I wasn't trying to be funny. I was just pointing out that the market recogized exacly what you are saying and offered internal fans for the Plus, 512k, and 128k. If there wasn't a need, why offer it?
The Radius FPD and 16 MHZ accelerator for the Plus included a fan. I put a fan in a Plus myself and found it to be too nosiy. There was an EXTERNAL fan that sat on top of a Plus and sucked air out (MacCool?).
I agree that Apple should have added a $2 fan to the Plus during it's lifetime.
