The four pictures above show what we can do to keep your system running at peak performance.
Dust can build up underneath the CPU (processor) fan, causing less air flow through the cooling fins on the CPU heat sink. This can cause the CPU to run at a higher temperature then recommended, which can cause it to run less efficiently or even possibly shut down! The main system board (motherboard) can also be affected by the excess heat.
