As mentioned previously, To use that amp in AM mode would require adjusting your radios output dead key power to 1 1/2 watts - so the amp won't be over-driven. If you don't know how to do that - don't bother - you can really screw it up if you don't know what you are doing. Adding a fan won't help that situation.

But mackmobile is right about adding a fan - simply because most amps need more cooling than the factory provides them when built. It's a smart move.

On SSB, I don't think the radio will over-drive that amp. So, if you stay on SSB and stay off AM with it - you should be OK. But a fan would still be the thing to do if you want to keep it working for a long time. Just get a 4 inch fan out an old computer that runs on 12-14v's and wire it into the power cord attaching it to the heat sink of the amp. A quiet fan is preferred. Same is true for your Palomar amp - two fans would be better for that one.
