3 pin fan power cable splitter?

[Starfury_2260]

I've got 4 case fans in my computer, and they're annoying because I had to hook them up to the power supply and they dont stop running when my computer goes on standby. Is there any sort of splitter I can use to connect them all to the 3 pin connector on my mother board? Does it even have enough power for 4 fans? And no I dont want a fan speed control thing, I'm looking for a cheap solution.
