Not much to say, they're three pin splitters, they're black, and they work. I appreciated that the College Guys website was the only one I found explaining the reason for only two pins in one of the plugs -- the third pin is for fan RPM feedback and motherboards can only take one signal. I would pair to identical fans so your feedback is accurate for both.
If your fan is pulse width modulation (PWM) controlled you need the four pin splitters.
