The four cores of my Alienware M14x run at about 60 degrees Celsius when the computer is started. After playing a big game like Battlefield 3 for about 20 minutes, the computer starts overheating with the fan speeding up audibly and the game starting to lag. This is so disappointing and depressing that I have started to abandon the expensive machine. My room is cool and the computer rests on a working Cooler Master. I can't find any virus with Malwarebytes or Avast Anti-Virus Pro. Any ideas on what I could try to avoid the overheating? Are there perhaps more than one fan inside, with only the one visible through the bottom panel (on the left) switching on?
