Sounds like your CPU is getting too hot or the system thinks so
("can't turn cooling device on").  I'd check both, that is 
- the temperature of your CPU (Is the fan running? Is the CPU hot?
  Maybe your BIOS can tell you the CPU temperature) and 
- if the cables to the fan control are connected correctly (polarity).
