Please Help!!!!!

I have just purchased a antec 900 case with a coolermaster aerogate 1 fan controller but when I try to connect them, I noticed that they have different pins.



I have tried looking for 3pin to molex connverter but to no avail.

All stores claimed no stocks.

What should I do?

I neither resides in the states nor canada.

A fan controller with 3/4pins usually plugs inline with the fans like those on the side cover you can normally plud onto the board. The 120s in the 900 use the 12v standard molex type you plug into optical and ide hard drives there. There are reducers available for 12v to 7v like the one seen at the link here with the 3/4pin type adapter. http://www.pccasegear.com/prod2433.htm

Thanks for the reply.I have learnt something from there.

But is the antec 900 molex a male or female connector?

Do I need converter for this end?

The standard male connector coming for ide drives plugs right into those. With supplies seeing more then one 12v rail the extra molex type plugs needed will be there for the twin 120s in the front, one 120 in the rear, and the 20cm top fan.

I run an extra 120 on the side cover here that plugs onto the board as well as the Zalman CNPS-9700 hsf used. All you do there especially made easy if you are running sata not ide drives is making sure the supply has the 4 extra plugs.

Just think of having an extra 4 ide drives added when looking at the harness on the supply. The larger 600+w models will usually provide the few more you may need. Those will simply plug right into the female molex connectors for the fans there.

So I suppose I need a 3pin to molex converter for the fan controller.

Would the built in antec tricool fan controller default speed settings make any difference on each of the fan when connected to a controller?

Or would I need to set them to high spped for each of them in order for the controoler to work in a wider range?

I never played with the small adjuster on the 120s that come with the case here since I want those going full speed at the normal settings anyways. The cpu cooler came with it's own and the 120 on the side cover was simply placed there as an additional exhaust for repelling dust along the side of the case here.

The desk used has a compartment where the entire case is out of sight when the cabinet door is closed. The confined area is one reason why the 900 seeing twin 120s in the front for intake was noticed immediately when first seen.

With a 12v to 7v molex to 3'4pin conversion there you would simply leave the fans's adjuster at the normal and reduce or increase with the separate controller. Having an adjuster on each individual fan however allows you to experiment a little to see what works the best for you.

Strangely, for the highlighted line, I have read that if those small adjusters were set on low with the fan controller, then you will never get them to go higher on the low setting because that would be holding you back.



Now my question is, is that correct?

Cut off the molex connector on the fans and splice the cables, then do the same for the fan controller cables and then wire the red to the red and black to black then cover with tape or heatshrink, works like a treat.

With each fan seeing it's own small two position switch more or less rather then being like a volume control you would have to leave those at the high or standard setting. The addon controller you use will then have the ability to see the fan run at the max or reduce the speed by voltage control over all connected.

The fans included in the 900 are all 12v there while others with the 3/4pin type connectors usually going to the board are 5v typically. The controller should be rated for 12v however while still being able to reduce to 5v slowing the fans down. Basically that's what a controller will do for you there. The switches on each fan act like reducers so they are not running at full speed all of the time.

You can chop up and splice wires together as one means of tying things together like taylormsj is commenting there about. But then you are also stuck with any mod like that or would have to order replacement fans to see the case restored later. The controller still has to be rated for the 12-13v range since that is straight 12v being fed to the fans there.
