My Results of Lapping

realscot · 28 Feb 2007 at 20:18

Rig1 in sig E6400@3200
Used some 600 & 800 Wet and dry to lap my cpu and my Scythe Ninja. Took the cpu down to the copper, it wasn't all that bad but still took nearly 10 mins of rubbing to get it all down to copper.
Anyway, the before and after. Used intel TAT to monitor temps and also apply full load to both cores.

Before Idle 40/41 Full load 52/55
After Idle 30/32 Full load 42/45
(CORE1/CORE2)

I'm happy with that. Will give the tiny bit of AS5 I applied time to settle before I knock my overclock up a bit.

*EDIT* Just loaded Everest to check temps in there. It's saying the CPU's IHS is 23c on idle. Nice.

Not bad going 10c drop :eek:

, might have to try this with my ES6300

Idles around 48c with std HSF

nice result any pics ?

Yeah fully - Pics Please!

sorry no pics. Didn't have a camera handy. I havn't made it mirror finish though, i'm not that anal.
It's not as scary as I first thought really. I just got the 3 different grades of wet and dry and selotaped them to the kitchen table (much to the missus's disgust)

then just did the standard 3 rubs, turn 90degrees etc, till all the silver paint or whatever it is, is gone and i'm left with pure copper.
The sides started wearing first, as i suppose almost all cpu's would have done.
When I lapped the ninja it really didn't need much of anything, about a minute on each grade.
I really have just a tiny spec of AS5 on now. Just enough to fill any grooves left by sanding. I don't mind that my warrenty is ******, i'm running at 3.5 now with 40c idle and 52 full load. Gonna leave it priming all afternoon as I have to go back to work!

Must do this; my E6400 is up to 60deg load @ 3.6ghz on my watercooling setup but my rad is cool to the touch.

[edit] try 70deg w/1.6v and fans at 7v, still cold to the touch :eek:

The concave IHS strikes again

Ok i did it up to 1500 grit, Halfords has all the grades you need for wet & dry.

Temps have dropped to a max of 62deg load. I think i need a new CPU block as i can't get my Cascade centered over the processor (and after all it was specifically designed for small exposed cores).

For a Core2 its not the best block

Going to give this a go my self, I assume the smaller grade the better? Going to raid my lab down stairs as we have lots of equipment for polishing nano-micro electrodes

will do the job.

edit:

some pics of lapping that might be of intrest

link to guide where I fund em is here

They also tryed to take the IHS off but the cpu died
