Cool it!

I have always preferred Class A amps with properly designed heat sinks that cool sufficiently without and added fans (which might fail, possibly cooking your amp).

I have one system that runs two mono Class A amp, each of which puts out around 400 watts in heat just sitting idling (they actually put out less heat when working hard as some of the current is used in outputting sound).  They run hot as Hell but were intended to run that way, and have been for more than 30 years

The problem with this sort of heat sinking is that it tends to be pretty large physically. The ones I use are 16.5" high and weight more than 100 lbs. each.  I would get nervous with any amp that would turn to trash if a fan motor failed and you didn't notice immediately.

HOT air rises so always have ventilation on top of unit.No need for a fan.

"Hot air rises" goes to show why Geoff has the highest post count... 

Sorry to hear about your broken nose, anachronism, must’ve happened when I turned right too fast.

I’ll have to say I enjoy reading almost everyone’s point of view.  There are some that insist on creating a war of words.  This is aggravating. I too have posted too many crazy contributions, after having adult beverages. At times I will ask questions, that I know the answers to, just to get opinions.  I always like to learn.  No one knows it all, although some will have you believe they do. I always like to read what Raul has to say, although I don’t always agree.  I have several favorites, but they will go unmentioned.
