Connecting molex fans to a fan controller

macmodder · 26 Sep 2011 at 14:32

I have an Antec 900 (which is really growing on me since I painted the insides black and added so better cable routing) which has 4 fans, all of which have molex connectors. They're the stock Antec 'TriCool' fans which have low, medium and high settings, but I've decided I want to be able to control the fans without taking the side panel off, so I'm thinking of switching them all to high and getting a fan controller (probably a Lamptron FC2). Fan controllers seem to use 3 pin connectors, but I'm not sure which is male/female with 3 pin, so can someone point me in the right direction for an appropriate molex to 3-pin adapter?

Tri-cool fans come with three pin fan plugs anyway ?

Not the ones in my case, or I lost the adapters perhaps. I gather any one of the connectors can power either of the other two on the adapter you linked to?

You want these:

Akasa AK-CB423-ADPT 4 - 3pin adapter cable

Using fans with molex connectors there's no RPM sensor wire so if you have a fan controller with an RPM display it will just read 0.

The ones that Surveyor linked would be appropriate for your needs, although they are tad ugly.

I am tempted to buy connectors, pins and wire myself - I used to be quite good at that sort of thing at school, so maybe I'll do the instead, at least I'll be able to pick my colours, cable length etc to fit

Different wire's susally mean different voltages.....although i guess if you aren't selling your system then there's no need to bother about that.....

I probably won't sell my system as is, I usually cannibalise them as I go, and certainly wouldn't sell home made parts. I am going to have to do some serious googling though, I'm pretty rusty at this sort of thing.
