What Windows system do you use?
Did you notice this issue since first day?
In my opinion the CPU could be stressed by an process which is running in the background. This means that the CPU runs at 80-100% and this means that cooling system run faster in order to cool down the CPU.
I think you should start the task manager and should check the running processes.
There you can see the processes which would use a lot of the CPU performance.
Possibly such processes belongs to installed software or tools… so if you don’t know exactly what a single process does, google to get more details about this process.
Easier solution??? Well, it would be interesting to know if fresh OS installation would help to avoid this… I think its worth a check...
