I recently upgraded my pc, the problem now is that the northbridge fan is too loud on the Nforce3 ultra chipset. I am looking into replacing it with a larger northbridge heatsink thats fanless like this http://www.newegg.com/app/ViewProduc...118-214&depa=0 Anyone used these will I have cooling issues, the PC is currenty overclocked. Its amd64 3500+ winchester core 90nm overclocked from 2200mhz to 2400mhz via raising the frontside bus from 200mhz to 218mhz. System runs nice and cool right now. I don't do too long of high cpu intesive stuff the occasional video encoding or like 30-60 min gaming sessions.
