Phanteks PWM 3 pin fan hub

Haven't heard anything about this on the forums really but I really want this to be released.

I don't even know fully what it will be called but its from phanteks and allows you to control up to 11, 3 pin fans directly from a single 4 pin PWM fan header.

Not entirely sure how it works but appears to use pwm from a motherboard header to alter voltage from the molex (built in version) or sata (external retail version) connector? Either way it works exactly the same as the pwm fan hub in the Enthoo Primo.

My interest is because I'm looking into buying a H440 but without front drive bays I am limited in fan control options and would like to use AF120 3 pin fans. I also want to avoid multiple fan connections all over my board headers and any rear slot fan controller options.

Below is an image of the retail model from CES 2014 but there isn't much more info other than it should be released around now.

Will OcUK be stocking these or get further info on their release date?

I haven't really seen anything like this anywhere else other than with phanteks at the moment and the ability to control multiple 3 pin fans from a 4 pin pwm board header is a big selling point to me.

Seen a similar one before which was custom built on a pub by a modder who's needs were very similar to your own.

Can definitely be done power-wise and seems very small and convenient

I have the one in the primo case but don't currently use it. As long as you have it connected to a PWM header such as cpu fan one, it will control 3 pin fans too, runs 6 fans as standard from the fan header, any more means you need to connect the Molex power connector. Fan speed is controlled by software such as Asus ai suites fan xpert.

It's a similar implementation to my original PWM converter circuit, which incidentally can do at least 4 fans per output transistor.

The single fan signal going through an NPN transistor, allowing the reporting of rpm feedback with the remainder switched through a p-channel mosfet. Done nicely on a proper PCB.

However it does seem to be missing the ability to modify the fan response of the first attached fan so a low power fan may run faster than it needs to.

I did wonder if Phanteks would bring something like this to market properly.

If anyone is interested and Phanteks don't bring it to market then I could be persuaded to design something.

I have been looking at driving large loads (several amperes) already and have a working circuit and bringing the two together should be simple enough.

I think it has been possible to get the basic looking model used in the primo direct from phanteks themselves. Ive seen pics of primo cases with two fitted and there is optional mount points on the mobo tray rear for it. As in only using 8 fans via the mobo headers ive never got round to trying the hub.

The original Phanteks notice for Enthoo Primo was with PWM fan hubs, but by the time they were released there was only 1 hub included.
