God help me. My fan is driving me crazy.

My fan constantly slows down and speeds back up and I dont know why. When it does this it's very load and vibrates my desk, and it gets annoying very fast.
I dont know why this would randomly happen unless the fan is F'd.. I don't have other fans so I cant plug another one into the same place and see if its another hardware issue or something.
I cant imagine this is BIOS related or whatever because I've had this computer for two years and this only started like 2-3 days ago if that.
This computer is giving me a lot of problems recently and I'm really getting sick of it :\

That a front case fan ? What is it connected to ?

Yes, it's in the front, at the bottom, in front of my hard drives...
I'm not actually sure where it goes as when I took the entire front plate off the case and cleaned the fan, I gave up trying to follow the wire after it goes along the side of the case, and into a really right space somewhere in the front between the hard drives and front structure of the case itself. Looking in with a flashlight and trying to wiggle the wire didn't help any, I still couldn't see where it had gone and I think the wiggling didn't do anything because of the tightly secured cable management that was put in place by the technician that put the thing together in the first place.... I can try to look another time when it isn't 4:30 am and dark as could be...

I asked about it's connection because it may be connected different ways and that could cause the problem as well as fan itself. Do you have any program that can show you fan's speeds, like SpeedFan for instance ?

The fan connects to a part of the wiring harness that had been tucked away under my hard drives, I think it just goes to the power supply from there...

I just downloaded SpeedFan and I really don't see anything out of the ordinary, but I really don't know what ordinary should be for my situation. I don't see a drastic fluctuation in RPM or anything that would seem strange...

It will not show up in Speedfan if it was connected directly to PSU or over a controller in the case. It's essential to find out what it's connected to.
