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!

My PS Audio BHK 300 mono blocks are warm to the touch when they’re just idling and can get down right hot if I run them above 90 dbs.

Efficiency is inverse to heat in a device. If waste heat is a problem switch to nice class d. 

@mylogic Imho if you can fry eggs on your amp you're into or just about needing to replace it....unless you're into runny.
Over medium myself...I bring the bacon...

Frying eggs

I was just trying to add a little ironic humour to some of the posts. They reminded me of the lyrics to a song…”The heat is on”

The nearest l have been to a Krell was when watching “The Forbidden Planet”

l thought it quite funny people talking about how hot the surface of their amps ran up to. If they are that hot outside, what the ‘hell’ (literally) are the circuits heating up to inside?

l can only say as an observer, the Krell amps may look ‘cool’ from the outside, but……..The big but is, heat may be good for a car engine but essentially and ultimately the biggest potential killer for delicate electronics. The same is true for any piece of electronics.

Reference the film, the advanced civilisation….the ‘Krell’ effectively blew their own brains out. Same scenario?
