That's a nice OC and great temps for the 960.

+1 ... great oc, Layback Bear.

Running a cool 4.2 on a i7-960 at 68 deg c prime 95 100%

Nice OC, good temps and minimum voltage, well done

...1.584v is very high, you should be able to get around peaceful's 1.368v, or lower

I'm sitting at 1.38 right now. I'm going to finish up a few more tests and see if I can shave a little more off. I backed off the 4.9GHz I had before but am currently at 4.62GHz with the new lower voltage.

On this i7-960; don't use XMP it drives the cpu vcore to high and their for hot. Max is 1.375 as per Intel. XMP will drive it over 1.40 volts and very hot quickly. I presume if you have enough cooling you can do that. The memory controller is on chip so if I get this chip to hot the memory takes a dump and the computer shuts down. Some day when I get in the mood I will tinker with it some more. At the present time the motherboard RMA from Asus took care of the ram problem with a very old bios and a new board. That make me happy. At the present I'm running cool, quiet, and quick and I'm happy.
NOT in the mood to change things. Maybe later. I was thinking of Corsair H100 but they made it in a fashion that it doesn't fit in the top of my Corsair 600T with push pull fans well from what I can tell. To do more means I need better cooling. I have got a ton of money in this thing already. All the stories of poor case cooling in the Corsair 600T does not show up with me. Great cooling hear with a little common seance. Well I have been long wind-did.

That's much better

Core temps?

You might consider the H80, smaller footprint radiator than the H100, but thicker.
Same CPU unit and electronics.

...Core temps?...

According to RealTemp they are:

Idle:

Core 0: 43
Core 1: 44
Core 2: 46
Core 3: 45

Prime 95 after one hour:

Core 0: 80
Core 1: 88
Core 2: 87
Core 3: 85

Not nearly as low as I'm comfortable with under full load. I am using the Corsair H80 and have the fan set at the middle setting - full speed is just too loud.

My room is hot right now - 80F. Maybe I'll try it again with the windows open.

Thanks Dave I will do just that.

Even with your ambient temp the idle temps seem a bit high. Would expect low to mid 30's.

When I tested my H80 with stock fans on medium setting my idle was sub 30 (due to ambient) and Prime95 was 50°C for the highest core temp. Of coarse my CPU isn't OC'ed as much as yours but, idle temps should be similar.
When I have ambient of 80°F the idle temps are 30°C.

Might want to check the thermal paste and the mounting bracket.

If the noise to too much, look at the Noc fans in my sig specs, they are for CPU coolers and are very quiet on the high setting

I was looking at the H100 but, no way it would fit my case so went for the H80 and I'm very happy with it.

I was right around 40C at stock speed. I just built the rig about three weeks ago and was careful with the thermal paste, etc. I'm sitting at 42C right now with the overclock.

I've heard good things about those. I will definitely consider a pair of the.

By the way, I followed Corsair's advice about using two fans in a Push-Pull with the intake end at the back of the case. I wasn't to sure about having the hot air from the CPU blowing into the case, but figured the 200mm fan exhausting out the top would take care of it. Is that how you set up your H80?
