Overclocking does not work, the farm ignores any changes in the overclocking

#1

Hello, I do not understand what’s happening to my farm. In the left column, GPU 0 shows the wrong temp, and in the same column all the other video cards are shown with 0% cooling fans. Because of this, the overclocking does not work. no matter how much I put it, the farm ignores any changes in the overclocking. Someone know what to do? Thanks
