Lapped My Quad Core

[Thawaxshop]

Lapped my ES quad last night. Man this is one of the worst chips ive seen.

Before

400 Grit

600 Grit

Final 2500 Grit

wow that is shiny lol.

 

[Hiks]

amazing job mate :worship:

 

[Toxcity]

Woah! You have yourself a mini mirror!

Nice work dude!

 

[FarFarAway]

Nice job dude. Still keep thinking to do mine

 

[deathwish]

that HS looks better in the reflection than real life

Deathwish i think im going to have to agree with you there!

 

[chudley]

Another sweet demo of lapping on this forum, definately gonna have to give it a go sometime.

Nice job, however, ive seen less flat intels myself This one actually went through on the edges before the middle was exposed.....

I didnt even get up to 600 grit on it

 

[Rastalovich]

Ouch exposure >.<

Nice lapping btw, and the hs does look better mirrored

Nice and shiney, but was it worth it

What sort of temp drop did you manage to get?

noob question guys!

what does lapping a cpu mean?

is it something to do with cooling it better :worship:

 

[WC Annihilus]

Lapping involves sanding the CPU (and/or cooler) to make it flatter, allowing greater contact between the CPU and cooler, thus giving greater heat transfer and lower temperatures.

@equk: Next time you quote a post with a pic, would you mind changing it to a link? Kinda uses up space and makes loading a bit slower

I just thought I'd post this as there seems to be a trend, where people lap their CPUs IHS. I've not seen anyone say it makes anymore than 1°C-3°C difference. It also voids the warranty (3years on intel).

So my question is: is lapping worth it?

Why Lap?

Due to the machining process, just about every heat sink will have a rough surface. To the naked eye it may look flat or even feel smooth, but there are microscopic groves in the surface. These groves will trap air between the heat sink and the CPU, and cause a poor transfer of heat.

Thermal compound is used to fill these groves and help transfer the heat from the CPU to the heat sink. Just like air, thermal compound is something else that the heat has to pass through to get from the CPU to the heat sink.

We lap the heat sink to make it smooth, allowing us to get the best possible contact between the CPU and heat sink. Even after lapping, there will still be grooves for the air to be trapped in, but the grooves will be much smaller, and cause less of a problem.

I've not bothered myself as the IHS is still there (not the same as removing+using a shim).

Seems to me some people are thinking: I'm hardcore/experienced 'cos I can sand down metal

,\.,

 

[FarFarAway]

Yep simply samnding it down to a very fine grit making it flat and increasing surface contact area

 

[NoL]

Flat enough you can get away without TIM!

omg

i didn't realise it involved that

geez, thats dedication for you - fair play

don't think that is something i would have the balls to do

Try it on an old / dead cpu, it's really not that much effort (although on a top end cpu it takes some guts lol). Also if you use 600, 1000 then Tcut followed by a really light abrasive like copper cleaner you can get it done in half the time.

yeah in theory it does sound straight forward to an extent

but i think this will be one thing i will be giving a miss, i will sort a new cooler out for mine, that is as about far as i will be getting atm lol :worship:

Lap the base of your cooler
