WOW! Testing of Fan Setup in P180

[Anomalous]

I tried flipping the top fan so as to make it an intake, and it actually brought down my CPUs temps about 3 degrees C, but It also brought up the temperature in my SLI setup about 3 degrees. I guess all the hot air the intake was shooting off of the CPUs Heatsink had to go somewhere. BTW both fans were set to high.

What is the rated CFMs of the 2 x 120mm x 25mm tricool fans and the 120mm x 38mm fan down below?

Thanks

120x25= Low>1200rpm/39cfm/25dBA -- Med>1600rpm/56cfm/28dBA -- High>2000rpm/79cfm/30dBA
120x38= Low900rpm/36cfm/17dBA -- Med>1200rpm/48cfm/23dBA -- High>1500rpm/60cfm/28dBA
I just dont believe these are accurate specs by Antec. Specifically the dBA ratings. They are all noisy by my standards even on low speeds. The 125x38 vibrates like a civ. El Cheapo BB fans imo.

I am pretty sure the cfm ratings are not close as well.....I agree they ae noisier as well than what they are rated

ok after changing the top fan as intake, my 3.2 pressy OC to 3.9 is down from 43C idle to 38C idle. 5C change is really nice. Gota test load now, i couldnt run 3.9 in my p180 with both fans as outtake. GPU temps are the same.
