hi all-

I'm looking for some 140mm push only fan recommendations, there will be 4 fans on 2x280mm HWLabs GTS XFlow radiators (front intake and top exhaust) in a push only configuration .

It seems like noctua NF-A14 may be an option?

Not sure about PWM or not, would I have to get a controller? I do like the idea of variable speed based on noise/perf. ratio

Will be cooling my current CPU (platform upgrade in 1-3 years) and eventually 1080ti GPU

Loop order is res-pump- CPU-GPU-rad1(top)-rad2(front)-res

Thanks for the help!
 
I recently bought some of the Corsair ML fans and couldn't be happier. Super quiet, rock solid chassis, humongous controllable range, great looking lighting (if you want that.)

The only downsides are price and the fact that they must be PWM controlled; the magnetic bearing requires the steady 12v to operate. I would not use these non-controlled; at full tilt they spin stupid fast.

I currently have low/med/high switches on my Antec 900 fans and like that flexibility, but am not sure what PWM control involves. Do you have a hub board? Is it controlled by software? Sorry for now knowing much about the PWM fans!

It depends!

There's two types of continuously variable fan control. One is voltage control, which you use for 3-pin fans, and it's just what it sounds like: the fan is controlled by varying the voltage fed to it. The pro to voltage control is that virtually any fan (even most PWM/4pin fans) can use it. The cons are that voltage control isn't as accurate as PWM and generally the control range isn't as large; a voltage controlled fan can't usually spin as slowly as a PWM fan.

PWM stands for Pulse Width Modulation. PWM fans are 4-wire, as they have a 12v input as well as a separate PWM signal (0-100%) which dictates their speed. They're typically a little pricier, but have a wider controllable range and are more accurate than voltage controlled fans.

The first thing to figure out is what fan headers yourb motherboard has available and which control methods it can use. A 3-pin header can't do PWM, and may or may not be voltage controllable (via BIOS or software.) A 4-pin header will always have PWM capability, but may or may not be voltage controllable.

Inexpensive fan hubs are available in either flavor and some even convert one control method to the other, so you can probably accomplish whatever you want regardless of your motherboard's header count.
 
I bought 5x noctua nf a14's, once I get my fan controller together I'll see how well it all works!
