a
Minimum: 0% load on all components; minimum power consumption started and idle.
Typical: 25–50% load on all components; good indication of most application loads.
Maximum: 100% load on all components; generally cannot be reached in normal applications.
b
Chipset heaters operate at low temperatures to keep the CPU and PCH within specified operating limits.
