[TenTec] Centaur

[Ken Brown]

don't use the Centaur much due to the fan noise.  What mod. (size) Papst 
57 CFM do you use?  Would like to use the Centaur on ssb too.

How is it that it is okay to replace a 100 CFM fan with a lower air flow 
model? Do the Taylor 572Bs not require as much air flow as 811s? Or did 
Ten-Tec build it for RTTY 100% duty cycle? What happens if you use it 
for RTTY after you put in the lower flow fan? Or is that just something 
you never want to do?
