This PWM splitter from Phobya can supply up to 8 PWM fan with energy and also transfer the PWM signal of the first fan to all 8 fans. This makes sense for larger radiators.
The splitter is very compact and easy to bring in the housing below. By the back board , the tape may be attached to any position in the casing, as well as the use of two screws on the outside by holes.
|Side 1:||4Pin Molex, 4Pin PWM|
|Side 2:||4Pin PWM 8x|
