Before I modified my internal fan to run continuously I never heard it run. I always figured too many people complained about the noise so they shut them down. The internal fan is more than capable of keeping the unit cool, so I can't say there is a design flaw, especially on a 10 year old design.
I have 1 that has been trouble free for over 7 years, the second I had to replace the capacitors.
