Hello, I’m just curious how are other Taz 5/6 owners powering their aftermarket 12v 40mm part cooling fan in place of the original 24v.
As multiple posts suggests, most non-original 24v fans have issue with RAMBo’s PWM at low RPM, some have suggested using 12v fan instead as there are many more choices. I came across this post regarding dropping the RAMBo’s 24v output to 12v using Zener diodes so I ordered a few 12v and 6v diodes to experiment.
The good news is that 12v fans work exactly as expected, but what I am concerned about is the incredible amount of heat the one 12v diode was generating, by simply touching hot end thermistor to the diode it was reading over 70C! Not sure how I would have to keep this thing from melting nearby wires.
Curious how are fellow Taz owners getting 12vs to run properly with Taz’s PWM and not use an external power source, or if anyone has any suggestions on well priced 24v fans that are easily accessible.
