EAKHELB’s 240mm dual-fan assembly solves a specific cooling problem. It’s for the PC case, server cabinet, or small workstation box that needs serious, dedicated airflow without tapping into your system’s motherboard or PSU. The included AC-to-DC power supply and wired speed controller make it a self-contained cooling module.

You control the speed from a whisper-quiet 3V up to a full 12V, where each fan moves 107 cubic feet of air per minute. The dual ball bearings are the key spec here. They’re rated for 5,000 hours of life, which translates to reliable, 24/7 operation for a server or a constantly-running rendering workstation. At full tilt, the sound is a focused 38 dBA—it’s audible, but it’s the sound of work getting done.

Installation is straightforward: mount the fans, plug the controller into the wall, and adjust. The honesty is in the cabling. You’re managing a power brick and the controller wires, so this isn’t for a minimalist showcase build. It’s a functional, powerful tool for keeping your critical hardware cool under sustained load.
