Fan going bad need help

[31 YNOT]

My right fan on my MBP is going bad, making a clicking sounds and when i restarted my computer it didnt even turn on for about 15min(0rpm accoring to my istat). If the fan speeds have to go up it sounds like my computer is gonna blow up.
Where can I find parts?
and how hard is a fan to replace?

Same exact thing happened to my unibody mbp I took it to the Apple store, and they replaced the fan. They called me and said the new fan didn't fix the problem. Now they're replacing the entire logic board, so replacing the fan might not work.

iFxit has a good guide to replacing the fan. I've had to replace a fan on mine before and did it through iFixit.
