So I've built a variable fan control using LM317, 10k rotary pot a 510ohm resistor a 1uf cap and .22uf cap (I had no .1's) following this video
The fan is rated for 12v @ 0.18amps which is 2.16watts, I've got my bench power supply set to 12v and 0.3amps but the fan is only drawing 0.08amps on the PSU which obviously means it's nowhere max RPM, I've tried running just the fan connected to the PSU and again it only draws that same amount of amps, only when I turn the voltage up on the PSU do the RPM & current draw start increasing to what it should be
I'm obviously doing something wrong but I don't know what ?
