Three-Fan Kit for External Cooling

This kit joins three 120mm fans into a single 360mm unit that runs from a 100-240V wall outlet. It targets builders who need airflow through a window, cabinet, server rack, workstation or greenhouse without wiring into a PC power supply.

Speed Range 500 to 2500 RPM

Each fan spins between 500 and 2500 RPM, and the inline dial controller adjusts voltage across the whole array. Dual ball bearings support continuous 24/7 operation for years, while the supplied grilles and rubber-mounted bolts protect fingers and dampen vibration.

Replaces Internal Fan Headers

The AC-powered controller removes the need for a motherboard header or a molex adapter, so the kit fits enclosures that lack 12V fan outputs. It is not suited for builders who require PWM signalling or software fan curves tied to CPU temperature.

Questions about this item

Will the three 120mm fans running at 500rpm to 2500rpm fit alongside older 12V components in my chassis?

The fans operate on 12V DC supplied by the included controller, matching standard 12V component voltage, and the 360mm combined length fits typical 120mm mounting points.

How can I confirm the dual ball bearing fans are spinning correctly after plugging the controller into a 100-240V outlet?

Turn the dial controller; fan speed should rise smoothly from low rpm to maximum with no grinding noise, and airflow should be felt through the protective grilles.

Does the box include the rubber feet and mounting bolts, or must I buy them separately?

The set includes protective grilles for both sides, rubber feet, and the bolts that thread into those feet; no extra mounting hardware is required.
