Lapping the thermaltake big typhoon base

[[XC] leviathan18]

well yesterday i bought my TT big typhoon now some pics vs the stock cooler



now the pic of the awfull finished base



now how to lap it and have a nice mirror finish

first buy wet sand paper grits 360 400 500 600 1000 1200 and 2000

grit from lower to higher in one direction i.e. from north to south with the 360 grit then from west to east with the 400 and then repeat from north to south with the 500 and so on till the 2000

then buy rubbing compound perfect it II from 3M number 05973 and rub the base then after 5 hours the final result is this



hope it helps......

thanks to my friend UnG for the inspiration

wow, thats beautiful, nice work man

thx bro im so ******* tired xD

[Magnj]

wow...you better have your IHS off with that baby for prefecto contacto

[[XC] leviathan18]

im going to take it in consideration is there any way to put the ihs on again if i sell my cpu???

[dinos22]

good job

look at that base

if you guys have one TT big typhoon do this little mod worth the effort

[Major_A]

I commend you for taking the time to do that, but from personal experience it's never really worth it. You spent another $5+ and a lot of time to see maybe a 1-2 degree drop in load temps.

[[XC] leviathan18]

well everything for better temps

[Major_A]

True that. It does look damn good, it would be nice if they'd do that from the factory.

[Ugly n Grey]

Nice work Lev, you went from a chunk of copper to a mirror

i think a finish like that makes the cooler a lot more expensive...

the rubbing compound did all the magic when i finished with the 2000 grit i was scared it was still scratched so i remembered that i had this rubbing compound (specially made to polish car paint) that i bought for another project that is in hold (paint case guide) and give it a try one little drop of the compound and mirror finish... almost magic

well after running prime for 3 hours my temps now are 50 degrees load with the case closed and 48 degrees with the case open, from 53 before the laping (with the case open)

my spec is athlon 3500 @ stock newcastle


edit: room temp about 30°

[uOpt]

3 degrees down?

/me runs out getting sandpaper. Who needs bread?

[[XC] leviathan18]

if i open the case is 5° delta (im using stock fan) is pretty silent i cant hear it im very pleased with the results

I have one, I did it, I think it was worth it.

What's the point of lapping the heatsink when the CPU itself isn't really all that smooth? You have as5 anyway to fill in all the gaps.

[[XC] leviathan18]

i used as5 and if the base is smoother and well polished you transfer more heat...

[saaya]

beautifull!
thats the best lapping job ive ever seen!

[[XC] leviathan18]

thanks saaya sad i didnt had this for the XS GP .... well until next time hope to have better HW to kee up with ya guys

Nice job leviathan! After some burn in those temps should be high 49's. Maybe u should look into lapping the IHS (with glass to make it flat). U could also lap the die, but u should be EXTREMELY careful. Plus if thats running 24/7, u should make it run D2OL.

[[XC] leviathan18]

i tried to run D2OL but i had some troubles with it.... perhaps later i will read all the guide (im pretty lazy....)

lapping the IHS mmmm with glass???? care to explain me more???

i tried to give it a nice thin of as5 my temps are pretty good for my ambien temp and i have a newcastle you guys runing 90nm have better temps and more OC im trying to build some money for a 7800gtx and 3700 sandy

[nkcd]

It's beautiful....but

I don't see the point of using polish compond beside making it looks mirror finish AND negate the effect of lapping. The places where polish compounds filled-in should be for AS5 instead to transfer more heat. Polish compound would simply reduce the effect of a fully lapped HS. I've tried both, and without the polish compound, my temp was 4C lower at full load.

[[XC] leviathan18]

this isnt normal polish it has particles that acts like a higher grit besides i took a small hydro jet and cleaned the base

3M rubbing compound is designed to use with car paint at the final stages is a very nice thing

For some reason I remember reading that when u sand with glass, that it makes the surface much flatter. Something on those lines. Maybe I'll search google for this.
