So I've got this Core i7 920 (C0 stepping)... I'm using a high-end aftermarket cooler (the Xigmatek Dark Knight), and it's getting way too hot. I have it overclocked to 3.6 GHz, but only at a voltage of 1.104V (in CPU-Z, I think it's set to like 1.150 in the BIOS), which I'm pretty sure is even lower than the stock voltage... yet when I put it under load it readily approaches 85C while transcoding video. I've tried seating and reseating the cooler multiple times, redoing the thermal paste, amongst other things... I don't understand how it gets so hot with a low voltage and a good cooler. It typically idles in the high 40s (though I've caught it as low as 37 before), and the first two cores are always 4-8C hotter than cores 3 and 4 for whatever reason. I've had this PC for a few years and I've never been able to get it right. Just for info I'm running it at 172x21 MHz with hyper threading enabled, and 16GB of DDR3 ram at ~1000 MHz (yes, it was still hot back when I only had 6GB).
What can I do to fix this? My CPU runs stably but I can't even run something intensive for more than 10 minutes before I have to start cutting back its core affinity to drop the temperature....
