geforce 2 gts oc'ng...

[Fro]

i have a msi starforce815 gts 32mb card. i found an old generic socket370 hf, cut it in half, lapped the bottom(i really dinged it with the dremel but fixed it in the end) used some generic frag tape. and managed to oc it to 235/395 and got 3300 3dmarks in 2k1

now i'm still using the stock hsf, do any of you guys think takign the time to lap it might help even more? i noticed that with the ramsinks i was able to oc higher than my previous 215/375. i just reall dont like pullin my pc apart constantly and i know the stock haetsinks are thin so i dont wanna risk ruining it for no reason
