Hi,

I´m using latest BIOS and want to put the CPU fan and chassis fan (4 pins - PWM) to rotate in the same degree, but even when I choose in BIOS to both use the same sensor (CPU) and same behavior (NORMAL), the CPU fan changes accordingly with the load and temperature, which is fine, but the chassis fan stays in the same rotation all the time, ignoring it. I want to put both fans to change rotation in the same way, but its not happening. Any help?
