Core i7 860 idle temps and overclocking potential

Hey everyone at the TH forums. I recently just built my first rig, and with the invaluable advice from TH, I chose a nice set of components that didn't break the bank! (Many thanks =)

Anyhow, the build went off without a hitch. I'm running an Intel Core i7 860 (not OC'd) with a Cooler Master 212+ in my Cooler Master HAF 922. The idle temps bounce between 29-31 degrees C and my load temps after running Prime95 max out at 54 degrees C after 10 about 10 hours.

My question is, are these temps good enough if I want to try my hand at overclocking the CPU? Or should I think about reinstalling the cooler and maybe having better luck with my AS5 application? Let me know if my temps seem a little high with the aftermarket cooling, I'm a first time builder, and so far so good, but I'd like to see how far I can take this. Below are the rest of my hardware specs:

You temps seem fine to me. You have some headroom there, OC away!

Just remember to keep it under 70c during prime 95. If you see it pass that up then back down the voltage/clock. Up to that you're fine. You likely won't get your PC to those torture temps doing your regular uses anyways.

Let us know how it goes. :) 

Remember, we have an overclocking section in Tom's forums as well. You'll find more overclocking gurus in there.

I have my i7-860 running at stock with a Noctura NH-D14 cooler and no matter what I do, I can't make it run hotter than 55c.

For the most part it stays below 42c when busy, and idles around 5 to 7 degrees above my room temperature.

Your temps look fine. Remember that the temps will drop a couple degrees once your AS5 breaks in.

I recently built an i7 860 system for an engineering customer. I also used the Hyper 212+ and did a slight overclock. The customer wanted the system to use little power when idle, but put the hammer down when needed. I ended up leaving turbo enabled and doing an overclock that pushed the speed range to ~3.2GHz - 3.85GHz instead of the stock 2.8GHz - 3.46GHz range. I left the voltage settings on auto and left Speed Step enabled so the system was able to idle at ~1.5GHz at .8v. The system never got over low to mid 60's under full load at those settings.

I know that's a little different method of overclocking than we're used to, but my customer is very happy with the results. The system sips power when it's not needed, but has the higher clocks available when it needs it. It was also completely stable under multiple days of torture testing.

This overclocking method isn't for everybody, but I was quite happy with it.

I would kill for those temps, with my i7 930 1366 ga-x58-ud3r system I idle 47-52 and when overclocked to 4ghz I idle at 55C I picked up a Megahalems cooler, I have a well vented case, I really need help, There is something wrong here, I have every part blowing cool, my northbridge is what idles high, around 52-54, I have re-seated the cpu many many times with various thermal pastes. Any ideas? I dont want to start another thread yet, my other issue wasn't resolved.
