8-Port PWM Fan Hub
The EN-Labs PWMHUB10SMG expands a single motherboard PWM header to eight fan connections. It draws 12 V power from two SATA 15-pin connectors on the power supply, allowing up to eight 12 V 2 A chassis fans to run simultaneously. Each output includes a capacitor for device protection, and a 1.64 ft PWM cable is supplied for the motherboard link.
Replaces Daisy-Chain Splitters
Basic Y-cables share one header's limited current and cannot drive multiple high-power fans reliably. This hub moves the load to the PSU, reducing motherboard power draw and heat while keeping PWM speed control for every 4-pin fan attached. The upgrade is worth it when you need more than two or three fans on one header or when fan current exceeds what the board can safely supply.
Suits Builders With Many Case Fans
Ideal for enthusiasts running several chassis coolers who want centralised PWM control from one header. Builders who need independent speed curves for each fan should look elsewhere, because only the red CPU-fan port passes an RPM signal back to the motherboard. Systems without a PWM fan on that red port will run the hub at full speed with no speed regulation.

Questions about this item
How many SATA 15-pin connectors from the power supply does this hub need?
The hub draws power through two SATA 15-pin connectors from the PSU.
Which fan header on the hub must be connected first for PWM control to work?
The red header is designated for the CPU fan; PWM control is disabled if this header is left unconnected.
What ongoing maintenance does the hub require after installation?
No scheduled maintenance is needed; only inspect cable ties and the self-stick mount if the system is moved.
