" S0 ~3 L* ~ c我记得我看过技嘉Q57主板的说明书是可以设置风扇如何调速的, 电压控制或是PWM控制
' r" y1 Q1 F5 A9 i& f但是只有CPU控制模式一个选项, 也许同时影响两个风扇?

Note: The Voltage mode can be set for a 3-pin CPU fan or a 4-pin CPU fan. However, for a 4-pin CPU fan that is not designed following Intel PWM fan specifications, selecting PWM mode may not effectively reduce the fan speed.

那个客服根本在不懂瞎扯, 第4脚如果是温度回传那是不指望跟4线PWM风扇兼容了, 谁能用?
