S6800-54QT 风扇如何调速

各位好，请问S6800如何进行风扇调速？风扇太吵了。

我看过这个帖子 https://zhiliao.h3c.com/questions/dispcont/233386

但是没有答案，并且命令也不对。下面是我这边机器的环境信息：

我看了一下在probe模式下有如下的指令：

上面我没找到直接配置风扇百分比的，能看到，但是没有配置。

另外仅仅只有tadj参数可以配置，但是不知道这个参数是什么，看说明是配置风扇气流方向，然后后面的值和字符就不知道是什么了。

请教一下是否可以配置fan的速度，百分比？或者通过升级到某个版本，降级到某个版本允许进行风扇转速配置？
