    Yeap, if i post a picture of how many thermal pads i have stored up , people will have a seizure.
    End of the day anything above 7w/mk doesnt really doesn't make a difference, since the heat sink cannot dissipate the heat fast enough to keep up as it is.

    Mine is customized to the ASIC of my cards in my machine, its unlikely to be stable in another machine.

    Every degree you can reduce..., 2-3 degrees lower temp in bench can be the difference between success or failure:D

    I have a feeling is simply a poor quality heat sink not making good contact. It happens. I had this problem on my CPU heatsink recently. 4.2 ghz would give me temps that approach 100 degrees. Although it's a roll of the dice I purchased a new heatsink and now 4.5 nets me under 80 degrees under load.
    If I were you I'd just buy a new heatsink. It's probably cheaper than experimenting with expensive Fijipoly pads which I think is unlikely the cause.

    Seems more likely to me, Since the heat up is really too much of lately and never had this with running maxed out for long sessions !!

    Heatsink and Fujipoly same price, I ordered it, Will test everything out now...thanks for the idea +rep.

    I like this machine and a personal reason also makes me not to part with this soon, Hope I get things fixed.

    The truth is the voltage on the 980M is so obscenely high....without Prema's help, the card would have surely fried itself for now. I'm running undervolted same as Ethrem, though his may be a slightly stronger undervolt. I'm running stock boost cocks, but at 1.000V cap instead of that ridiculous 1.0675V it originally ran. Since then my black screens and temperatures have been phenomenal in the M18x R2, topping out around 73C in my warm room or even under 70 C in a cool room. 980M should not be volted so high, its just too much in such a confined space. Boost clocks on the standard prema vBIOS we are talking like 140W power consumption, no wonder nobody is able to keep it cool

    I'm not that much further under you. Prema stopped at 975mV. I'm pretty sure these cards could go lower too. I still can't game though... Summer here in Denver is one of the hottest on record and our A/C just can't keep up... it regularly goes over 80F in my room now. My 4940MX is idling @ 50-55C...

    I feel you man, the ambient temp in my room is 82+ because the vents do not work in my room. I'm ready for winter!
