From: Louis Cornelio
The fan I removed from my System Saver IIgs is the Comaire-Rotron Sprite
SU2C1-- 'C1, not 'C7. Actually, out of the case, it seems very quite. Much of
the noise seems to be rattle from contact with the plastic case of the SS ...
I put down some foam weatherstrip along fan-case contact points and that
did the trick! I guess there was a bit of vibraction or something. The fan is
stil audible, but only slightly from the air.

Below are specs, ordering numbers, and prices for several possible System
Saver IIgs replacement fans. As you can see, the noise numbers for the sleeve
bearing fan models originally used in System Saver IIgs are not bad. The catch
is that the numbers are for new units before bearing wear begins to increase
noise. If you replace your fan, a ball bearing model is recommended.
