OOOPPS!! You appear confused. You say you want to control the speed of the motors in PWM fans, which are ALWAYS 4-pin, and then you ask about 3-pin fans. The Deepcool FH-10 fan HUB is for 4-pin PWM fans, and you cannot control 3-pin older fan speeds with it.
Now, MAYBE your problem comes from the use of "3-pin". It means two VERY DIFFERENT things on lighted fans. 3-pin fan (Voltage-Controlled) MOTORS and 4-pin PWM fan MOTORS are different and require their own correct mobo header connections (and fan Hub systems). 3-pin (ADDR RGB 5VDC) LIGHTS in fan FRAMES are very different from 4-pin (plain RGB, 12 VDC) LIGHTS. You cannot mix the two lighting systems together on a single circuit, so you must match the LIGHTING type of your fans to...
