It sounds like something is running up the CPU until it overheats. I would do a scan with malwarebytes anti-malware

Also if you start to hear the fan open Task Manager and click on Processes Tab, then click the CPU column so that the high numbers are at the top. Idle process(doing nothing) should be at the top. If it isn't then whatever is at the top or right under Idle is the one using too much CPU.
