Fan connections On mobo


Apr 25, 2009
Hey guys, I've just ordered the parts for my new build. I was just looking at the specs of my motherboard (GA-P45-UD3P) and I saw this:

Internal I/O Connectors

1. 1 x 24-pin ATX main power connector
2. 1 x 8-pin ATX 12V power connector
3. 1 x floppy disk drive connector
4. 1 x IDE connector
5. 8 x SATA 3Gb/s connectors
6. 1 x CPU fan header
7. 2 x system fan headers
8. 1 x power fan header
9. 1 x front panel header
10. 1 x front panel audio header
11. 1 x CD In connector
12. 1 x S/PDIF In header
13. 1 x S/PDIF Out header
14. 2 x USB 2.0/1.1 headers
15. 1 x IEEE 1394a header
16. 1 x parallel port header
17. 1 x serial port header
18. 1 x power LED header
19. 1 x chassis intrusion header

From what I understood I can only plug in 2 case fans on that mobo. If that's the case then I've got a problem. I'm going to be using a Cooller master rc-690 case and I'm planing on using all 7 fan slots on that case. Can anyone recommend me a fan controller (not the ones that burst into flames though :heink: )

The system fan headers are 3 pins headers that only monitors your fans and report them to the system, it's not critical if you can't connect ALL of your 7 fans to your board. You also have one "Power Fan Header" which is a 4-pin fan that you can actually control the speed of it. You can just plus all the other fans into Molex Power cables and you'll be good to go. I would recommend Antec Tri-cool fans, there's some 120mm ones and they have a little cable that lets you control their speed : L-M-H.
