The build-up of heat from the "central processing unit" (CPU) in a Toshiba Satellite laptop can cause performance problems. The CPU fan is vitally important in regulating the heat generated by the CPU as it performs large and complex calculations to carry out a computer user's commands. If the cooling effect from the CPU fan is minimal, then the processor may slow down. Toshiba Satellite laptops that use the Windows 7 operating system have functionality that allows users to increase the speed of the fan before the processor has a chance to throttle back.
