UMLIFE 4-Pin PWM 1-to-5 Fan Splitter

This UMLIFE splitter hub expands a single 4-pin PWM motherboard header into five fan connections. The 2-pack supplies two hubs for cases that need more fan headers than the board provides. Each hub accepts both 4-pin PWM and 3-pin fans, though 3-pin units will run at full speed because they lack PWM control. The black PVC-insulated cables use 1007 24AWG tin-plated copper wire for reliable conductivity.

Check header type and fan count before ordering

Verify that your motherboard offers a 4-pin PWM header to drive the hub; a 3-pin header will not provide PWM signalling. Count the fans you intend to connect — each hub supports up to five, so two hubs handle ten fans total. Ensure the 35 cm cable length reaches from the header to every fan mounting point in your chassis. The hub draws power through the motherboard header, so confirm the header’s current rating can supply all attached fans.

Behaviour under sustained load

The tin-plated copper conductors and PVC insulation maintain stable power delivery during continuous operation. PWM signalling from the motherboard regulates every connected 4-pin fan simultaneously, keeping speeds consistent over long sessions. Because 3-pin fans receive constant 12 V, they run at maximum RPM for the duration of the load. The flame-retardant insulation resists heat build-up inside a closed case during extended use.

Questions about this item

Does the 2-pack include all cables needed to connect five 4-pin PWM fans to one motherboard header, or must I buy extra leads?

Each of the two hubs has a single 4-pin male plug that goes to the board and five 4-pin female sockets for the fans, so the pack connects up to ten fans with no extra cables.

I see the hubs also accept 3-pin fans; should I choose the 4-pin or 3-pin version for a build that mixes both connector types?

There is only one version — a 4-pin PWM hub that accepts both 4-pin and 3-pin plugs. 3-pin fans will run at full speed because they lack the PWM control wire.

The cable is listed as 35 cm; will that reach from a bottom-mounted motherboard fan header to fans at the top of a mid-tower case?

At 35 cm (13.7 inches) the lead covers typical mid-tower distances; measure your specific routing path to be sure.
