Just lapped zalman 9500!

[goodie]

finally got the courage up to lap my heatsink,
temps before lapping heatsink were
39/38/33/38
i lapped my 9500 hoping it would sort out uneven core temps
unfortunately it didnt, must have a concave/convex CPU
GOOD NEWS
even though i didnt think i did that good a job, couldnt tell if it was flat because the only stanley blade i had was used & couldnt find any really straight edge
my temps dropped a full 4 degrees
35/34/31/34 my hottest core was 61 degrees (prime 100% load)
NOW 57 degrees!
just need to get the BALLS to lap my CPU!
EDIT: i forgot, my northbridge also dropped 3 degrees 46 - 43

that's very interesting....
It's very tempting for me because I didn't lap either the HS or CPU, I got a stable oc at 3.533 but my temps were too high (hottest core at 72c prime)

I bet if I did both the cpu and hs.....my temps would drop 10c.

It really is a bit scary though....I feel like the friction on the cpu is going to want to build up electric current.

Maybe one day

i thinking of doing my IHS, if i do i'll probably stick the black plastic protective clip back on & insulation tape it down around the edges, sealing it off?
is this a good idea?
anyone?

Decided to lap my Q6600 today, didnt bother with tape round the edge of cpu just clipped the black backing back on,
i did really good job, very slow movements using 400 800 1200 grit.
bit dissapointed in temps, difference between lapping my 9500 i gained nearly 1 degree & gained 1 degree northbridge drop.
temps went up first time i seated heatsink, reseated it & temps are more or less the same before lapping?
using zalman ZM-STG1 thermal grease

Dont really need to lap the hsf unless its got a bad bend in it, but lapping the CPU usually gives a lot lower temps, you can buy kits from some places. 800grit is where the performance gains generally stop.
