lolx...another ppl addicted after reading here...haha

hehe... you got extra sandpaper? maybe can sell some to me

how bout xp90, can it be lapped too?

can.. y not?

btw, anybody agree with the idea of spraying anti-rust to copper heatsinks? or even alu heatsinks. not spray at the base lah.. at the fins. if spray then won't get oxidised, but dunno heat transfer will get affected or not

Depends on you skill..if you can spray a super thin coat then the effect will be minimal. Don't bother for aluminium heatsinks-they form an ultra-thin oxide layer very fast which will do the same thing.

My lapped Thermalright XP90

For a first timer you did pretty ok. However you were not thorough enough with the higher grit sandpapers.

Hmm, I should post my TT pipe101 here. Can also do my TT silent boost.

any idea to improve? now holiday, got many time to play around

When you lap the heatsink you need to sand it till the marks from the last sandpaper grade you used are gone before you move to the next sandpaper grade.

I'm also on holiday, but often busy. If I have time I'll go a proper guide.

actually, there's 1500, 2000 and 3/0 ....something like that....but it's way too fine until you wont get the mirror shine.....anyway......i think your lapping still can be improved.....

2000 is quite hard to get in Penang, you have any idea where? I can find up to 1500 only in some of the better shops.

But anyway, from my experience, the eveness of the surface matters more than the finish. A shiny mirror finish with an uneven surface will perform much worse than a flat surface and a not-so-shiny surface.

butterworth here got one shop selling it, but I cant find the 1500 one. Actually I want to get 1000, 1500 and 2000, but at last found 1200 and 2000. think that there's a big jump, so didnt buy the 2000 one.

Even with 1500 I can get a mirror finish with the help of some metal polish. Have to wash the heatsink after that though. I'll do a guide on that, around or after CNY. Will be cleaning my heatsinks anyway.

Btw, if you want some decent 1500 I can help you get it. Send it over by normal post in envelope.

penang cant get 1500 and 2000??? i can find it in my area wor....
but i sand till 1500 grit only. then test it with a drop of water on the heatsink surface while is dry and press it gently on my flat glass to see the water all come out evenly from the side. then use some metal polish. and they are done.

b'worth where?

try going mak mandin
the row of shops after the football field houses 1 hardware shop
