The CPU PCB is filthy. It is covered in dust and grime.
  • The CPU PCB is filthy. It is covered in dust and grime.

  • Dust acts like a blanket that keeps the PCB warm. Hot components are more likely to fail. A hot computer drives its fans hard in an attempt to keep cool, using more current and making noise. The life of the fans is also reduced.

  • This dust is another reason why this computer was having difficulty keeping cool.

  • The PCB and heatsinks, fans, case interior and other components should be cleaned regularly. Later in this Service and Repair Guide you will be shown how to clean this PCB.
