Controlling 4pin fans w/ fan controller

August 21, 2011 10:03:13 PM

Hi. In my case, I have Antec fans. Each fan has a 4pin power molex (male) & a switch for Low/Med/High. I bought this AeroCool X-Vision fan controller hoping to control the Antec exhaust fans' RPM
http://www.newegg.com/Product/Product.aspx?Item=N82E16811999230
I believe I need a certain type of adapter to connect the fan controller 3pin wires (male) to the Antec fans. Are any of these what I need?

All of the newegg links come up as "bad request". It could be a problem on newegg's end, or you could have posted the links wrong. Could you repost the newegg links? (all 3 if you can, but need the first one)

I think you may be disappointed.

The Antec fans are controlled by a switch that reduces the voltage, slow, medium, high.
The fans do not have the third yellow wire which is the speed sensor wire.

So, when you use one of the adapters you listed, it will connect the fan to the front panel controller, and will adjust the speed of the fan. But, you will get no speed information since the fan does not provide it.

It seems to me to be simpler to just adjust the antec fans to a speed of your liking and forget it.

geofelt, if usable will this give me speed information? Link Depot POW-ADT-3P4 Power 4 pin adapter to 3 pin fan adapter http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I don't think so.

A fan will have a + and - power pair to operate.
Some fans will also have a third wire which gives speed information. If your fan has a molex plug with two + and - wires plus a third(usually yellow) wire, it may have a speed sensor. The adapter shows only two pins, not the 3 which would be needed to transmit speed info.

Thank you geofelt. You saved me lots of headache & time. If you've time to spare, I'd really appreciate it if you can link me to a site selling the proper wiring i need to get speed information. I am not electrically-inclined at all. Again thank you so much. For now I bought this anyway http://www.svc.com/4to3ad.html

A good site for fans and cooling products is frozencpu.com

To get speed information, you need a fan that can supply it. I don't think you can rewire a fan to get that info if the fan does not come with it in the first place.
