Ragav e requested "can i use a 3wire laptop fan with a esc?" So i found a 3 twine pc fan in my junk container and attempted it, i do not know what the third wire is for but i found it worked as a ordinary dc motor by connecting a battery direct to it and i could not get it to paintings the usage of a brushless esc so the answer isn't any. Update 1 craig nehring has helped with this explanation (thank you craig) 2 wire enthusiasts are just 12 volt, properly maximum all computer lovers are 12 volt but how they are managed varies. Three twine fans and four twine fans all have a crimson/black for /- input respectively. For the three twine fan the 3rd cord is a tachometer output. The voltage to the fan can be controlled if enabled inside the pc bios. Those 3 cord fans commonly, at start up, bang on at 12 volts to get them going and the fan controller then ramps the speed down for quiet operation. So... Fan pace is controlled via lowering voltage from a max of 12v. Four twine fanatics, equal as three cord but then what does the 4th wire do? This cord is for virtual speed manipulate, maximum 4 wire fans can be managed with the three wire method if the bios has a putting for that. The 4th twine can also (in maximum cases) may be used by varying the voltage among the black terminal and the 4th cord between zero to ten volts dc, or as a digital pulse mode modulation. To be able to summarise, 12 volt in to black and pink, 3rd twine tach sign output, 4th wire pulse modulated or analogue 0 to 10 volt velocity manipulate.
