4 pin PWM advice needed

Mr_Moose · 19 Nov 2009 at 20:25

Hey Guys,

I've recently bought 2 120mm Akasa Apache fans to use as intake. I didn't realise they used 4 pin PWM connectors (i do now).
Problem I'm having is my mobo (MSI P55-CD53) only has 1 pwm header (CPU fan using it) and 2x 3 pin headers.
Can you advise if i'd be best going for the Akasa splitter

Code:

or a fan controller

Code:

or even just connecting the fans to the 3 pin headers and forget about the pwn function all together??
Any advice would be helpful as I'm new to all this and currently at a crossroads.

Cheers

The Akasa splitter works for me mate-both fans ramping up and down as required

-not ried it with 3 though but as power is taken from the molex it will be fine.

I was a little concerened running the CPU fan off a splitter cable but I suppose i'd effectively be doing that with a fan controller anyway, it'd just be bigger and have an LED display

Id just stick them on the motherboards 3 pin fan headers, pwm fans only come into their own when used as cpu cooling fans, either one on the cpu fan header or two on the akasa splitter cable with a cpu cooler that can use 2 fans in push/pull config.

I have those akasa PWN splitters running 5 fans and they work a treat! All ramp up and down no worries.

Before anyone asks how I got 5 fans off 3 connectors I have 2 splitters, with the mobo plug from 1 splitter plugged into the fans port on the other, daisy chained

Thats great to hear Phunky, been considering trying this myself, good to know that it works fine. Thanks.

Ahh brilliant, I'm glad someone's tried daisy chaining these. I remember a conversation where we agreed it should work, but none of us had tried it.

Shame none of my fans are pwm.

Im definitely gonna order another cable to try this, shame that the sharkoon se's i currently use are so expensive, £13.00 a pop and then another £16.00 for delivery from the only etailer i know that stocks them, but it would mean i could get rid of the two 2000 rpm intakes i use and the fan controller theyre connected to.
