PWM Fan controller

stumpy6 · 6 Dec 2015 at 20:49

I'm in the process of changing my 2 x 360mm Radiators for 2 x 480mm. But have come up against a problem. (Case Phanteks Ethroo Primo)
I currently run my radiators 6x120mm (4 pin) PWM fans off my motherboard (Asus RVE) 4 pin fan headers. Now I'm left with 1 spare, as the CPU_OPT is used for a Phanteks PWM controller for 5 X 140mm case fans.
So this is where hopefully you guys/gals come in. Can somebody point me into the right direction for a PWM (4 Pin) fan controller that can power 8 x 120mm fans.
Thanks

You could use a couple of 2, 3 or 4 way splitters, a PWM splitter (phobya do one) or buy a dedicated fan controller like the Grid+ V2.

The AquaComputer Aquaero 5 LT appears to be the best that I have found.

There is also the Aquaero 5 xt which is the lt with an LCD screen that mounts in a 5.25 drive bay, but it is a lot more expensive.

Stumpy did you find a decent controller, I'm looking for the same thing. Need 4 pin controllers/splitters but only seem to see 3 pin controllers everywhere.

Any 4 pin fan be controlled by 3 pin voltage control.

If 4 pin PWM fans are plugged into a 3 pin hub then are they all going to be set to the same speed (i.e. no individual control?)

Depends on the hub. Grid+ v2 has 6 individual channels that can be controlled separately.

Aquaero 6. I have 22 fans on mine and they are all PWM.

This. Unfortunately they are pricey but they are excellent pieces of kit.

Worth noting that the Aquaero 5 - whilst good - has one PWM header and three 3-pin headers. The Aquaero 6 has 4 four PWM headers (that also support 3-pin fans). The 6 also handles more power per channel - which is more helpful for voltage controlled pumps and fan arrays.

Thanks for the info. 22 fans :eek:

what case are you running?
