Hi guys, recently purchased an aerocool predator x3 case and struggling to connect the leads which come from the speed control dials for the two main fans it comes with. I have connected the fans themselves to the motherboard and power supply. However, there is a set of three wires from each fan speed controller dial at the front of the case. Each wire has a 2 pin adapter on the end. It says "fan A1" "fan A2" and "fan A3" on each wire for fan A for example. So there are three separate 2 pin adapters which are on the same bundle if that makes sense. Where do these adapters plug into?

Thanks for any help you can give me!

It appears that at least the rear fan has a tandem 4-pin molex adaptor and a smaller 3-pin variable speed fan connector. It may be the same for the front fan, I don't know. Plug the larger 4-pin moxex connector into a 4-pin female molex connector from the PSU and plug the fan(s) into the smaller 3-pin speed controller dongle. Rinse and repeat for channel B.

You really didn't think this thru, did you?

Thanks for your answer. I did already plug it into the PSU so it works its just the speed controller that I can't hook up anywhere. On the last picture from that link where it shows fan A1, A2 etc there is an adapter underneath each one for it to go into. Is this what you mean by the speed controller dongle. Where does that come from as there is no such adapter that came with it or coming from the PSU?

The larger molex conn. plugs into the speed controller and the smaller of the FAN connector(s) plug into the A1/2/3 or B1/2/3 small connector(s).
Actually, the speed controllers on the case panel are intended mostly for additional fans. If you automatic speed control it would be better to plug your existing case fans onto the motherboard fan headers, if your mobo has them, and set fan speeds from the BIOS or the supplied motherboard utility program if it has one.

Thanks again. I think what threw me was that each fan has a 4pin molex and I'm guessing that is if you don't want to use the fan controller? In which case you use this and plug the fan into the mobo?
