Hi. I have the Enermax NAXN 450AGT PSU. I would like to replace the fan for Airen Redwings 120. Am I going to have any problems with the fan connected in the motherboard? Or should I plug it into the PSU fan slot using only 2 out of 3 holes on the fan connector? Will the above mentioned Airen regulate its revolutions correctly while plugged directly in the PSU fan slot? Thanks for answers and apologize my bad english
