    Hello all :)

    my system is:

    cpu: intel i7 920 @ 2.67
    gpu:gainward gf gtx460 1gb
    ram: ocx gold 3gb ddr3 3ple channel 1600
    mobo: asus rampage II extreme
    psu: tagan PipeRock @700w
    case: thermaltake armor
    running windows 7 ultimate 64

    had before some overheating issues with my cpu so I change the stock cooler (that sucked actually) with a coolermaster N520 @ 1800 rpm

    lately due to the hotter new gpu and the overall summer heat here (38C outside atm)

    case temp rised somewhat so cpu temp on load rises to a peak of 74 (on Starcraft 2, while I was benchmarking my gpu with furmark etc)

    since it was a lot I looked it out: cooler was working ok had good contanct with the cpu etc

    so at the end found out counting it with HW monitor PRO 64 that the cpu was getting 150 watts during low load times (19-25%) so I guess this is what causes it to overheat.

    Thing is I am not pretty sure what to do about it ...

    anyone has experience on this?

    thanks in advance ^^

    air condition the room the computer is in and keep the temps around 20' c. If need be, install a AC window unit.

    Yes one day when it was +30 C and I was running +4 GHz 100 % CPU.

    1. Check Vcore in bios / Z-CPU. If there is no OC then 1.18 V is absolut max needed.
    2. Too little air flow in case?
    3. Better seating of heat sink. Yes, I did read that you think it is OK, but I doubt that is the case if 1 and 2 is OK.
    4. Better heat sink
    5. AC
    6. Stop playing ;)

    Good luck.

    74 its a bit high, i7 have high range temps but with stock speed i see your cpu cooling didn't work well maybe thermal paste set wrong, but you can decrease from bios that by decrease cpu voltage cuz intel always make cpu use higher voltage than it need for save stability also disable fan controller and make cpu fan run at max speed all the time
