I have a Dell laptop with a i7 720QM CPU, and for the past few months the fan has been running nonstop (or so it seems). This hasn't always been the case, and it just started all of the sudden. I finally checked the CPU temperature today, and it looks to me the CPU is running hot (see screenshot below)
I've checked Task Manager, and I don't see any processes that are using CPU excessively, and I've scanned the computer for malware. The computer was purchased in June 2010. What is causing this issue?
