    First I hope that this thread wont be commented as an off topic...

    I had some troubles with heat (even when using cooling pad)...
    More or less thanks to very hot weather and a bit high room temperature...

    So I decided to try reducing heat...

    Since I have dedicated GPU, I know it was producing a lots of heat...
    And AMD Turion X2 also...

    And I found that undervolting will help...

    My temps were very high - according to HWmonitor CPU went up to 80C and GPU up to 94C while gaming....

    SO I did some tweaks on voltage...

    I decreased CPU voltage by 0,15V - from 1,15 to 1,00 V (I couldnt go lower because I got blue screen at 0,975 V when started a game).I used RMclock for this.
    And GPU voltage was decreased by 0,2V - from 1,1 to 0,9 V (GPU couldnt go lower in bios edit). I used nibitor for editing bios (since it is the only way to change voltage on GPU) and nvflash for flashing GPU bios...

    Since then I had no stability issues... And temps decreased dramatically: cpu to 67C max and gpu to 68 after an almost hour of playing gta liberty City stories...
    When playing without cooling pad, temp differs in about 3-5 C...

    And of course CPU is Turion X2 TL-60 2.0GHz and GPU is nvidia 9650M GT from Asus...

    Hope someone will find this useful...

    yes your advice helped me tremendously! I have a Gateway FX p7805u and the geforce 9800m gts would get as hot as 90c, but after I flashed the bios with NVTurboflash I got the temp down to 74c after an hour of gaming!

    Arminator can you give me a screenshot of your RMclock settings?

    Thanks

    I have recently removed RM clock since I had sudden shutdowns when idle for a bit longer period...
    I followed guides for setting RM Clock with Turion TL-60 but these sudden shutdowns forced me to remove it...
