Is this too hot for my preamp? What should I do?


Hey guys,
I have a pair of Jeff Rowland monoblocks, and these puppies run warm. The amps are stacked one on top of the other, and on top of that is my Mark Levinson pre.
The pre is rather warm to the touch, the amps are radiating heat.
Should I change this? Or I am being dumb, and the pre wants the heat, as a warm unit sounds better?
Thanks

I had several repairs related to "heat x time". I then bought two Noctua NF-A14 PWM fans in a data shop, connected them to a 4.5 volt transformer, and placed them behind my hottest components. I don't hear them even from in front of the rack. I turn them on when I notice things are getting hot in the rack. The top plate of my preamp cooled down 12 - 16 degrees Celsius. Total cost, ca $90.
