So I just got up & running after a good scrubbin'...

Of my heatsink, that is :) I've been running Orthos back @ stock for about 20 minutes now, and so far my temps haven't broken 39ºC :D I'm happy. Before it would routinely hit the mid-high 40s, sometimes 50 under stress, idle temps haven't changed. After stressing it for probably a couple hours so the compound can break in a little I'll go back up to 2.4 & see how she runs. Wish me luck ;)

Oh... by the way... pictures to come :)
 
better off removing the IHs on that X2 or at least lapping it if you want to drop temps. of course IHS off with heatsink will need modded to make contact with die. but then well worth it, when I delidded my X2 4800 way back, dropped load temps by 10-15C.

as soon as my lapping kit arrives im going to lap this QX6700 as its a bit concave.
 
Links for said method? It didn't make a huge difference in temps, but I do feel better now that I know the heatsink mating surface is flat (it was ever-so-slightly concave). I'm a bit nervous about doing it on the actual cpu, not sure if I'm that hardcore quite yet, as I don't really have the extra money to spend on another CPU if I royally screw things up.
 
i handlapped my 2 zalmans befor placeing it my vid card one had 4 defects in it so far my comp hasnt broken 37 yet under load even..

when i handlapped i got the flatest piece of wood put sandpaper on it

started with 360 grit
steped up to 600 grit
steped up to 1200 emery cloth
finished with emery cloth at 4000 grit

then got some mothers polish and waxed and buffed with microfiber cloth it befor insalling

edit DO NOT USE any sandpaper other then >>>>>>>>>>>emery / aluminium oxide / silicon carbide<<<<<<<<< anything else used on metal WILL leave contaminints in the metal and it WILL reduce the effectiveness in your heatsink and it WILL cause corrosion
 
I work at a plating shop so I just had one of the guys in polishing Diamond Polish my tuniq tower to about an SPI A-2 finish on the base, he couldnt quite get an A-1 finish but its good enough. I cant wait to test it out.

 
What did you do?

BTW - nice temps, lol and good luck:D


Thanks :) This was my first time doing this, I wet sanded with 3M Wetordry 220 grit, then 1000 grit, rinsing the paper & heatsink base every minute or so to keep the copper from clogging the paper. For a flat surface I used an inexpensive, ~10"x10" square mirror. Sorry I haven't gotten to the pictures yet :p
 
So, we finally have picage... it's not the smoothest looking job, but it's flatter than it used to be :)

So first, we have the processor in all her glory :)p)...

And the tools to do the job:

It's not easy to tell here, but the next pics are after about 10 minutes and a half hour (@ 220), and the final product (@ 1000):

This is almost the amount of thermal paste I used (actually wiped a little extra off my finger after I got somewhat even coat on the cpu), along with the cpu covered in the stuff:

Any thoughts?
 
Even though I've done it in the past, even with S754/939 processors, I no longer cover the entire CPU in thermal paste. Just a tiny rice sized drop in the center of the processor.

I did it one day with an equal spread on the proc, then with a rice dot. No change in temps.
 
For AMD 64 CPU you only need to put a dot of grain in the center of CPU, and it will spread out eventually when you tighten the heatsink.
