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

i did it on my p4, dropped temp by 1C, not that significant but 1C is life and death, hehe! 1000 and 2000 grit paper, with the pin side hooked to a static free sponge to hold them there.

got my 400,600. 800,1000 at Ace mid valley, 1200,1500 at my localold-skool hardware store in klang, and 2000 in SS2 hardware store(dunno the name)double storey one.

So..................

Has anyone started lapping their C2D?

What about the threadstarter?

Have you lapped you're IHS of you're C2D?

hmm.. few noob questions from me:

how do we lap the surface? any guide?
we start from what type of sand paper and finish with what?
when do we finish the lapping process..izit when we see the mirror-like surface?

izit the same with HSF surface?

not yet,no mobo now to test
need to take down the temp before & after lapping


start with 400 then 600,800 & last 1000grit

erm... nelza_ax,

nice lapping there ... mirror finish...

I tried lapping my heatsink before, but never thought of lapping my processor. maybe i should do that.

the prescott i got at home have really abnormal temps...

err...

noob and stupid question ...

What will happen if the processor got wet during lapping. i mean the pins.

Thanks.

IINM don't think anything will happen as lons as there's no electricity running through the processor...

But just make sure that you don't submerge the processor liao...

just make sure dry up the processor before plug it back...or...I can't imaging what will be happen...

But, what will happen if some water got through the capacitors under the processor?

Will it make the processor dead?

err...I am not sure...never try before...maybe will short circuit gua...

maybe you wanna try.... just kidding lar...dun blame me if you really try and spoil...

Nope, i am not gonna do that, i love my Pentium D 930 liao...

Even if i've wanted to do lapping on my processor's IHS, i'd think about doing it hundreds of times before i do it...

***Paiseh, up until today, no one answer my question about pulling out the LGA775 processor IHS...

Anyone know how?

I've been wondering, if i take out the IHS, then put a thermal paste on the core of my processor, then smack em with my XP120 without putting the IHS back on top of the core, would it make a lot of difference than using together with the IHS?

You have so many post counts. You should already know the answer di right? If u still dont know, you can always use google.

If i know the answer, then i won't be asking here liao...

I've tried googling around, but i can't seem to find an answer to that question...

really?

http://sHawTY.justgotowned.com .........
By the way, removing IHS seem like an extreme move...I dont dare to do it...

I LOLed

Btw, after you removed the IHS, mean no protection to the bare core.
Installing heatsink directly will just break the bare core. Assuming you are installing those clip mounted heatsink.

You will need to add some protection and ensure that the pressure of the heatsink is just right for the bare core.

Water block will be easier a bit and less dangerous though.

Ya. U got a valid point there...I am sure HSF like XP-120 which use retention clip will had high change to break the core. I notice too much pressure applied on the IHS when installing it..

I've googled around in yahoo and google, and a lot of forums about pc overclocking...

And what i get is a "NO"...

Guess i won't be doing it...

Hmm, might at least lap my processor IHS...

Do anyone know, does Pentium D 930 also uses the same IHS that is used on C2D processors?

IINM, C2D processors uses Copper IHS that is covered in nickel plating...
Does Pentium D 930 also uses the same recipe?

http://www.overclock.net/1020872-post9.html
there you go shawty..
reading material for you..

I know that...
I've done my research here and there, and what i got is a "NO"...

That's why i said in the last post that i won't be doing it...

All i've wanted to do now is lap my Pentium D 930 IHS...

do tell how the lapping goes...

I want too, but i don't have any digital camera...

Can someone borrow me their digicam?

But the lapping doesn't go well like what threadstarter get for his ninja liao...

I want the base of my XP120 to be mirror shine like the threadstarter's Ninja base...

You've posted in too many threads di. This is not my thread la

Err, what are you talking about man?

I think i've posted in the right topic, this topic sure discuss about lapping processor's IHS, this is what i'm gonna do, but not now, i'll wait until my motheboard is back into my hands back then after that i'll lap my Pentium D 930...

This threadstarter is not neoxz and he didnt post pics of his scythe ninja....DUH

Now, this thread(given url below) threadstarter is neoxz and he posted pics of his ninja

http://forum.lowyat.net/index.php?showtopic=363027

I guess you dont even know what ur posting leh.. just spamming only

Oopps...
My mistake, i've mistakenly post that thing in this E6600 topic...

But still, i'm here for discussing about my Pentium D 930 IHS lapping...

Haiz.. ur so blur la

this processor how to sell ?

if you want buy other

I have just lapped my e6600 ES.
And what a great suprise, decrease 5 degrees compared before lapping.

I noticed that my ES is not flat at all before lapping, that's why i choose to lap it.

The result?
Lovely.

PIC! PIC! PIC!

no pic no talk

You want pic, you belanja me one digital camera la...

bro sHawTY, you own many thread pic wor... better buy a cheap cheap camera and take some photo to fit their hunger lar... btw...me too...wish to buy a camera but hard to fork out the money to buy... buy other PC item...very easy to fork out money...wonder why...

hahaha, bro shawty spend all his $$ on his latest pc parts oredi gua... neway, ppl now juz trust their hp camera so not many ppl got digi camera oso.. dat remind me of need to buy new digi camera oredi... lol...

lapping proc ihs..? will we be able to check our proc batch no after doing that??? i mean v can check it by the label on the box or on the ihs rite??? i've thrown my box, but how u know if its flat???

AFAIK, even P4 uses copper IHS
no doubt Pentium D will be copper too.
Surprisingly, what you asked what you said could be found by google.

Anyway, nice work on lapping the E6600.

Nahh, u won't be able to check the processor batch unless u take a picture of it before u lap it.

How to know it's flat or not?
See how the thermal paste spread lah, put a bit of paste that is on the size of a rice, then fit a HSF on top of the processor, then see how the paste spread out.

That's one of the way to identify either the IHS is flat or not.

Thanks sis.
Got very large differences between before lap and after lap.
A 5 degrees decrease is a very large drop.

Dont forget that sHawTY is using an E6600 ES. So there is no more warranty for it.

Bear in mind that lapping your processor will automatically void your warranty. hehe

Anyway, sHawTY your result is impressive.

ES no warranty no problem

then a...when u all use ori intel hsf...just change their pin to skrew with spring...to make sure that ur hsf very2 ketat lio..huhu then u see the diffrent...okiesss

mine lapping done but still not good enough
will do some touch-up when i change another mobo soon
temp drop around 5 to 6 degrees

wAnna lap mine too.. where u guys get those sand paper? : )
Put inside fridge to o'c after lapped it, anyone tried it b4??

This post has been edited by yehlai: Apr 24 2007, 08:42 PM

you guys are getting my hands itchy...prob gonna lap mine too. how good of a temp drop can one expect from lapping?

sorry if this is OT but since it's about lapping still so i guess it's ok

wat about if i lap my xp90, is it ok to do that?? not the full copper type. the surface is already nicked, can even trace the layout of my sempron die on it

why not for you to lap it ?

As long as you got some time to spend, go ahead
XP-90 comes with copper base and it is nickle plated.
