Here's another alternative you might want to consider.
The NZXT Grid
is a 30watt rated 10 port 3-pin fan hub. It has no capacitor or anything like that, like the modmytoys PCB does, BUT it does also have the tach (rpm) signal active to all 10 ports instead of just one. No idea why so many of these hubs do that, but that was really easy to fix, and that made it ideal imho for use with a fan controller. Rather than reinvent the wheel, here's my post from the NZXT grid thread ...

Is the rpm (tach) signal wire split to all 10 ports in this NZXT hub?
If it is then this is basically useless to use with most fan controllers because the rpm speed inputs from all of the fans will corrupt the signal and the fan speed will not be correctly reported to the controller. Even cheap 3-pin fan splitter cables will only have all three wires going to one of the fan plugs, and just the 12v and ground to the rest.
If, as it should be, only one of the 3-pin outputs has the rpm signal wire, then which port is it? Unless you are going to connect fans to all 10 ports this is need-to-know info, but looking at it and the manual I'm not seeing it anywhere.
I bought two of these thinking they would be useful, but now I'm having second thoughts. I definitely don't want to have to cut the rpm signal wire on all the fans but one just to be able to use this hub with my fan controller.EDIT:
I found my multimeter and found out for sure that all 3 inputs are output to all 3 pins on all 10 of the ports.
That's a HUGE FAIL on NZXT's part imho, but what could be done about it ...
Soooo, I took the two screws out and removed the PCB from its cover and took a small pair of wire cutters and snipped the rpm prong from all but one of the 10 output ports.
Here's an 'after' pic of one of my Grid's with 6 fans from my 360 monsta attached to it ...
Also worth mentioning, as you can see from the images above, the NZXT Grid has two white LEDs that light up the three small slits on its cover. It gives it a pretty nice look even if it is something that's most likely going to be mounted out of view. The cover also helps keep any unused port's prongs out of the way from accidentally shorting anything out.Edited by Unicr0nhunter - 3/11/14 at 7:45am
