Actually reading about the Corsair AF140 it seems to be brilliant. Quiet however it tops off with a bit less blow than other noisier fans I guess. Other Corsair fans also seem to have been well reviewed and user ratings are nice too but I’m aware that the Air 540 fans have been met with criticism.
Worth trying out for $70 or is there an obviously better choice that you can support with experience or benchmarks?
I currently have the following arrangement:
3x120mm Akasa Apache Black PWM (front intake)
1x140mm Akasa Apache Black PWM (exhaust)
1x120mm Akasa Venom on CPU
The CPU fan header goes into a PWM splitter (again, Akasa) which then drives the Venom and Apaches.
Airflow/pressure is _exactly_ neutral. No air comes in or out of the top port or the back grilles. The entire thing is built to respond to CPU temps (PWM splitter on CPU) and I could not be happier. When it's idle, it's silent, and I sit on the floor next to my rig so I care a great deal about how the term "silent" is thrown around. Under load, my OC'd 2550k never hits more than 75C in ambients of 28C.
I thought Akasa were a cheap, no-name brand which wasn't worth my time. I was very, very wrong indeed - the Apache and Venom fans they produce are awesome. PWM splitting is the future - it's a fan controller you don't need to controll. If you were lookikng to add 2-3 fans up in the top slot, I'd recommend a Swiftech splitter and some high RPM/static pressure fans on the front intake, as you'll need them to avoid negative pressure and a dusty inside.
