COMe-cHL6 / BIOS Operation

Passive Cooling

The ACPI OS assesses the optimum CPU performance change necessary to lower the temperature using the following

equation

ΔP[%] = TC1(Tn-Tn-1) + TC2(Tn-Tt)

ΔP is the performance delta, Tt is the target temperature = passive cooling trip point. The two coefficients TC1 and TC2

and the sampling period TSP are hardware dependent constants the end user must supply. It’s up to the end user to set

the cooling preference of the system by setting the appropriate trip points in the BIOS setup.

See chapter 12 of the ACPI specification (www.acpi.info) for more details
