these instructions are for the adda and ebmpaspst 48V high power fans that need full speed for cooling the high power output transmitters. This fix is for these fans only. It may not work on yours for random pc fans or laptop fans.
this is how you prepare and connect 4 wire fan to run with full speed. Red wire is positive (+), black wire is negative(-) voltage.
yellow and blue wire are for tacho and pwm control wires that you don’t need if you want it to run with full power.
