I was reading the reviews of the Biostair A870U3 motherboard that I bought and I saw that it only has 1 system fan port, but my case has 4 fans with an optional 5th fan. Is there any way I can get all 4 to work or am I screwed?
Any help or advice would be greatly appreciated.

Here are the specs of my first PC build:

Windows 7 Home Premium SP1
AMD Athlon II X4 645 3.10ghz Processor
GeForce GTX 560 Ti
Corsair 600w psu
BIOSTAR A870U3 AM3 AMD 870 motherboard
Antec Three Hundred Illusion Black Steel ATX Mid Tower Computer Case
2 x 2GB RAM 1333mhz
1 TB Hard Drive

You just need this adapter and it can hook up to 4 fans!

Hey I just built a new gaming rig with that same Motherboard, while it does only have one system fan port, the rest of your fans can be plugged directly into the power supply. I have 1 system fan into mobo, 1 cpu fan into mobo and 2 case fans directly into the PSU. This mobo allowed me to install windows 7 from a usb onto a SSD pretty easily, the only complaint I have with it is where the CPU power cable is. I have a bottom mounted PSU and the connection is all the way directly on the opposite side of the board, so if you have a bottom mounted psu, be ready to have fairly bad cable management.

The only minor issue with plugging the fans into the PSU as opposed to the motherboard is that you can't control the fan speeds.
