Most certainly wrong (scaling is never needed for fan speed) unless
the IT8620E uses a different clock frequency than all other chips.
Rather unlikely if you ask me. So I think your fan has some form of
automatic speed control, either integrated or done by the chipset, and
it spins faster in the BIOS simply because the CPU is busier in the
BIOS. If I am correct then just put some load on the CPU under Linux
and you'll get the same fan speed as in the BIOS without the compute
statement above.
With CPU load near 50%:
It seems that the fan speed at +-100 RPM is the same that in BIOS at the
same temperature.
Without CPU load:

coretemp-isa-0000
Adapter: ISA adapter
CPU Temp: +24.0°C (high = +80.0°C, crit = +100.0°C)
Core 0: +24.0°C (high = +80.0°C, crit = +100.0°C)
Core 1: +22.0°C (high = +80.0°C, crit = +100.0°C)
it8728-isa-0a30
Adapter: ISA adapter
+3.3V: +3.32 V (min = +3.14 V, max = +3.46 V)
+12V: +12.09 V (min = +10.80 V, max = +13.23 V)
+5V: +5.10 V (min = +4.76 V, max = +5.25 V)
CPU VRIN: +1.72 V (min = +1.62 V, max = +1.78 V)
VDRAM: +1.50 V (min = +1.43 V, max = +1.57 V)
3VSB: +3.38 V (min = +3.14 V, max = +3.48 V)
Vbat: +2.90 V
CPU Fan: 1161 RPM (min = 10 RPM)
System Temp: +26.0°C (low = +10.0°C, high = +60.0°C) sensor = thermistor
Thank you again.
