Hi I'm pretty new to these forums, but I've been having look at a lot of really helpful info you guys have posted around here! Thanks very much!

Anyways, I recently built a PC running an i5 2500k, Asus P8P67 Pro, 4GB XMS 1600 CL9 MHZ, HD6950 2GB with a Noctua NH-U12P SE2 CPU Cooler.

I found even on fault settings my idle temperatures might be a bit high. It ranges from 30-32 degrees at idle.

When OC-ing to 4.5 Ghz with a CPU Voltage of 1.24 in Bios it gives a Max of 62 to 69 Degrees when running Prime95. Does the range of temperature seem a bit high?

I've also noticed that with CPU-Z the Core Voltage sometimes ups to 1.304, which is quite a bit higher than the 1.24. How can decrease the range of movement of the Vcore? Or is it not necessary for this small OC?

My aim is to keep it as a 24/7 OC. I am not really looking to go over 4.7 GHz and am quite happy with the 4.5 GHZ. I am still running Prime95 as we speak and I willl leave it on over night.

What could be my suspicion is I might not have correctly put on the Thermal Paste for the Noctua cooler on correctly, since it was my first time doing it manually (before I had an Arctic Freezer Pro 7 which has the TIM on it already). I just put on a dot of about 5mm, then pressed the heatsink down.

If anyone could give me any advice, would be really grateful, thanks!

Eist will lower vcore @ idle.

LLC will increase vcore proportionally to cpu loading.

If LLC is on auto tweak it(manually set it) and try on each setting to see if movement is as before.
ie: try LLC [regular] or [med] or [high] or...to [extreme].

See if setting to any of those values helps your situation to stable vcore.
Your load temps at 1.24v are good.
I intall TIM same as you, works for me

Thanks for the advice! Actually I think because I accidently didn't save the manual voltage setting, and so before it was primetesting with a vcore of about 1.303 which is pretty high for a 4.5 Ghz OC.. So trying to do it again with manual and 1.265 vcore. I'm still pretty confused about a lot of the bios settings but I switched Internal PLL Overvoltage off.

I've also been having the Sleep bug with Windows 7, so I hope the Internal PLL Overvoltage will help solve that!

EDIT: Temperatures looking even better; maximum range is between 54 to 59, and Core Voltage on CPU-Z is giving 1.24~~

That is a nice motherboard.

If you corrupt your bios, you have crashfreebios.
just keep your MB cd handy for that
Your user manual has some info on that probably.

Edit> I located a couple MB reviews, some bios info in them>
