Attention
You can avoid damaging your CPU due to high temperatures with
proper cooling equipment. It is recommended that attach a cooling fan
on top of your CPU. Use the JSFAN1 header to attach the fan cord.
On most fan power cord, the black wire of the fan cable is the “ground”
and should be attached to pin-1 of the header.
