What about a fan blowing over McIntosh 7205 AMP?

Seems like my Amp was getting pretty warm so I put a small fan to blow over the top of it which seemed to cool it down. Talked to a Mgr at a stereo store and he said not a good idea. Seems to me they put fans in computers to keep them cool, but he was pretty sure I could do more harm than good. What is anyone else's opinion???? just thought I would see if anyone wanted to put in some feedback..

I don't see how it could harm it,but,it's better to set your fan up to pull heat from the unit.Just my opinion.

Warm is normal, why the need for a fan, is the amp going into thermal shutdown? Typically, fans are used to exhaust the heat from the enclosure thus creating a more natural cooling convection. I know that designers of tube equipment frown on fans blowing directly on the tubes as it could excite the tube thus causing microphonics and noise. I am not aware of any amp in which the fan blows onto the electronic, most exhaust the heat.

That could be a really good idea. Use the fan as an exhaust. pushing air away instead of right on it...thank you
