Obviously the answer is size and money, but I hate fan noise. I know that fan noise is quiet in comparison with the output of a gigging amp, and that at a gig no one notices but when playing in the house it is sooo annoying, even on an amp with a quiet fan.
Just as an example, the new Markbass Big Bang. It's tiny, even smaller than a LM3 and I bet the fan is whirring like a bastard.
the guts of an LM3 in a normal 19 inch rack with a properly designed heat sink / fins etc would negate the need for a fan. Wouldn't weigh much more either.
I love my RH750. It's ace, and of course it's not designed to be used at whisper levels at midnight but I do long for the end of fans!!!

Should be pretty simple to disconnet the fan. Find out if the amp cutting out due to overheating is any less annoying
