: 2.90 GHz). Once enabled, Intel Turbo Boost Technology works automatically under operating system control, if you don't feel comfortable with the current frequencies you can disable the technology with a switch in the BIOS. No other user-controllable settings to change Intel Turbo Boost Technology operation are available.
