all about air cooling. here are some things i know about cooling pc.
--copper heat sinks are best for cooling processors,
--buy a casing with 2 fans in front of pc taking air in, and 2 fans in back of casing taking air out, your atx computer is designed for this,,putting a pedestal fan in front of the computer, keeping computer parts in a open area while operating messes with the natural airflow of system and supllies uneven air to parts of computer
--keep air ducks clean
--when installing a processor make sure the thermal grease on bottom of heatsink does not mess up,i know a lot of computer walas who actually wipe off grease before installing so that processor gets messed up in long term, for repeat business u understand..which is bad idea
--the less heat your computer gives out the longer the life
--i was getting heat problems with a 7300gt inno3d card and p4 3 ghz ht prcessor,,finally i got tired of it, researched the subject and bought a asus sis 671 moboboard which is known for generating less heat, bought a 1.6 e2140 which is also know for some,,
--And finally go to a computer wala who knows about this stuff, usually the local shopkeepers know nothing about this.
