Well I read somewhere the other day that placing a 2p under the X bracket would help even out core temps...

System Spec: Q6600 - Lapped, Ultra 120 Extreme - Lapped

Prior to doing this @ 3.825 Ghz on my Q6600 my load temps were 68/68/62/62, the hotter two cores being the ones at the top of the CPU i.e. where the weight of the heatsink pulls the base most away from the CPU..

So after a couple of cuts (damm those fins are sharp) and a few swear words later had removed the heatsink and taken out the screw on the X bracket so that the bracket would lay flat on the 2p....

Then reassembled the heatsink with 2p (and much swearing!!) and rebuilt my rig...

after 30 mins Prime95 temps were as follows: 63/63/60/60

5c drop on the top 2 cores and a couple of c on bottom 2 can't be bad!!!

Have to say am pleased with the results still recon there is a little room for improvement... by pressing down on the heatsink can drop the temps to 60/60/59/59 so plan on trying it with two 2p's stuck together tomorrow evening... will report back then..
 
well i tried with * 2 2p and well increased my load temps by about 15-20c (didnt have prime95 open long enough to let it go above 80c!) so not a good thing... i'll be sticking with the 1 2p for now!
 
I think you may get better results using a washer. I picked some up from the builders shop for a few pence. Having a hole in the middle allows everything to sit straight but still puts a little extra pressure on the heatsink. I do this with the Ultra-120 I been using.

Combined with lapping both the CPU and HSF the overall results were worth the small effort.

Yes obv LAP it FLAT, then put a Coin or washer in, tha Yanks over on XS have been doing for age.

Just another fault of TR on some of sinks that are loose even after securing.

God my washer looks like its been unearthed from an 'Iron-Age' settlement!

Anyway just showing it so peeps get an idea of what to pickup from a hardware shop, works very well with the Ultra-120 (X)
 
am going to have a rumage through the shed on saturday pretty sure I have something similar and see what sort of difference it makes... really just want to try and even my cores a little :) 65/65/59/59 @ 5 hours into my Prime @ 3.825, would be nice if I could bring the two hotter ones down a bit or even them up to 61/62c across the board :)
