Barry,

I have the DDEC IV manual in pdf format. Section 5-15 is all about fan control. Covers lots of different options and different fan manufacturers. I have not had fan trouble or heating problems yet, so I have not studied my system in any detail. My only real observation was made when I accidentally turned the volume up on my rear camera and could hear the fan. I did not know what it was at first, but later figured it out. Just from listening I would say it is not PWM, but rather something closr to ON/Off or High/Low.

If you will PM me with your email address I will send you a copy of the entire manual.
Russ
