Hey I recently bought the Akasa AK-FC-03 Fan Controller Pro and connected it up to my power supply and the 3pin fan connectors. The display tells me what speeds my 4 fans are doing (around 2000) but when I turn the dial down to make them slower nothing happens on any of the 4 fans. The power supply and 3 pin connectors are obviously all connected properly because it tells me what speeds my fans are currently doing. Am I doing something wrong or does this sound like a faulty product? Is it normal that if 1 dial doesnt work then none of them will. I have 4 thermaltake 120mm fans connected to it and each of them are connected to my power supply properly.

Any ideas?

When you say each are connected to the PSU...? Doesn't the fan controller give them the power so the psu connection is unnecessary and probably over riding the controllers reduced voltage.
 
hmm.. Dont have a fan controller so cant say for sure, but i though the whole point of them was to cut down on wires and connections etc and allowing you to run multiple fans at various speeds through one power source...

Try a different fan?

I dont think having them connected to a molex etc as well as the fan controller is correct though... the controller controls the fan speed by reducing the voltage the fans get which slows their RPM.

Obvious... but, checked the manual?
 
Does your fan controller than use one power connector for its own display and a seperate power connector for fan power? This might be where you're going wrong..?
 
Connect your controller to your power supply.

And connect your fans to the controller.

In your first post you say you connect each fan to the power supply, (which i asume is molex) and the controller.

If not set up right what is controlling what.
 
When you talk about 3-pin leads, do they have 3 wires coming out of them (red/black/yellow) or is it a 3-pin connector with 1 wire (yellow) and your fans are actually powered off a 4-pin molex connector?

The fan controller can only worth with fans that are powered from the 3-pin connector. If you have both 4-pin molex (PSU type) and 3-pin fan header connectors then only use the 3-pin fan connectors and disconnect the ones from the PSU.

Hopefully that makes sense.:o

yeh i only got the yellow going to my 3pin fan connector which explains why theres no power when i take out the molex.

something else thats a bit strange is that i have the red, 2 x black and a yellow going to 4-pin molex from the fans themselves but theres also a smaller red cable stuck in with yellow and a red/black cable going into the same hole as one of the blacks if thats makes sense. This is how these fans came i've not modified them. theyre 2 thermaltake blue led and 2 red led fans.

is this cable the answer to my prayers? http://www.overclockers.co.uk/showproduct.php?prodid=CB-012-AK&groupid=701&catid=48&subcat=153
 
hang on i meant to say that the only cables coming from the fans themselves is the 1 x yellow in a 3 pin fan connector and a red and red/black going into a 4pin molex with a yellow, 2x black and a red coming out of that...
 
umm.... whut? haha

If the fans dont have a normal 3 pin connection then yes, that akasa cable may help, just plug the 3pin end into the fan controller and the molex end into the fan molex... I think.
