Panasonic Toughbook CF-31 Heat Sink

A heat sink is an attachment for a chip that prevents the chip from overheating. It has a thermal conductor to carry heat away from the central processing unit (CPU) into fins that provide a large surface area for the heat to dissipate throughout the rest of the computer, thus cooling both the heat sink and processor. 

Signs that you need a new Heatsink

Signs from your Toughbook indicate a failing heat sink. Some common indications include:

  • Slowing down the computer, frequent freezes, blue screen of death 
  • Corrupted data 
  • Accumulation of bad sectors 
  • Strange noises (like clicking or whirring sounds) 
  • Overheating computer 

If you notice any of these signs, react immediately to save your files and prevent any data from being lost.
