    Definitely a heatsink contact issue. He has to find something else other than Furmark that highlights that this is the case for RMA.

    Yes but the seller has said there's nothing wrong with card, so you can either try contacting MSI or you can try fix it yourself.

    It's designed this way. According to reviews, this card draws nearly 400W at max (FurMark) load. Having that in mind, its dual slot dual fan cooler performs pretty good.

    That or bad cooler, bad batch.

    In another forum(ocuk) there is a big thread talking about the msi 7950 high temperatures.There is a contact there, maybe you can use it to rma directly with msi.

    the power edition is a different card with known issues, imo after much research the 7970 lightning is best card of 2012, it's cooling is incredible, ok maybe this particular benchy doesn't like AMD cards but all the same, even the mid-eithtees are too high. (like what catzilla used to push mine too before paste change and re-seat. - now it's -20C cooler under load).

    400W would be the total system load, I'm guessing. If this card alone was 400W, hooboy...It wouldn't consume double its rated TDP of 210W.

    Reference 7970 is officially rated at 250W. Lightning has a very beefy power design, which is the cause of such enormous power draw during FurMark

    [​IMG]

    According to TPU review, the card alone draws 380W during FurMark and a lot less during regular gaming http://www.techpowerup.com/reviews/MSI/HD_7970_Lightning/26.html

    A similar thing can be seen with GTX 670 cards which use GTX 680 PCB. Gaming power consumption is not much higher than reference, but maximum power draw is much higher, similar to GTX 680.

    It's a non-reference card... Power consumption can differ. A lot. And reference 7970 draws up to 270W.

    @XBEAST: Dammmmnnnnnnnnn, how is that possible? Where is all this power going?

    On the other hand, in that same review:
    http://www.techpowerup.com/reviews/MSI/HD_7970_Lightning/32.html
    The GPU maxes out at 76C. I'm guessing that is on Auto fan. Even if it was on 100% fan, that would still be much less than the 97C the OP is getting.

    No more than 70C @ 60% fans. Temps are quite the same while running Heaven, 3dmark and BF3 multiplayer.

    @ Xbeast: I'll try to buy a wattmeter to see the power consumption while running Furmark vs. Heaven. If there is a big diference than is clear why the temps are so high while running Furmark.

    The lightnings are unique, never run this benchy again ever, and enjoy your games! Your card sounds fine. :)

    @SLI-756: In the techpowerup review linked above, the 7970 Lightning gets to 76C under Furmark. There's definitely something wrong with this Lightning here.

    Thanks for the reply.
    I tried to OC the GPU. It goes up 1230 Mhz with 1.25V. Tried even higher but no result even with 1.35V. Any tips? Maybe switching to LN2 bios?

    What are you stress-testing with?

    I'd avoid OCing until the temperature issue has been resolved.

    I'm testing with Unigine and 3dmark. In the techpowerup review the reviewer doesn't say anything about testing with Furmark. I think the temps test is made while running HwBot Unigine. That's the same test used by matose@Lab501.
