The fan of my Arctic Cooling Freezer 7 LP doesn't work when I connect it to my DG45FC motherboard. It spins up a very (very) short while after power on and then stops and the computer doesn't continue booting.
If I plug in my old CPU fan that came with the CPU, everything works (the motherboard is not broken). If I plug in the CPU fan in another computer, it works (fan not broken). It just seems like the combination of the two doesn't work.
I tried setting "Automatic Fan Detection" to "Always" in the BIOS, but it didn't help.

The problem might be a compatibility issue with the desktop board and your third party fan. Also remember that using a third party fan or cooling solution will may void the processor warranty and it may damage it.
I recommend to use the original fan and heatsink that came with your processor
