Fan Bearing Gone Bad, Warranty?

I have a TX750W that I purchased from Newegg on 2/14/2011 about 3 1/2 years ago. Now the power supply comes with a 5 year warranty. Recently it sounds like the bearings in the fan have failed and now its making a LOT of noise. Will my warranty cover a new fan?



If not how hard is it to replace said fan... it is just an awful sound and I need a solution ASAP!

Thanks!!!
