...way under the expected value. By randomly changing values in the unknown tables of the vbios, I found out that there is a fan calibration table at the offset 0x18 in the BIT P table (version 2). In this table, I identified 2 major 16 bits parameters at offset 0xa and 0xc[2]. The first one, I named pwm_max, while naming the latter pwm_offset. As expected, these parameters look like a mapping function of the form aX + b. However, after gathering more samples, I found out that the output was not continuous when linearly increasing pwm_offset [1]. Even more funnily, the period of this square function is...

...@ Your fan can be driven in different modes: NOTE: Be sure to use the manual mode if you want to drive the fan speed manually -NOTE2: Not all fan management modes may be supported on all chipsets. We are -working on it. +NOTE2: When operating in manual mode outside the vbios-defined +[PWM_min, PWM_max] range, the reported fan speed (RPM) may not be accurate +depending on your hardware.
