How hot is too hot?

I am running a Gryphon Diablo 300 to drive a pair of Magico A3.  My room size is around 3m*4.5M.  I usually listen at around the 80db level, mainly to jazz and classical music.

My room temperature is almost always kept at 26 degrees Celsius in the summer.  After operating after an hour or so, the heat sinks of the 300 often gets up to 50 degrees with the top cover at 38 degrees.  My dealer told me these temperatures are normal but I feel this is hot (too hot?).

I should also add that the amp is placed on the top of a flat open shelf so there is no question on ventilation.

Any experience by other Diablo 300 users to share?

TIA!

50* (122*F) isn't that hot for electronics.  It might seem hot to us, but from everything I've seen, that's pretty normal.  

Think of the Class-A offerings from something like Krell.  Those units can get to 180*+ and still keep chugging along just fine.

26 C/79 F is a bit toasty during the summer, but for a class A/B design, you should be fine per your dealer. That ambient temp with pure class A would be a different story, however. If it worries you, though, knock down your AC a few degrees, and you'll notice a much cooler chassis temp.

AC Infinity You could try a version of this, I use one with each of my tube amps. They are very quiet and work very well to draw hot air away from the amp. AC Infinity makes many different kinds of fans to help keep electronics cool, perform their best and last longer. Just a thought....
