    Molex to 3pin fan connector?

    Do these exist, and if so, where can I buy them?

    My case has molex connectors for the fans. My power supply comes with a useless manual fan controller card, but it only takes 3pin cables, so I need both male molex to female 3pin, and male 3pin to female molex (unless my PSU sneakily has a 3pin connection, which I can't remember).

    Thanks for link chuckskull as I thought they couldn't be purchased.

    I got some with the Sunbeam Rheobus I bought.

    I bought one of these fairly recently too. I have yet to use it though, as I'm a bit concerned the fan won't run at full speed if it draws power from the motherboard instead... Will it?

    Motherboards should give 12v unless it's throttled back by the bios etc.

    Should run at 12V as chuckskull says.

    The only thing that you would want to watch out for is if you were running several high-powered fans off the one motherboard header, and exceeded the wattage that the MB can provide (the motherboard specs sometimes state the max wattage per fan channel that it can handle).

    I checked the manual - my old Asus A7V333 fan connector would burn out with one of the Thermaltake 80mm Smart Fan (can't remember what they're called) but the newer Asus or other motherboards should be ok.
