i have a 8600m gt on my laptop. using Nvidia system monitor, it says that my GPU is 75 degrees C during normal use (spreadsheet, word processing etc). with coolermaster cooler, it goes down to 65. during gaming of more than 2 hours, the laptop reboots or the games start to sloooow down. my GPU temp goes to the 90's. i know this isn't normal as i read in the forums that people with same GPU, even the overclocked once, go to only 50+ temp during gaming. i wanna know what i can do or if there is anything thati can do. thanks for any help.
