Hey, I'm currently running an i7 920 with a Noctua NH-U12P (Using provided compound). The instructions said to just apply a dot in the middle of the CPU and then attach the heatsink, however I was under the impression from a guide I read that it needed to be spreaded, so I did that.

My idle temps are around 35C and a stress test on prime95 gets it upto 55C+ (58-60C is the max).

I was wondering how good/bad that is? This being my first build, I may have done something wrong or whatever. I was planning to overclock, do I have enough headroom to do so?

My cable management is good, I'm using a Antec 902 and the are no wires between the top front fan and the heatsink intake fan.

If my temps are actually too hot, I was planning to use some AS5 and just apply a pea sized dot to the middle of my CPU then attach the heatseak, would this work?

Looking forward to the comments, and thanks

Kasc.
 
I would say that was excellent coming off an i7 rig.
Have you overclocked at all?
I am running a Q6700 @3.6GHZ with a Zalman 9700NT I get around 40c idle and 60 max Prime 95
 
Those temps seem fine, what are you using to measure the temps and to stress the system ?
You got loads headroom to oc, as long as load temps are under 80C you are fine :)
 
Sounds good. Whack the BCLK to 200, voltage to 1.3v, and turn turbo mode off. Should give you 4GHz. If it doesn't boot, either try upping the voltage (no higher than 1.375), or lowering the BCLK. If it does boot, run Intel Burn Test for 20 minutes or so, this should give you a rough idea of stability. If it doesn't crash, keep lowering the voltage until it does. When it does, put it back up one or two notches, and run Prime95 for a nice long time (overnight or something).

That's pretty much how I did mine.
 
Will do, what's the upper limit for the temp?

Also thanks for the help guys, much appreciated!

EDIT: Also, I remember hearing I also need to overclock the QPI, is this true?

Quite a brutal approach there Danneh, but I agree it would work. Wondering why you suggest turbo mode off when most people seem to have it turned on?

Limit is 67.9 degrees in bios. Some temperature programs can report this one as well. Limit in software is a discussion unto itself, most people seem happy if below 80 and a bit worried if over 90.

bclk 191x20 (will go to 21 under load)
turbo boost on.
QPI clock x36
cpu clock cycle 900.
uncore freq (double ram speed) usually 3200 for 1600mhz ram.
performance enhance. turbo.
xmp profile off.

ram timings depend on your ram.

voltages:

LLC off

cpu vcore 1.287v
qpi/vtt 1.215v
ICH 1.14
Ram 1.5v or 1.64 with xmp profile.

that should get you started....


Dont let all this talk of bios temp and core temp confuse you, use realtemp and keep the hottest core under 85c and you will be fine. The bios temp is taken from the socket sensor and the core temp is taken from the core sensor so they will be different. 67.9c is max for bios temp and 100c is max for core temp. keep core temp below the 85c core and the other temp will be under the threshold anyway.

I only turned it off because I like a nice round 4GHz, 200x20 is a nice number :p

Of course, if it won't do that, by all means try 191x21, just saying what worked for me. It's been rock solid since.
 
Currently have it clocked at 3.5Ghz (166x21), load temps have hardly changed, I set the CPU Vcore at 1.2 via the bios but CPUz is showing 1.15. Currently running a prime95 stress test, no problems as of yet and the max load temp of the cores is 62C
 
Ok guys here's where I'm at:

166x21 Passed the test getting to a max of 63C with my case fans on lowest.
Then I tried 191x21 @ 1.2V and but i was getting system chrashes until I increased the vcore. Now I'm at 191x21 with the vcore at 1.3v with a max load temp of 70C. If this test passes do I need to start reducing the vcore until i start getting chrashes again then go back up a notch on the voltage?

Thanks for the support being this the first time I've done it :P

yes, reduce the vcore until it crashes and then increase by 2 notches.

200x20 with turbo boost off, will take a bigger voltage. I'd try the 200x20 with the 1.3v and see. I can get stable 200x20 with 1.275v LLC on but need to mess about with memory too much for my taste. I can get 8,8,8,24,2t at 1528Mhz with 191x21 at 1.5v, but the same takes 1.66v at 200. Remember higher voltage, higher temps.
