ive Nforce2 IGP mobo and using its MX440 onboard graphic chip. I want to use passive cooling with zalmans northbirdge heatsinks instead of active fan. What do you think? I only OC fsb from 266 to 333. Is this solutýon works or crashes? And if it wont cool enough,are there any possibilty of damageing NB chip? Thanks for comments...
