Bob,My EVGA gtx 480cards are set up in SLI with stock SC settings.My CPU has the multiplyer set to 30. That's all I've set. The highest temp I've noticed was 60.Most of the time my cpu temp is about 42c. That's using an Ultra ChillTec cooler.http://www.ultraproducts.com/applications/searchtools/item-details.asp?EdpNo=4387079&csid=_21Not problems running FSX with an unlimited setting and BP=0.

Thanks...42 deg is probably cool enough not to worry too much about the IMC cooking...and your O/C isn't super aggressive so that makes sense to me.When those Peltier Junction coolers fail, it's sudden and with no warning. If you're not already, I'd really recommend you run something like RealTemp as a standard background process set to scram the PC if core temp ever exceeds 80 deg C. That way if the Peltier junction fails, the PC will auto-shutdown without smoking the CPU. When a PJ fails, the heat transport mechanism quits and the ceramic face of the heatsink suddenly offers little thermal conductivity to the CPU and the case temp shoots up rapidly. I had a bad experience with a PJ heatsink some years back on a Pentium IV machine. When they work, they work great. When they don't, they don't work at all.CheersBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

Bob,I monitor the temperature often with the digital read out.If this cooler ever fails me, there are some excellent air coolers out there.Which one is your favorite?This one intrigues me.Noctua NH-D14 Heatsink

I have the DH-14 cooling a 980x clocked to 4.43ghx - max temp under OCCT full load over 1 hour - 72C. Running FSX, hardly gets to the 60's.BUT - it's a BIG sucker - be sure you have room and be wary of the memory stick heat sinks that stick up too high. Amazingly quiet though.Vic
