[comp.sys.atari.st] Mega 2 Fan Question

bks@tango.eng.ohio-state.edu (Brian K Smith) (02/11/90)

 I have a mega 2 with PC speed installed, and one external SF314 disk drive.
When either disk drive is accessed the fan in the mega slows down...
Is this a normal condition? Should I check my power supply? Could it have
anything to do with PC Speed?
 Thanks,
  Brian

My Mega 2 does this too.  Did it when it was new.  Still does it now.
I take it to mean marginal power supply and heavy current draw by the
motor for the drive.  So far, I have no hardware additions.

Anyone else who knows better have comments on this?

My Mega 4 does this too, and as far as I remember, it's done it since
it was new as well. Of course, now I have a bunch of stuff attached
inside it... No external floppy drive though.
