Thats pretty good, What memory are you running? Have you changed voltages? i saw further up this thread that someone said to run QPI at 1.65, thats way too high IMHO. I didnt invest in ram cooling, never really needed it before.

Also the x58 seems to run hot as a mofo, im not running water on this box and shes cooks along, I needed to added extra case fans to get the flow over the heatsinks better! NB was at 50 odd degreesC when idleing... scary
I'm running QPI/DRAM @ 1.3725v, CPU @ 1.2625v, DRAM Bus @ 1.64v, CPU PLL @ 1.94v. DRAM timing is 8-8-8-22. I set CPU multiplier to 19x so I could get a DRAM speed of DDR3-1600 - I couldn't get DDR3-1800 long-term stable. I had no problem with BCLK = 204 stability-wise but had to back down to 200 so I could wake from sleep properly.

I'm using a Rosewill cooler that's going for $20 at Newegg currently - that thing is huge. I idle at 43-45c core temps, up to ~78c after a few minutes of 100% stress testing but remains there after an hour. Recovery back to idle temps takes only a few seconds. Lots of case stealth fans help .
