Very loud noise on startup after Tags: CPUs Boot Power Last response: October 17, 2012 9:58 PM in CPUs Share litwicki23 October 17, 2012 7:50:00 PM Basically when I boot up I can hear a strange noise. Sounds like a fan losing power or slowing down. When I get into Win 7 Its quiet and normal. The noise is gone. This only seems to happen if the pc is left off for quite long and I boot it up in the mornings etc. Any idea what this could be? pc: Sabertooth Z77 I7 3770K 3.5 8gb ram Msi Gtx 680 Twin Frozr Be Quiet Dark Power Pro 1000W More about : loud noise startup jay_nar2012 a c 109 à CPUs October 17, 2012 8:48:52 PM When a fan goes slower it usually gets quieter as less air is being moved and the fan's motor is spinning less fast. You sure your temps are fine, i think it can be normal for some systems. phyco126 a b à CPUs October 17, 2012 9:58:26 PM Typically fans and what not spin up really fast when the PC is first turned on, and then will quiet down as the PC boots up.
