We have a new review for the Noctua NA-FH1, an 8-way fan splitter that allows users to link up to 8 12V or 5V fans to a motherboard header. It also connects to the NA-FC1 fan controller (sold separately) for additional and individual fan speed control options. The NA-FH1 provides up to 24W of total power through the 4-pin PWM input, or a maximum of 54W via SATA (12V fans only).
