[TenTec] Hercules II fan noise

[Bob Good]

Greetings Steve,  I have operated a Herc II for the past 16 years.  I seldom 
notice that there is even a fan in the unit.  Only in heavy "contest" 
operation do I hear it and I don't recall ever hearing what I would call 
"high" speed.  I run my amp right up to the red led output.  No mods and a 
9420 supply.  Now there is a beast that could use a fan.............Regards, 
Bob
