I have a few questions about whether I should get an additional 80mm case fan for my computer. When the room gets warm (above mid 70s F), the computer gets a little hotter that I'd like (47-48 C) as it is always running under a high load. My case had a CPU duct, but I removed it as it wasn't in the right place for my board- it pointed somewhere between the far edge of the CPU HSF and the rear I/O ports.
The duct grille is perfectly drilled and spaced for an 80mm fan to be stuck there. I was going to stick one there but I recently built a unit that had 3 80mm case fans and each one of them was louder than my entire computer is. The only difference is that those fans aren't RPM-controlled by the motherboard and mine can be. Would those little fans spinning at 1500-1700rpm instead of the full 3450rpm make that much less noise? My 120mm and 80mm front fans makes little to no noise- I'd like to put another 120mm in there but the grille is not big enough for that.
So what do you think? Would it be noisy or not? Would it really help that much? Taking the side off of the machine lowers the temp about 1 C or so.
