用于安装孔大于3mm的风扇

比如8cm 9cm 12cm 14cm 部分6cm也可以用

请注意风扇必须要风扇孔间隔，不能用于类似于B19那种孔连在一起的风扇
For fans with mounting holes greater than 3 mm

Such as 8cm 9cm 12cm 14cm part 6cm can also be used

Please note that the fan must be spaced from the fan hole and can not be used for fans of the same type as holes in B19
