[Amps] 3CX800 and blower

         Does anyone have any idea how this (250 deg C seal temp)
might relate to air exhaust temperature?

         I found the following in a March 2001 RadCom
review of the Acom 2000/1000 by Peter Hart:

"When the exhaust temperature reaches 90deg C, which it can to under 
hectic contest conditions or RTTY, the blower engages a higher 
speed,  but, even in this case, the increase in noise level is not 
particularly great."

Of course this is for a 4CX800 instead of a 3CX800.
The display appears to range from 10-150C.

Does anyone know what the actual limit is for the ACOM
to display:

"FRONT TUBE EXHAUST TEMP TOO HIGH"
