Remote Controlled PC Water Cooler

Renesas' reference design splits PC water cooling into two parts, the power unit inside the PC and the HMI control panel on a user’s desk

Image of Renesas' Remote Controlled PC Water CoolerRenesas’ winning combination reference design for a remote controlled PC (desktop/tower/mini-tower) water cooler lowers the temperature of the computer processor and other critical components of the system such as graphics cards. PC water coolers absorb the heat from the components inside the system, rather than blowing the hot air around the case, as is typical with air cooling systems.

Renesas' remote controlled PC water cooler solution splits PC water cooling into two parts, the power unit inside the PC and the human-machine interface (HMI) control panel on a user’s desk, connected via Bluetooth® Low Energy (LE) to the power unit.
