Fan on Amp Unbeatable

I set one of these on top of my AR LS-16 tube pre-amp and it really keeps things cool even on the lowest fan speed:

So, I bought two of them to set on top of my solid state Proceed HPA2 amp. It has two huge heat sink openings that draw from underneath.

With the two fans on low the aluminum heat sink hardly even feels warm.

So the question is this: is there any chance of a SS or tube component running too cool?

What a clever little fan @n80! I'm gettin' me some.

I chose that particular model because my components are in an open front console without enough clearance for an upward venting fan.

You can also get a thermostat module very inexpensively if you feel like you need it. Mine do great on the lowest setting so I don't see much of a need.

I probably don't need them at all but my listening room is a converted sun porch and the HVAC is not as effective in here and it runs 4-5 degrees warmer than the rest of the house in summer. 

stringreen..... ma man!

To fan or not to fan....I keep my SAE 502 on wood blocks which keep the preamp off of it by like 2 inches....no problem.
