CM690 Fans

[skinnyq]

hey guys, I just bought the following fans:
2x Slipstream 1600RPM,
1x S-Flex 1600,
1x S-Flex 1900,
1x GentleTyphoon 1850.
I have a mugen 2 cooler, CM690-1 stock fans.
I really need your advice on where to put each fan, and whether to replace them with the stock fans, and if so where to position the stock fans
(in other words, where would it be most important to put the better fans and where is it less important). Thanks!

Re: CM690 Fans

I have the original CM 690 case where I'm using:

• 4 Aerocool Streamliner 140mm fans, 1000 rpm, 40 cfm
• 2 Scythe S-FLex fans, 1600 rpm, 64 cfm
• 1 Cooler Master fan, 1200 rpm, 40 cfm

Fan setup:

• 2 Streamliner fans on the side case, intake air for the video cards
• 2 Streamliner fans on the top of the case, exhausting heated air out the top
• S-Flex fan on the front case; intake air for the drives
• S-Flex fan on the rear case, exhausting heated air
• Cooler Master fan on the bottom of the case, intake air

I use a fan controller to run both S-Flex fans at 1300 rpm for less noise.
I tried using an 89cfm fan on the side case at full speed, ~ 2000 rpm, and this caused my highly overclocked N4660GTX temperatures to rise more than 10^o (C) while stress testing!!

If you need additional cooling for your video card, check out http://forums.tweaktown.com/video-ca...g-results.html, posts 81 - 91 and post 110 for my cooling results using an Arctic Cooling 92mm PWM fan with and without a cooling fan shroud.
