I can't downvolt my gpu because I can't damp or backup my v-bios. witn cpu-z 0 results and nibitor 0kb of backup.rom. please help my. my gpu is 58-62°c surfing the net and playing is 72-75°c (10°c lower after cooper mod and cleanig).
    with my cpu after thermalpast and cooper mod (mecanical jobe) I obtain 74°c under stress and now my cpu after undervolting obtain 10x 0.9625V a temp of 62°c full load. and my ambient temp is 35°c (living in Sicily, Italy in sumer time outside is 40°c)

    I dont think these temps are anything to worry about considering the insane ambient temperature

    74C is about 20 degrees from what you could call overheating.

    You're fine.

    ok but I want a cool lapyn. my cpu is 45-50°c idle and my gpu is 58-60°c idle and want to make it go lower (for temp not my grafic power gest volts for run cooler).
    I know that I am runig at 74°c on full load but is not prety if I can get 10-15°c lower and safe the batery for more time.

    maybe powermizer aint working so your GPU doesn't downclock/downvolt in 2D-Idle mode ... check that with GPU-Z ... a friend of mine had that problem with 8600GT and certain drivers

    You're not going to get it much cooler than it is right now. I mean it's idling at 5-10 C above ambient, that's not bad.

    as Hockeymass mentioned & as I mentioned in my first post your ambient temperature is quite huge so ur GPU idle temp aint that bad to give u an example on my 0.9 v idle voltage & ambient room temp of 23~25 C my GPU idles at 40~45 C & all the way up to 50 in light load ... so once again I think yours aint that badly especially for 1.15 volts & ambient temp of 40 C
