Hi. I only have one connector for an exhaust fan in my motherboard. Is there a popular maker of fans out there that designed an two fan exhaust (80mm or bigger) that only has one 12v connector?
All my power supply connections are filled btw. Thanks in advance.

You can bundle those cables together and plug them on the same connector on your board.

And if you're unable to find a 'Y' 3 pin spitter to bundle fan cables locally, there are plenty of 4 pin fans out there and any Radio Shack, Bestbuy, Circuit City type store should have a 4 pin 'Y' splitter that will split one of the already used 4 pin connections coming from your PSU. Both should be pretty inexpensive.
