Attention
We strongly recommend you that attach a cooling fan on top of the
CPU and also attach the fan power cord onto the mainboard CPUFAN
header, to avoid your CPU damaged due to high temperatures.
In general, the fan power cord is designed and should be attached with
a specific direction. The black wire of the fan power cord is Ground and
should be attached onto the header pin-1.
