ATX Case Cooling Fan
gman Oct-30-01 02:15 PM
I have a dedicated space for a 4-pin case cooling fan in my mid-tower ATX model. What should I get? I will be running an AMD Athlon Thunderbird 1.4 Ghz and already have the Dragon ORB 4900 RPM for the processor. I have seen models with thermal sensors, ball bearing construction, etc. Any suggestions? What is the difference between 60mm, 80mm 120mm, etc.? I also have TTGI's 320W power supply installed.

CFM (cubic feet of air moved per minute), RPM, type of bearing, noise, expected life are other considerations. If you want to monitor the fan speed with the motherboard, get a 3-pin fan that will plug into the motherboard (instead of a 4-pin which plugs into the power supply)--if the motherboard supports case fans/fan monitoring.

I use 80mm fans for most cases and that is what most cases that have a provision for case fans specify. I am currently building three 1.4GHz Athlon computers. The cases and case fans will be exactly like http://duxcw.com/digest/Howto/buildcom/socka/1.htm. The CPU fans will be Thermaltake Volcano 5's. They will not be overclocked. Larry

Hi Larry,

Thanks for the info. and if I wasn't so lazy I would have read my motherboard book and discovered it for myself.

Again, muchos gracias!
