The top and rear exhaust fans of my tower (this) have started to rattle terribly. I've never had to fiddle with fans before, so I'm wondering whether I should try to fix (lubricate?) the existing fans, or replace them with new ones.
as always, you start with the free fix and see if it works - if not, you proceed to spending money
so, open the case, clean the fans (dust/dirt can actually unbalance the blades, causing a rattling), make sure no wires are coming in contact with the blades (another common cause of noise), and if all is well, remove the little sticker and put a drop of machine oil in there.
if it works, then you're done - if not, then you have to replace. Looks like the fans are 120mm so a pretty common size - just make sure to get the same end connectors or you'll have to do some crimping/soldering.
