Paul, in regards to mounting a fan to help keep your
1541 disk drive running cool, I have a couple of suggestions.

 1.  The head alignment problem is due to poor design of the
     disk drive.  There are no sensing switches that sense the
     end tracks and slow the head servo motor.  Instead, the
     head is slammed into a physical post to limit its travel.
     That is why the head does not stay in alignment for any
     period of time, not because of heat-warpage.

 2.  If you still are looking to put a fan in the disk housing
     you might try one of the ones powered by a "Hall-Effect"
     motor.  They usually run on low voltage DC and do not generate
     any RFI noise that might trash your disk.
