    idk what is wrong , maybe didnt apply the TIM properly ?

    need some advice on this please .

    Yah, you may want to try to re-apply the thermal paste and re-seat your kuhler h20 920.
    That temperature can kill the mobo in the long run.

    got an i7 2600k at 4ghz with 1.2v cooled by an antec kuhler h20 620 idling at 40degrees and full load at 60degrees with readings at non aircon room temperature.

    no it won't. this is not an amd

    true, intel temperature tolerance level is higher than amd.

    Yeah, but is still much higher than norm. My 2500k at 4.5ghz idles at 42deg and load at 64deg with a 620 kuhler. The 920 kuhler with thicker rad should do better. Look up videos on how and how much thermal paste to apply.

    what voltage are you on at 4.5ghz?

    2600k is about 4-6degrees higher than 2500k on hottest core.

    david's temp is same as my bro's 2500k @4.6k 1.298v but my bro is using d-14 with only 1-4degrees difference between highest & lowest core temp.

    TS's temp for 2500k no HT & having 6-8degrees of difference between lowest & highest core is showing a need to do re-seat.

    after dismantling the khuler's block, inspect the print of the tim & check your backplate if anything is restricting a flushed mount.

    its weird to have a 1.28v for 4ghz, looks high to me.

    1.290v. But my rads have 2 GTs doing push pull. Would say 2 fans drop temps by 2-3deg.

    The antec kuhlers comes with pre-applied TIM, so maybe if you changed cooler before, wipe clean the old TIM from your cpu until the silver surface of your cpu is clearly seen. Mount the kuhler flush tight to your cpu before you screw the thing in.

    1.2v for 4ghz is

    get this and it will show most of the hardware temps in your system, including voltages:

    CPUID - System & hardware benchmark, monitoring, reporting

    so i'll just dismantle the kuhler and re-apply the TIM and see how the temps are again .

    and should i lower down the voltage ? cause currently vcore is in auto .

    after re-applying the TIM , these are the temps at load . Only a few deg difference .


    and these are the idle temps


    is there something wrong with my antec kuhler 920 ?
    or something to do with the voltage ?

    Drop your voltage to 1.27v thru manual mode and see again. The higher your voltage, the more heat as waste is generated.

    Your idle is quite alright, how is your load temps taken? With games like bf3/crysis?

    i have a different approach to ts.

    - manual input vcore 1.28v
    - increase multi to 45
    - ibt 30 runs of high
    - work downwards & you should at least get a 4.2~4.4ghz ba.
    - change both fans to scythe gt.
    - for better performance of rad, change it to intake setup assuming you place your rad at i/o area & your top fans are exhaust.
