Get the Dust Out!

Withing Folding@home running at full power, my computer is fully utilized all the time.  This morning, I checked Speccy and was shocked to see that both my CPU and GPU were running at unsafe temperatures. Later, I blew out the computer with compressed air.  After setting it back up, I ran Speccy with FAH again. The temperature went down about 5 degrees Celsius, back into the upper areas of the safe temperature zone.  So, I recommend you frequently take off your computer's cover and get all the dust out of the fans. It's also a good idea to make sure that the fans are spinning easily.
