The fan on the Dell GX620 computer is designed to pull the heat away from the central processing unit (CPU) to keep the processor cooled down so it can work properly. If the fan wears out or gets damaged, it can cause the system to slow down or overheat, creating more problems for the computer. The GX620 fan is attached to the motherboard with plastic clips and is secured with locking levers on the sides. Tips Warnings Writer Bio
