Hey, Ive just installed an Asus Silent Knight II on my Asus P5E-Deluxe + Q6600 combo in the hopes of dropping my temps to do some decent OC'ing.

However, Im using Zalman Super thermal grease and My idle temp is like 45-50c...

Ive reseated it numerous times (reapplying thermal paste each time, and cleaning the surfaces with thermal remover stuff)

When I run prime 95 its hitting 65-70 at stock speeds

As ive never really done much with thermal compound Im pretty sure Im not applying it right?
Ive tried applying it to the cpu, then to the base of the fan instead, then a little bit thicker then a little bit thinner etc etc yet i still have **** temps.

Any ideas?
 
Best way to apply that thermal paste, if its the one that comes in the nail polish type bottle and brush.

Is to do a thin layer on the cpu, and a thin layer on the heatsink too.

Also make sure the cooler is firmly attached, as having little pressure will hinder cooling.
 
Ok, Well I did that, the layer on the cpu was nice and even, the one on the cpu gets lots of brush strokes which is annoying and difficult to get rid of.

However, idles at 35c, when the case is on its side, 50c prime95 temps, when i picked the case up the temps shot up to 100c, and back down again when I lay it down.

So obviously its the pressure from the heatsink, but I cant see any other way of fixing it on :S
 
Just had alook at a few reveiws of that cooler, backplate and retention clip way of attaching it, ok not the best way, but that should be plenty of pressure.

Mmm im not to sure why its doing that if its been installed correctly, best to wait to see what some others will say.
 
i think the retention clip might be bent or something, obviously for the clips to fasten over the hooks on the bracket, the lever is on a hinge so u can bend it enough to clip it onto the hooks, the problem is its supposed to straighten up when u depress the lever, mine doesnt, so its not putting quite enough pressure on.

When the case is laying flat on its side my temps at 34-35c idle, when i stand it up, they jump to 49-50c idle, and by putting a little extra pressure on the heatsink with my hand they drop another few degrees.
 
So deffinatly a pressure problem, sucks that the retention is'nt working as it should, maybe e-mail asus and ask them if they can send you out a new retention bracket and stuff.

Explain to them your problem, hopefully they will just send you out a new kit for it, if not then maybe some forum members might be able to come up with some ideas to help mod it, so it works.
 
you would have been better with the megalohem or whatever its called or a TRUE, i read reviews on those asus heatsinks and they are not the best performers ;)

additionally does your case have good airflow? that could help temps slightly.

on my old motherboard and q6600 i got upto 3.8ghz with a TRUE 120, load temps from prime never went over 61c, idled around 30c.
 
Yeah It was a toss up between the thermalright and the asus, the reviews i read were good on both, and the asus is supposed to be a very quiet runner, and a few friends have used them and got very good results.

Wish i had gone with the true now tho lol. Im going to email asus and ask for a new bracket at least, its out of its 14day return period with OCUK now as it was bought for me as a present, and was bought a long time ago =/
 
i like the TRUE because of its flexibility, i mean you can mount any two fans you want on either side as high powered or low noised as you want.

with the reviews you need to check the sites that review it, if the site that reviewed it performed overclocking tests with it they normally show benchmarks on cooling compared to the other heatsinks, if it was a standard review it proabably would get good marks.

check out my recent new pc build (link under sig), you can see my true in the tower with 2 fans mounted - they are beasts for air cooling ;)

I also dont use any thermal paste or compound that comes with the heatsinks, get some arctic silver or mx-2/mx-3 paste.
