That doesnt sound too bad for a laptop. I once ran my gpu up to 100c because i forgot to turn up the fan setting prior to gaming, and im on a desktop. I found that out when I suddenly heard the cooloing fan going to high speed in short spikes. So if you are really worried about it then try turing up the fans a little before gaming, assuming that you have not already tried that.
I think the fans start automaticlly when the temps rise, cuz when you just surf around or working on the laptop you don't really hear him at all and the temps are then around 45-50° max, everything
When you start to game you hear the fans kick in.
But what I noticed is that when I play WoW i get max temps of 65-67° for my cpu's and my GPU, but when I play NFS Undercover (the newest NFS) i get spikes of 77° on my cpu's and GPU
Last night I got artifacts on my NFS while my gpu was 70 or so....
Really weird..
