My i7 920 idles at 50ºc and under about 1 minute of prime95, hits 95-100ºc. it's OC to 3.8 and i'm using the dark knight hsf. core voltage is 1.336 if that helps.

any ideas?

Downclock and reduce voltage or reseat the heatsink.I'm not sure if the xigmatek dark knight can cool an i7 920 at 4ghz but you have to keep the temperature below 80c and as some prefer maybe below 75-70c.

went back to factory settings (no OC), idles at 40-45.

wight prime 95 going for ten minutes i'm receiving max of 79, 78, 75, 73 in real temp

asus AI suite read about 71º max on the cpu. 32º system.


after another 5 minutes in, asus ai read 46º, and real temp read 51, 58, 58, 46. still showing 100% of all core usage.

then back to idle at ~40º.

does it sound like i need to reseat, or is this about right? (again, all factory default settings where it auto turbos to 2.8 and idles at 1.6ghz)

You need to reseat your heatsink.Don't trust asus ai because it shows 20c less than what the real core temperature is.79c is unacceptable.You need to reseat.

okay. think it's not screwed down tight enough, or use arctic silver the wrong way? (all of the above?)

anyone know the best way to remove as5? or techinique for getting it off the processor?

q-tips and rubbing alcohol.

mine idles at about 25C so I expect you have a HSF seating problem as said previously.

Ive used that cooler on an i7 before and its a no go for that high an overclock.

I got fed up and bought a H50.

That cooler is weak for i7. I7 runs hot especially when overclocked, you need real good cooling.

Sounds like you might have cooler issues. My 920 is cooled by a NOCTUA NH-D14. O.C. to 4ghz (1.25v). Idle 43-46 and after 20 passes of Intel Burn max temp 69-71. After 24 hrs Prime 95 max temps 68-71. Please note the the room ambient temperature has a lot to do with your temps. These are not exceptional values and I hope they give you a comparison.

I'm currently using The Xigmatek DK on my i7 920 clocked @ 4.0 GHz and haven't had a problem, temps don't get above 75c.

OP: Maybe you should re-seat your heatsink as others have posted. I had to do this because I wasn't happy with my temps the first go-around. Just apply a small amount of rubbing alchol onto a Q-tip, then slighty rub that over the old thermal paste on your HSF and CPU. Then get everything clean and apply more thermal compound and attach your cooler and you should see better temps. :D 

Another thing I want to mention: Ambient temperatures, if the location to were your PC is at is quite warm, it will have a substantial effect on your overall temperatures.
