Cause i noticed, when i play the new Call of Duty : Black Ops, when it starts spinning fast, it doesn't lag, but when it slows down, it massively lags.Any tip on how to keep it always running on max?
what's your laptop model and specs ? this will help giving you a right answer I think your laptop runs @ its max capabilities and thus overheats its fan being not able to cope with all that heat... you should run GPU Z and log temps and fan speed when in game.
come to me with your laptop / and sit in front of the door one and all your problems are solved ok, just kidding install another fan with more speed ~cost around $25
