When I start up my computer the fan get's pretty darn loud for little while, then stops after about 4-5 minutes, then it doesn't make a noise again until the computer eventually overheats. I can hear a small little whirring so I'm pretty sure the heatsink is still running fine. I can get more info like which fan and whatnot is making the noise later on, I just woke up and don't feel like getting around the desk, my setup is pretty messed up.

Could be a number of things making it louder. Not mounted tight and it rattles, a wire or something hitting the fan blades, Computer case and fans are dirty causing more heat to build up and the system ramps up the fan speeds more often. Sometimes just cleaning the fan is not good enough and you have to take it off the cpu and clean the layer of dust caked on the heatsink. I saw a old toothbrush in half and get in there scrub them clean and then blast it with a can of air. Be sure to cover your face and wear a mask that dust can make you sick.
