The above link is the noise my mic picks up. Where is that annoying sound coming from? How can I eliminate it out of my vocal recordings once and for all?
Well, without knowing what equipment you have it's really kinda hard to know. It could be a furnace, an air conditioning unit, the next door neighbor's dryer, your equipment, or perhaps what this guy is recording

My room has a million sounds. The light, the computer, my router, my cable modem, the refrigerator in the kitchen, the furnace, any outside noise, me farting, and God knows what else.
Here is a quick test (assuming you had your microphone plugged in).
1. Unplug everything and record silence (from your soundcard). Do you hear it? If no go to #2
2. Plug your mixer, pre-amp whatever but do not plug your microphone just yet. Turn the output to 10 or whatever the highest is if you have a mixer and record. Do you hear it? If not got to #3
3. Plug in your microphone and record. Do you hear it? Probably yes!
This little short test will tell you that every component in the chain will add a small amount of background noise. However, your room noise is the biggest noise. If it's your room then you have to play with your gain, Mic fader, and the master fader to try to minimize your S/N ratio. That's signal to Noise ratio, in case you didn't know what S/N meant.
If you hear the noise way before then it's probably your audio card. However, I don't know if you have an integrated soundcard or if you own a MOTU audio device, or perhaps you are using a firewire or usb device.
Happy hunting.
