SummerTime and Amp Heat


My B&K has some massive heat sinks but I still place a fan on it to draw cooling air through it. It seems each summer I need to do this. Am sure some of you do as such?

It depends on the design too. I run a fan on some amps that run hot, and can shorten the caps lives. I don't like hot transformers either, power or output. If it runs real warm, I use a muffin fan, summer or winter.

Fans? We don't need no stinkin fans! (loosely quoted from Blazing Saddles).

I live in the desert southwest, A/C works for me. My Pass monoblocks run pretty hot but Nelsons designs account for this and seem to last for a long time. I don't need or like to leave stuff on 24/7. I'd say, just be smart.

I grew up with central air and heat. The dealer that helped put my parents system in a half century ago, put muffin fans on the amp.

Cannot assume that power supply are automatically hot if the heatsink is hot.....

There are plenty of resistors close enough to the coupling, and other caps inside the amp to soak up the heat from those resistors. A lot of the time when I buy something, I look inside and see the caps or resistors leaning toward each other on one side of the amp (one channel), and not the other channel. This is quite common, and on upper end gear, not just mid-fi. I've seen this in all kinds of electronics, more so with PC boards. A lot of heat inside some of them. That's why I said it depends on the design. I have some stuff with a lot of clearance that needs nothing in the way of extra cooling. When some people buy this type of gear, they'll say it's just a big box of nothing. Maybe the designers did this for heat and other beneficial reasons.
I forgot about that song (Don't Worry). I need to listen to it, but will still worry about something anyway.LOL.
