rotron caravel fan used in DEC and other cabinets

[Tom Hunter]

Hi Paul,

At first I have replaced the bearings in the original two 10" fans in the
top of my LAB-8/e rack hoping to reduce the noise substantially.
The new bearings did not noticeably improve the noise levels.

After a few days of suffering through the noise I decided to replace them
with modern and quieter versions which move the same volume of air.
As I am in Australia I changed from the original 115V fans to 240V fans
which meant I no longer had to use the large 240V to 115V step-down
transformer in the back of the H960 rack.

Regards
Tom
