I just switched my CPU fan out for a new one. I thought the results were interesting so I thought I'd share.
I had this one:
Newegg.com - ZALMAN CNPS9500 AT 2 Ball CPU Cooling Fan/Heatsink - CPU Fans & Heatsinks
And I replaced it with this one:
Newegg.com - COOLER MASTER RR-LIE-L9E1-GP 95mm Rifle CPU Cooler - CPU Fans & Heatsinks
My average core temperature (idle) before the switch (with the more expensive fan) was 22 degrees celcius.
My new average core temperature is 24, only 2 degrees higher.
I thought the new fan would not work nearly as well, because of the price.
Thought I should post in case it could help someone save a few bucks.
BTW, my CPU is a stock Q6600 quad core, and it resides in an Antec 900.
