PWM fan hub for desktop builds
This ThreeBulls splitter connects one motherboard header to five case or CPU fans using a single 4-pin PWM source. The 15.7 inch sleeved cable keeps routing tidy inside standard ATX and micro-ATX chassis. It suits builders adding multiple intake or exhaust fans without extra headers.
Practical limits of the 4-pin PWM interface
The hub passes one PWM control signal to all five outputs so every connected fan runs at the same duty cycle. Three-pin fans receive constant 12 V power and cannot be speed-controlled through this adapter. Total current draw must stay within the motherboard header rating.
Single 4-pin male header supplies all five fans
The splitter draws power from one 4-pin male plug on the board, distributing it across five female connectors. If the combined fan current exceeds the header limit, the system may throttle or shut down. Builders needing independent speed curves or higher aggregate current should use a powered hub instead.

Questions about this item
How many fans can I connect with the 1-to-5 splitter?
The hub splits a single 4-pin header into five connectors, so you can run up to five PWM or voltage-controlled fans from one motherboard socket.
Will the 15.7-inch length reach from my motherboard fan header to the top or rear case mounts?
At 15.7 inches the sleeved cable spans most mid-tower layouts, giving enough slack to route behind the motherboard tray to top, rear or front fan positions.
Does the 4-pin PWM header on the splitter pass speed control to 3-pin fans as well?
The splitter carries the PWM signal to all five ports; 4-pin fans receive full PWM control while 3-pin fans run at variable voltage governed by the same header.
