    I keep having bursts of low fps every 7 seconds or so in almost ALL games. I've repasted the CPU like 3 times, so I think I've eliminated that as a possible cause. What on earth could cause it to go up to 80 degrees c then back down to upper 50s with nothing open on the desktop? Does anyone have any ideas or experience with this that may have some suggestions?

    Another VERY odd thing is that when I open up the control panel and look at maybe my windows experience index, for some bizarre reason, the cpu goes down to like 47 degrees and the thing chills out completely. I mean what in the world could the issue be?? Sorry for double post.

    What have you pasted your CPU with?

    I did this more than 3 times with same result, not beeing good until I used Diamond compound.

    It cuts on 80? I got WAY higher. Seen in HWINFO64.

    I pasted it with Noctua NT-H1, which I've heard rave reviews about.

    If you have this kind of troubles then I would reinstall OS.

    Also you can test your CPU using Intel burn test or Prime 95 to check it's temperature. What if your GPUs throttles, not CPU?

    My 6990m(s) are both like hanging around 50c in Smite with maxed settings while my cpu is going bananas. I ran wprime 1024 across all 8 threads and it got up to 94 degrees :/ pretty darn high.

    I think you may be right about the os, but I'd just hate to reinstall it to find that I have the same issue.

    I feel like maybe the heatsink isn't doing its job anymore? Would that make any sense given my problem?
    Also I'd love to know if reinstalling windows could do the trick?

    Doubtful windows reinstall would help. I've had a heatsink go bad on me before in my M17x R2. CPU 940XM would overheat regardless of how much I adjusted the tension on all the screwes. I tried adjusting the heat sink while the system was running wPrime 1024. On the end the issue was solved by getting a new heatsink.

    I tried repasting a lot. New heatsink and I was good to go.

    Have you tried setting the fans to run faster manually with HWInfo?

    Just monitor your GPU activity at the same time, because fully loaded your prime temps are normal.

    If you could post a pic showing graphs with CPU frequency/GPU frequency, loads and temperatures, that would help make sure the problem in pinpointed.
