Odroid UX4

My Raspberry Pi died so I replaced it with the 8 core Odroid UX4.

ODROID-XU4 is a new generation of computing device with more powerful, more energy-efficient hardware and a smaller form factor.
Offering open source support, the board can run various flavors of Linux, including the latest Ubuntu 15.04 and Android 4.4 KitKat and 5.0 Lollipop.
By implementing the eMMC 5.0, USB 3.0 and Gigabit Ethernet interfaces, the ODROID-XU4 boasts amazing data transfer speeds, a feature that is increasingly required to support advanced processing power on ARM devices.

Set the fan

I was worried about the noise. It is not loud but audible. After:

change the governor to "interactive" from "performance"

It is not running apart from startup See Also
