The BIOS 0035 version has bug. It always sets the fan Minimum Duty cycle and the Minimum Temperature back to the value 30 / 52 and does not store the entered custom settings.
After applying custom setting press F10 followed by 'Y' to save those settings and exit.
Of course but F10 does not work in 0035. No problem in previous version 0031.
