Fan on Amp Unbeatable

So, I have an older amp from the 70s. It's a solid state amp and the fan is so loud it's distracting. It's my first largest solid-state amp. I've been using tube amps for the last 15 plus years. I can't imagine fans are supposed to be overwhelming Lee loud. Has anybody else ran into this kind of issue and if so, how did you fix it?

Hmm will try some type of nose muffler first. Need to be careful of not allowing airflow. Any other solution involving opening the case will have to be done by my tech. $$$$. :<(

I’ve got a 5" side discharge on my tube pre-amp and it keeps it very cool. It has three speeds. On low you can hear it when you are next to it, but not across the room.

My SS amp has enormous heat sinks but I might put one of these on top of each one anyway.

The company makes thermostats for their fans as well.

“I have had several amps like the Krell KMA 100 that had fans you couldn’t hear”.

I still miss my KMA100s after all these years, my first true high end purchase back in the 80s

spinaker yes they were very special back then. Unfortunately those output transistors ran hot and many of them eventually blew their output stages. Like a light bulb turn them on and off a lot and eventually.....
