 Please confirm that the fan cable complies with the socket cable. Power cable
(usually red) is in the middle position. In addition, please confirm the earth
cable (usually black) and fan speed output impulse signal cable (other colors).
Some fans have no speed detection while the output of the cable is up to 12V.
These substandard connections will destroy the CPU card. It is recommended to
use a fan with speed detection.
 Adjust the fan’s airflow to the direction of heat venting.
