# Why Does My Laptop Fan Get Loud When CPU Usage Looks Low?

My laptop fan sometimes ramps up during light work, even when Task Manager shows low CPU usage. It happens most often after waking the machine from sleep, but I haven’t found one app that consistently triggers it.

Could something besides processor load be causing this, such as background updates, a blocked vent, or a sensor reading? If you’ve tracked down a similar low CPU usage fan problem, what did you check first?
