The split cable includes both 3-pin and 4-pin options. When you connect both fans, the CPU fan header will use PWM regardless of which connector you choose.

Both units will use PWM control. One connector has four pins while the other has three, but the three-pin lacks the RPM wire so fans won’t report speed via the same header.
