So my system currently has 15x 120mm fans and 4x 80mm fans. I am finding it a challenge keeping a tidy system. I am currently using 2 fan controllers to control some of them, but I am wondering if there are any other sort of devices that can control a large number of fans and keep them running at full speed.

Im open to suggestions on how to deal with this number of fans, as at the moment I seem to have endless daisy chains of wiring.

Thanks :)
 
Good lord. Nineteen fans is quite an achievement. 3 pin, 4 pin, molex or a mixture?

The obvious thing to suggest is either (many) Y connectors or splicing them directly. Probably running two fans off each channel on the fan controller.

I have to be the first to ask, what on earth do you have nineteen fans running for, and can we see a photo please :)
 
:O i nearly blasted tea over my screen when i read that!

i have 8 (excluding the psu) which i think is more than enough... 19?! that's lunacy!

pics, or it didn't happen :D
 
Watercooled i7 920 and 4870X2 in MM Ascension.





6x 120mm front
3x 120mm opposite site of front radiator
3x 120mm roof
3x 120mm rear
2x 80mm side of mobo trays (both sides, so 4x) you can see them in second pic.

So there you go, 19 fans :)
 
I like that very much indeed, thank you for the photos :)

Triple radiators particularly lend themselves to splicing the wires together, solder the positive wires together, the negative wires together, and cut off two of the rpm sensors, then braid/tape the lot together. This leaves you with one 3 pin to deal with for the entire radiator.

I think its going to be a combination of Y splitters and splicing for the rest. if you have some pwm fans then you can run at least three of them from the cpu fan header using a cable ocuk sell.
 
I recently spied some little PCB's with six 3 pin fan headers on them, powered by a molex, Fan Power Distribution Board. They are only a fiver or so, so I might have a try with one of those. The only thing I dont want is for 3 of the fans to be full speed and for 3 to be on 'silent' mode, im sure ive seen that before and its not quite what im looking for.
