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
: E5 m) T0 j( N但是只有CPU控制模式一个选项, 也许同时影响两个风扇?3 o1 z9 d5 n) `& {: J$ b

Specifies how to control CPU fan speed. This item is configurable only if CPU Smart FAN Control is set to Enabled.
+ o$ V$ P1 e* E# e$ |* ~Auto Lets the BIOS automatically detect the type of CPU fan installed and sets the optimal CPU fan control mode. (Default)

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.( u# D3 b0 n# L8 P, ^
因为电压控制模式能兼容3/4pin风扇, 默认为电压控制模式并没有什么错3 r! s+ V; @( s* V! I

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?% N, [/ C# E$ N( u* g0 P* c
