Extension cable for connecting 3-pin fans (CPU cooler, case fan, etc.) to the motherboard connector (3-pin). Using the cable, the speed of a fan can still be read (3-pin Molex plug on both sides). The length of the cable is about 60 cm. Since the female connector is closed, NO 4-pin PWM fan can be connected. On the input side - for example, the motherboard - this is not a problem.
