Hi all,

I'm a first time builder who has bought all the components for a new PC and would appreciate some help wiring the fans up. I have:
- Lian Li PC-B25F case. This has 5 fans ...
* 2 x 120mm (1200 RPM) fans on the front panel
* 2 x 140mm (1000 RPM) fans on top of case
* 1 x 120mm (1500 RPM) fan on (upper) rear panel of case
* PSU is mounted on (lower) rear panel of case

- P7P55D-E pro motherboard
- Noctua NH-D14 (comes with 2 x radiator fans)
- i5-750
- Seasonic X-650 PSU

(I also have other components RAM, Video card etc too).

My motherboard has the following fan headers:
- CPU_FAN (middle of the board)
- CHA_FAN1 (adjacent to CPU_FAN)
- CHA_FAN2 (extreme bottom right corner of board)

I was wondering what the best way connect all of the available fans to my Motherboard would be (which should be connected to the motherboard and which to the PSU)? I have a y-splitter cable so that I can wire both of my Noctua coolers fans to a single fan header. Will my motherboard be able to power these OK? (The fans look huge). Also, the motherboard has Asus's Fan Xpert technology built in so I'd like to make sure everything's connected to use this if possible!

Thanks in advance all!

Hi kataru,

I would suggest Noctua fans (using the splitter cable) to CPU_ FAN, one of the front fans to CHA_ FAN1 and the other front fan to CHA_FAN2 ( these three fans would be controlled by Asus's Fan Xpert). The upper rear fan to the PWR_FAN and the other two fans could be connected to the PSU.
