Looking to upgrade my front 3 case fans to the new corsair ml120 fans(non fan), but these new fans require 4 pin connections I believe. My current fans plug into a little splitter in the case, but all ports are 3 pin.
I don't think I have enough room in my mobo for all 3 fans, even if I did I don't want all the cables trailing throughout my case to different ports.

What I am ideally looking for is a cable that plugs directly into power supply(evga p2) and has multiple connections to plug the fans into. Similar to sata power cables for example.

I don't really know if this type of cable exists and what it would be called, does anyone know?

TIA

If you get a molex (standard 4 pin pc power) to fan splitter the fans will run at full speed constantly.

If I was doing it, I'd probably use a fan controller, or something like http://www.ebay.co.uk/itm/NEW-Gelid-Solutions-1-to-4-PWM-PC-Case-Fan-Splitter-Cable-/222547997416

That gets power from the molex cable, but plugs into one of the fan headers on your motherboard, so the fans will vary speed depending on your motherboards fan speed profiles. The fan headers on the motherboard can only draw a certain amount of current, so I'd avoid anything that just a splitter

A fan hub would do the job: https://www.amazon.co.uk/s/ref=nb_sb_noss_1?url=search-alias%3Daps&field-keywords=fan+hub

I use a NZXT Grid but only for 3 pin fans

Plugging them directly into your power supply will make them run at full speed with the associated noise. If you don't want that you'll need a fan controller.

If full speed is fine then something like these would be what you're after:

4 pin fans can be plugged into 3 pin ports - so long as the 4th pin can safely overhang.

A bit concerned about a 3 pin splitter though - I'd guess it only connects the tacho signal from one, otherwise they would conflict - and it might stretch the capability of a single header

2x6-pin to 1x8-pin is fine. 1x6-pin to 1x8-pin is questionable.
