|F||Front fan (pulls air out)|
|B||Rear fan (sucks air in)|
|1||4 pin CPU FAN|
|2||3 pin SYS FAN connector|
This case is a little odd as the front fan cannot be reversed to air flows back to front not the usual front to back.
How it’s wired up
- The front fan (F) is connected to the CPU FAN socket (1)
- The black/yellow jumper cable from F is connected to the display (D)
- The rear fan (R) is daisy chained on the F cable
- The black/yellow jumper cable from R is connected to the display (2)
- The CPU fan (C) is daisy chained on the F cable behind R
Note: This is based on the hardware I used for my Windows Home Server build and yours may vary somewhat. I’m not an expert on this! I spent a lot of time mucking around with it but if I’m completely honest I couldn’t tell you why this works better than other configurations I tried but it does. If I did this again I would try and get all four pin fans and things would be much easier.
The previous post shows the BIOS settings I’m using. The trick here is to set the fan controller such that the CPU fan is just ticking over and the other fans are off unless the temperature starts to rise.
