hmm... good quality?

I was looking for new fans to go with a case that I'm purchasing and I came across these
http://store.yahoo.com/svcompucycle/4ledfn-blu-33.html. They don't seem to be a name brand. Do you think it really matters? The price is really good and in my opinion $ 6 - 7 is more that I'd like to spend for a fan.

bumpage ... someone has to be using generic fans out there?

it's a sleeve bearing, so lifetime is shortened I'm pretty sure.
plus, usually cheap products inflate their ratings, so you may not get as much airflow as it says and it may be louder than it says.

but in the end, it is still a fan, so it will still move air.
I have not personally used them, but my advice is go ahead and try them, chances are you won't be horribly displeased

ah... i didn't notice that it was a sleeve bearing... in fact, I have no idea what the difference is between sleeve and ball bearings... maybe someone mechanically enclined can explain it?

Fans that use sleeve bearings usually use an oil-impregnated brass sleeve as the primary bearing for the shaft of the fan opposed to ball bearings. Ball bearing fans typically last longer than sleeve fans too.

but you can make sleeve bearing last as long ... just do anual servicing to the fan.. some WD40 can work wonders

WD40 or any oils will attract dust and leave a stickier build up of dust then the norm

How is this a problem? Usually, the bearing is covered by a rubber plug or at least a sticker anyway.

Because you don't want a sticky substance as a lubricant. Something like silicone-based lube or something with teflon in it would be better.
