I am in the process of building the system software (gentoo installation, so lots of compiling). I am doing this mostly unattended, and I am finding the device shutdown. It seems the fan doesn't always kick in, and when it doesn't the temperature reaches a point where it auto shuts down. I have a V8 board, which came from the kickstarter. I have the green dot on the side of the fan. I have set the fan according to the instructions for this configuration - 100% speed above the lower temperature - in other words no pwm. Are there issues with some of the fans?
