Ok, so the other day I cleaned the dust out of my case with a can of air. Before that, my cpu fan was extremely loud, like a wind turbine with a high pitched whine. After I cleaned it, it was as quiet as could be.

Now today, I woke up and my entire case was vibrating so bad I could feel it in my computer desk. I pulled the side off and felt the CPU heatsink, and the whole thing was vibrating like crazy.

I tried shutting off the computer for a few minutes to let everything stop moving and tried turning it on again and got the same results. It's not loud itself, but it is making parts of my case vibrate and make noise.

I wasn't the one who originally built this computer. It was my fathers, but after he passed away my mom gave it to me, as she didn't need it. The cpu is an old LGA 775, Intel Core 2 Quad Q6600 2.4GHz.
Here's the weirdest part, I tried looking up my specific Fan/Heatsink model, and it doesn't seem to exist. It's a CoolerMaster B10478-33CB-4CP-L1. I found other B10478 models, but none of them match the look of this one, and the other models are meant for servers.

I guess my main questions are this:
1. Is there a way to fix this? Or should I just say screw it and buy a new CPU cooler?
2. Will the vibrating cause damage if I continue to use it for a few days after I order a new fan/heatsink?
3. How do I have a cooler that doesn't exist?

Just look for a LGA775 air cooler. Air coolers are socket specific, not motherboar or CPU specific. Also, check the modern ones, as many 1155 and 2011 coolers can be mounted into a 775 socket (just look at the specifications).
Other option is to keep the heatsink and replace just the fan (there is plenty of fans in the market, of all sizes).

If the vibration is too strong, it can cause other problems. If you can survive some days whitout it...

About how your actual one died, with time and use the fans start to acumulate dust, and to get loose on the shaft. But the dust was restraining it.

When you removed the dust, the fan becomes unbalanced, and because it was already loose, it get even more loose, and in some time fails.

It is...

It is very common that an old fan dies after some clearance.

Yea, I think I'll just have to let my computer sit for a day or two and order a new one off newegg. Thankfully it's an older socket and the coolers are cheap.

try removing the fan and running it when not screwed in ,see if it still vibrates
if so this method i have found to be effective.. (if u don't care about the fan)
drip motor oil into the hub after removing (be generous),jiggle the fan a bit ,then run it after connecting the power.
because the oil is non conductive ,it wont harm the electronics when the fan runs and sprays some drops of oil
again test for vibration when unscrewed AFTER running the fan for about 10 minutes
if the problem persists ,strike the hub with some force a few times in the center while its running.

imp---it is preferred that u use another source of power ,like an old charger rather than the mobo headers..
--keep the heatsink exposed to a breeze at all times
