PC Water Cooling System with Wireless Control

Overview

This advanced remotely controlled PC water cooler design integrates a high-efficiency power unit within the PC and features a user-friendly HMI control panel on the desk. Utilizing Bluetooth® Low Energy (LE) for seamless connectivity, this setup offers convenient wireless control over the cooling system. The water cooler effectively dissipates heat from processors and critical components like graphics cards, ensuring optimal performance and reliability in high-performance computing environments.

System Benefits​:

  • Wireless HMI provides flexibility and user convenience.
  • Bluetooth LE enables smartphone control of the power unit, enhancing ease of use.
  • The MCU manages simultaneous control of multiple pumps and fans, allowing flexibility in cooling configurations.
