ive had my 920 for a while now on a fx-8150. nice guide by the way. when i was screwing the fan onto the rad i didnt think it was getting very tight (like mentioned before) so i gave it a bit more of a twist and have subsequently dethredded the hole so the screw can now just pull straight out but its working fine with no vibrations

However im not a fan of how much this cooler blocks the vrm's and hangs over the cpu socket. i think its reducing the airflow to the vrm's a lot.

also i cant seem to get my 8150 over 4.2 without massive heat gains

Stock antec coolers.
I will test again with prime95 and cpu-z

Your 920 is under performing. You have a 77w chip with no OC. Your fans aren't hitting antec spec: 700 - 2400 RPM (PWM controlled) 110.0 CFM.
Can the fans get above 2200 RPM on Extreme setting? Is your pump speed near the top of it's scale? Mine is always around 2880 RPM.
Is the unit plugged into a Throttled Down or damaged mother board CPU fan header? Mine is dammaged now, I use an adaptor to power the 920 from 4 pin molex, and it has a 3 pin fan tach connector for the motherboard. Try powering it from a 12v molex by using an adaptor. You may have to shut off the motherboards CPU fan alert, or simply fool it by pugging a different fan in there.

look:
Where i can undervolt?

UNDERVOLT?
I would leave it on AUTO if you aren't OC'ing.
However, if you got OFFSET option that might be better.

Regardless of what I said above however, i would go into your windows power options and modify the power settings.
ie. go to balanced, and you should see the CPU downloading from 3.6ghz to 1.6ghz

Not that high - I can get 40c liquid temps and 90c CPU temps.
All depends on the voltage really.

Glad the guide could come of help - and yes the de-threading of the backplate I know exactly what you mean - that's the problem with having a silly plastic plate that antec provided us with.
If it was metal, we wouldn't have a single problem.

That's good advice right there.
Yeah on extreme the fans should RAMP to 2.4k

In extreme mode fans get 2580 rpm.
Pump speed is around 2950 rpm.

Today ambient temperature is better. I will do some tests.
Idle liquid temperature : 33ºC
Yesterday liquid temperature was 37ºC.

just a quick question. can anyone point me in the direction of a decent sabertooth 990fx overclocking guide as im sure i should be able to get more out of my chip than 4.2 with this kuhler.

start ramp 30ºC
end ramp 40ºC

i5 3570k turbo boost off, 3.4 ghz


temps estabilished at 49 ºC biggrin.gif

Told you your temps were fine and it was down to ambient thumb.gif

Out of interest though, why is your turbo off?

Ok, we can rule out electrical problems.
