Thx guys... i will try using cheap heatsink to gain experience first...

can we lap proc surface also...

both heat sink n proc shinning... sure good contact

yeah u can...been done many times before.

yea! lapping your proc and heatsnk will surely give an excellent thermal transfer.
but lapping the proc is not the same as lapping the heatsink, u nid to search at google for lapping processor guide.

u need to be extremly carefull if not kau kau.... but if ur proc is no more warenty like mine..then go ahead...as i will as soon i am done with my stupid exams

I dont understand y it isnt the same. Mind explaining more?

well first of all if too much water... can die..if u damage the pins die. if u damage the contact tpoints die.... theres lots more things u need to be carefull with....

actually lapping processor and lapping heatsink is the same.... the only diff is that the precautionary measures for the proc are more.

other than that..the steps etc are the same one

Does it matter to go another 3 more degrees and risking so much of money....???

i would rather go for better cooler than spoil my proc... regardless how cheap is it ... since it would definitely cost more than a high end cooler ....

To the people that care it matters, to the people that don't care it doesn't matters.

ok, here's a great guide for lapping CPU IHS!

Well, a 775 package doesnt need to worry so much Just make sure it's dried fully though...

Hey, sry to tumpang topic.. When ur lapping your hsf, do you use the sandpaper to rub the heatsink or use the heatsink to rub the sandpaper? Am i making any sence? lol

btw.. Did you do the 90 degree rotation? I heard from another guide it's best to do it in 1 direction

You put the sandpaper on a flat glass, then you rub the heatsink on the sandpaper.

I do a 90° rotation... but I will rotate back towards the same position in the next 90° instead of letting it go in a circle. Having this rotation gives you that extra shine!

Hmm.. im not quite sure what you are saying. Let me see, after rubbing it the first time, then turn the heatsink 90 degree and rub it. After that turn it another 90 degree which makes it a 180 degree turn and eventually a 360 degree?

but for AMD proc....or intel 478...can die if din handle carefully...

of coz use the heatsink to rub the sandpaper.

No, this is what he means:

First, lapped it to the north, then go to the west, then go to the north again, then go to the west again, and so it continues like that until you've satisfied with you're lapping job.

Do it times & times again...

I hope that explains...

Hmmm.. Ok when im lapping it to the north, i move the heatsink up and downwords on the heatsink. After im done with it, i turn it to the west and start moving left and right?

I lapped my processor but abit hard since it's small and hard to hold and it's light so we can't expect it to apply force to the sandpaper itself.

Yes, that's what i'm trying to explain earlier...
Glad that you've understand the north west explanation even it sound funny...

I just lapped an IHS of a Pentium D 820 just 1 hour ago, love it when i could see the copper IHS!!!

But not mirror shine though, as i just use - 600 - 800 - 1000 - 1500
Malas to buy a 2000Grit sandpaper...

I did the lapping in non water condition lapping, scared if it would spoil the processor if i use water...

Now, i'm going to lap my Pentium D 930, hope to see some nice temps improvement...
