As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
Good for STEM education / Arduino projects. Runs at reduced speed from 5V and still slower with a PWM signal through a transistor. Yellow wire is hall effect sensor, use a pullup resistor and view the square wave on a scope appears to be 2 pulses per revolution. Use a reflective IR sensor TCRT5000 and sense a little piece of foil taped to one blade to measure RPM. Have students carefully place a little piece of paper in the path of the blades like a playing card in bicycle spokes and guess the clicks per second frequency and by extension the RPM. Finally build closed loop control system to command a specific fixed RPM under different loads.

Great price, Im getting a bunch of them!
...the yellow wire is a tachometer output. It is used in smart systems to detect a fan failure to prevent overheating damage by either notifying a user or shutting off high-powered loads.
Works Good - No Wiring Diagram
This is a 3 wire fan -- by trial and error, found out that red + and black - are the 12VDC power in. Does not accept reverse polarity. Have no idea what the yellow wire is -- probably a sense line of some sort, but seems to work fine without connection
