help!

which of the fan convector on OCuk do i buy for converting a Molex connector fan to a FanMate2 speed controller that came with my Zalman CPU cooler?

the FanMate2 controller has 1 3-pin input, and 1 3-pin output.

so i want to power 2 cheap Molex connected fans. which product do i buy from OCuk?

You would need a 4pin-3pin converter like this to connect the fans to the 3pin connector. If you want two fans on the fanmate then you would need two of these converters and also a 3pin splitter like this.

as you know, the fans' molex connector is in parallel with another female output.

so can i wire the 2 fans like this? will it work?

[note, the 3-pin to male/female is the first link provided by mark1]

edit: the Corsair HX 620w don't seem to have a 3-pin fan cable, looks like i'll need to buy 2 3-pin fan to 4-pin molex?

The configuration in your pic above will work. Like you said though, you will need a 3pin - 4pin adapter to allow the fanmate to connect to the psu.

To save the hassle though you could try doing the 7v fan mod on the fans to keep them at a constant lower speed. This link should help: http://www.bleedinedge.com/guides/7volt_mod/7volt_fan_mod.html

that looks to be much cheaper and simpler.....

thank you very much. i'll use the "7v fan mod" instead.
