i have tested a few C2D seems to me that my e6600 a lot hotter than others
Upon checking found out that my IHS is a bit concave
maybe is time to do some lapping to get better temp
warranty void no problem coz c2d not much value in 2nd hand market now
too many thread selling brand new only rm700 to rm900 only

wat do u guys think !

here is link lapping done by XS members : http://www.xtremesystems.org/forums/showthread.php?t=121077

I have only lapped my Swiftech Storm G4 waterblock....but for proc haven't liao......

If you feel its really concave then its worth a shot, I know I would. However, do ensure that is the main cause of your heat problems, ie. is your HSF hot to touch? How hot is your cpu at load?

Dunwan!!!!


if the proc is concave, the hsf wont be as hot as it should be. reason? the contact between hsf and ihs is poor. the only way to know is using coretemp or intel's TAT. there's no other software that can read core temp as accurate as those software..
using thermal probe also wont solve the mystery since the position of the thermal sensor does effect the result..

Would love to see your results lapping it rlhc. Mine's apparently convex instead concave (lucky me) but would be considering doing that too. By the way, if you know where to get sand paper of 400, 800 and 1200 grit, do let us know

I suggest you lap yours if your IHS is concave and you're getting excessive temps. I did and my load temps dropped 5-10C (depending on what clock speed) at the same voltage. Using the stock Intel cooler.

almostthere, you can get the sandpaper from any hardware shop.

Err...
Won't it void the warranty?

**Stupid question below:
Lapping won't cause electrostatic kaa?

But then, do you lap procs with running water?

oh yes indeed - no more warranty.

of coz the warranty will void

anyway, i hav done it on my old skul p4

you sure in various grits cos the darn hardware shop seems to be blur about this and shows me only a 400 grit and a 800 grit set. Need 1000+ grit for finishing leh

just got myself 400,600 & 1000grit sandpaper
going to do lapping only after i change to a new mobo next week hehe....

indeed! If ur h/w shop doesn't have higher grit then go to another one lor. i used 800, 1200, 1500 and 2000. Didn't get a mirror finish though. Took too long. Will post pics later. You should start with 400 as it'll be much easier.

Just tell them u need 1000+ grit ler.... go to other shop if the one u asked doesnt know

lucky my E63 does not concave else i'll join u.. well.. good luck bro..

sadly in Melaka, em Hardware shop owneers are damned n00b about this. Nevermind, there's always ACE Hardware in KL to drop by when I'm around

That looks great.Minor finish huh?

IINM, you can always look at the Sandpaper for the grit number...

I think all brand of sandpaper has the grit number on it right?

or maybe you use a too advance english
here in butterworth, penang (not the island) also selling like ketupat at raya

mine here is

swallow brand
water proof
abrasive paper
silicon carbide 2c
xxxx - aw

xxxx denotes the grits
here have from 300 ~ 2500
