What do you guys think of the adjustability of the circuit though?
Do you feel it makes it a bit complicated to need to adjust the setting of the circuit to suit your fans or do you think a one size fits all method would be better, but lose the fine tuning of the way the fans react to PWM cycle?
Just in case you aren't aware of what I'm asking. You may have noticed I added a potentiometer to the design so you can dial the power output of the circuit to match your needs. You can adjust so that the fans don't speed up too much, even at 100% duty cycle, or dial them up so they don't slow down too much, even at low duty cycle. It's a slight fiddle but I think it's a nice idea to dial in the cooling you want, but still have some control over what goes on.
Thinking about it though it's also easy to make fixed devices with different outputs, 510, 1k, 5k etc but you'd lose the fine tuning.
