Putting together my new system and have a couple questions. The case (raidmax smilodon) has numerous fans but there was 1 spot on right side for an additional fan close to the hds mtg area; if installing a fan here should it blow across the hds or pulling out the air. Also the ma770 ds3 makes ref to a northbridge fan plug/socket for n bridge fan but there is one mtd on the case in direct line with the cpu/n bridge that is also pulling out the air, would that be ok since it don't plug into the n.brigde fan socket. Currently there are 3ea 80mm and 2ea 120mm fans plus a 120mm on the psu, is this enough.One last item, if u start the pc before u install the os should it make post sound or not, thanks.
