I've printed out the Half Circular Part Blower by Torben (https://www.thingiverse.com/thing:2625974) and hooked up a single fan to it. Clipped off and isolated the leads for the second fan.
My only issue is now during a print the fan won't come on unless I turn it past 75% speed (on override). Even when the printer is idle and I adjust fan speed, the lowest I can go to turn it on is 20%, and even then can;t feel much air. I guess because of the single fan ducting I need a higher speed than when using two fans?
I thought the duct would allow me to be more efficient with a lower speed but I guess I need it set around 50% during layers in order to effectively cool.
