Anyone ever tried underclocking?Many motherboards and processors can just as easily run under a rated speed as over a rated speed. As many processors expel alot of heat into the ambient air , it requires the use of big heatsinks and fans which equals , lots of noise.Now for an audio enthusiast noise is a nightmare in my pc case. So underclocking it will reduce heat thus enabling me to dump the big heatsink and fan.I dont use this pc for heavy use with complex tasks and mulitasking, just internet use , word ect and high quaility music. i have a Intel Pentium 4 660 "LGA775 Prescott" 3.6GHz (800FSB) processor with HT Technology. Can anyone give me any advice before i decide to do this? thanks.
