I'm looking for a 50x50x10mm blower for an AOpen mini-PC. The
existing fan's sleeve bearings performed as expected and expired well
before they should have.

I've searched ebay and the web to no avail. Does anyone know of a
source of small blowers (less than or equal to) the above
dimensions? It has to be 12v and I would prefer it to have the third
sense lead as it's temperature controlled.

Thanks in advance!
