@ Sandy - I bought 2000 for 35 bucks for a small sheet, 5k was for 75 bux ;)
 
ahh...lucky ones..

had looked all day but couldnt find anything higher than 2500 here in kolkata..

:'(..when can i shift to mumbai for good??
 
When I was going to Lap a HS I checked the modding forums and found that most people were using around 1200 grit paper - they said too much of a shine is not a good thing for cooling. I found 1600 grit paper and used that on my Thermalright HS - the result is attached..... before lapping the finish on the base of the HS was quite dull.

EDIT: Forgot to mention ... all this hours of labour for lapping dropped CPU temp about 1 or 2 C ONLY !! :D
 
^^ u mentioned something similar loong back :P lapping heatsink and getting a degree diff .. is this pic from then ?

yeah i remember reading in quite a few places that making the base too shiny isnt too good for cooling either

YUP ....same picture same information...... this HS is a Thermalright SK6.
 
well thats logical..:)

i read somewhere that the minute ridges and valleys existing under the base allow the thermal compound attain better contact between cpu hs and heatsink..as in that case it gets well spread and evenly distributed.

the other extreme case is a convex or concave base..where there is no contact at all..:P ...

so ur need to lap and its effect really depends on the initial condition of the hs base..

thermalright, as i've reas in many places, generally has excellent finish. so u done really need to lap..:)
 
Sunny, lucky dawg :P

BTW, my lapping project is yet to get underway. Cant find anything better than the f***ing shit Carborandum :@

Why dont you send me a set of sandpapers ? :D

Dropped my temps 2 degrees on idle and 3 degrees on load... and aah yes its a thermalright :D.
 
^^ some people have all the exceptional things happening to them..:)..joking

but i think you will admit some heatsinks respond better to lapping..like thermaltake..
