Getting ready for the bios tweak, is there anything else I need to know? its an EVGA 8600gts, custom cooling and all, with a case side fan blowing on it, would maybe a custom fan on the top of the card blowing down on it help with temps?

well the stock 8600 fan on the evga models suck in sair that pass over the gpu and it blows out tword the back of the case if you have any open air slots in the back of the case it will bleed some heat..any after market cooler would be better but the stock one isnt bad volt modded and with a lapped cooler my idle temps were 43ºC load was round 70ish..so not bad at all. remember with an after market cooler to get ram sinks or your card will burn out but if your strapped for cash or dont feel like doing the work take some 2000 grit sandpaper and lap it works wonders.

I know i sound like a noob right now, but what is lapping?
NVM, i found it, sounds like a good idea, does it really help that much?

I hit 743 core,1589 shader, and 1050 memory. Im not idling so great, its at like 48c now....I'm going to try experimenting with some xbox 360 fans left over from another mod project, those suckers push the air! One thing, when I remove my cooler from my evga 8600, will I need thermal tape or will the paste I have do the trick when I replace it? Also, I'm going to go for the pencil mod, I'm getting another identical card just for emergencies lol.

Hi,

I was wondering if you could point out what resisters I need to pencil over on my XFX 8600GT XXX. Heres a picture of the back.



This was the best I could get out of my camera, If I need to take a picture of a different location, please tell me. Thanks

Ok, heres the other half of the card, everything should be visible between the two pictures. I'm gonna shut down and pull the card out if this doesn't cover it.
