Well it appears the 3-speed fans antec uses are not keeping my case cool enough on medium setting, and high setting is just to damn loud. Finding quiet 120mm fans that have an average amount of cfm isnt to hard, I got one for my cpu, but I need one that pushes alot of air and won't make you go deaf. Any ideas?

Yate Loon or Nexus medium speed fans are both very good. Most "quiet" fans are not going to have the airflow of the Tri-Cool on medium.

Question though, medium is quite a bit of CFM, maybe you need to look at airflow and cable management?

Scythe D/E fans are good too (though can't really run them on anything other than 100%)

coolermaster's old fans are also very quiet and push quite a bit of air (like 18db at 43CFM)

brian...all my cables are rounded... they block nothing. Look at my rig... 8800gtx, quad core cpu, 680sli with 2 giant heatsinks running sli ram at 1066mhz (2.3v), this thing puts out a ton of heat when im in a game. And I only have one exhaust fan really. I have my cpu's 120mm fan pointing up out the top vent (there is a small gap between the vent and the fan and the tri cool on the back vent). 1 tricool on the upper intake and one is mounted in the empty 5 inch bays to draw in air on push it over the ram and motherboard.

Usualy my pc can handle elevated temps but lately after WoW has been running for 4+ hours, it just gets to hot and the video driver keeps crashing untill the computer is turned off for about 20 minutes.

Hmmm, do you have the optional fan on the mobo heatpipe? How old is your mobo? Have you de-gooped your chipset heatsinks?

brian, yea because my cpu heatsink sits high, it didn't provide any airflow for the chipset so I ended up strapping the fan that came with it on. I didn't yank anyones heatsinks off though. I belive what was overheating was the memory, but after pointing a fan on it, it didnt stop it as it didnt remove heat, just blew it around.

Has had some good reviews and seems to pass quite a bit of air.

This is currently the best in my opinion:

120mm SilverStone FM121 (White) Dual ball bearing Case Fan + 2400rpm Pro Use - Hi End

Approx Fan Speed: 800 - 2400 rpm

Fan Airflow: Max. 110.03 CFM

Sound Level: 17 - 39.5 dB

If your video card is overheating, get a PCI slot exhaust fan and put it right under your card.

I did that with mine and it dropped the temps dramatically. It pumps out twice as much hot air as the fan on the card itself.

I want a fan test I can understand and emulate like how far It will blow a ping pong ball,

I don't own an anemometer

I actually use a 92mm nexus fan to bring air under the video card into the "pocket" the card draws air from. Remember though its because I have blow its hot air out and around that the card is cool, but the case gets hot. All my heat sinks are doing what they are doing, and now I am relying on one fan to suck it all out pretty much and the p180b is a full size case.

Kam.. it looks like it should beat out my tri cool at the same speeds for noise.

BTW the tri cool at max setting pushes 73CFM at is 36dba, incase anyone had a suggestion but unsure of comparison. :)
