I always thought that sleeve fans were cheap and nasty, and ball bearing 
fans were the way to go.   However, sleeve fans run better for longer 
when strapped to a hot thing, like a heatsink.

The GPU fan on one machine packed up, so I got a fan that sits in the 
PCI slot and blows air straight at the video card beside it.  Not 
silent, but at 600 RPM its close enough.  And not touching the video 
card means more air movement etc.

I'd be careful lubing a fan inside a case - lots of rotation means it 
will migrate out along the fan blades if not restrained by something.  I 
have vague memories of someone peeling off a sticker from a fan and 
dropping a single drop of light oil on that side.  Only effective for a 
couple months.
