Hello
I installed a fan and it works, but the LEDs aren't working, it has a 2 pin connector for the PSU and another one that plugs into the motherboard (pretty sure this is molex). I can't seem to find a 2 pin connector for the mobo, I have checked the motherboard manual but to no avail, any help appreciated. :)

Check the hots/grounds in the manual. You can use a two pin connector on a 4 pin header if and only if the header and wires match up (look for colors). All of the fan power headers on this specific motherboard are 4-pin.

The molex, is what connects straight to the PSU, the 2 pin is the fan speed control that goes to your motherboard. Most fans, you dont have to use both-its one or the other. If your fan is spinning, and the LEDs not lining up, its either this is one of the fans that require both, or your LEDs are burnt out.

Well it is brand new so it shouldn't have burnt out, unless I got a bad one. Is there any way that I can get it connected to the motherboard. It does require both for the LEDs to work, because it is spinning just fine. Thank you for your advice!

You can contact the manufacturer to make sure the it works with that PSU. What PSU are u using? It is possible your PSU doesn't have the cable for it.

Are you certain its a 2 pin? Most fan to motherboard cables are 3 or 4 pin. . .and Im not finding any adaptors for a 2 pin.

ok just found the fan, it is indeed a 2 pin, which is a rarity on fans, even rarer on motherboards, and as far as I can tell, no adaptors are made for it. Some solutions Ive seen online, and only do this if your confident with working with electricity, is cutting the wires, and wire tapping them into a 4 pin molex, one to the ground the other to the +12v cable. What may be easier, and Ive done this before with some proprietary computers, is locate a 3 pin fan controller on your motherboard-and cut the little plastic piece on the end of the 2 pin conenctor in half, between the wires, and on the fan (or the system power LED switch) and figure out which one of the pins on the 3 pin is positive, and which is negative, and connect the two now single connectors, to the appropriate pins.

The pins on the mobo are:
+5v
Cha Fan In
Cha Fan Pwr
Gnd

Would it work if I connected it to a 4 pin connector by cutting the plastic barrier off?

the led doesn't need to be connected to the motherboard ,especially if it only has 2 pins ,just splice it into a 4 pin Molex plug ,I think new motherboard only have 3 or more ,for bios /3rd party programs temp/speed monitoring

My answers are my opinion only,usually

so if I cut the 2 pin mobo connector and put those into a 4 pin molex connector that will work?

yes lizard, you can cut the 2 pin, and either connect it to the positive and negative pins on the motherboard fan connectors, or onto a molex connector from the PSU. It should work.

Wish I had seen this a couple years ago, when you were having the issue, but for others researching...  A 2 pin fan connector will connect to 3 pin mobo jack if you align the key on the plug (little vertical plastic stripes).  It should snap right into the 3 pin jack using 2 of the jacks pins.  .
