Thermal/Cooling Requirements

The CPU, Memory Hub (Northbridge), I/O Hub (Southbridge), and voltage regulators are the sources of heat on the board. The MightyBoard 821 is designed to operate at its maximum CPU speed of 2.0GHz or 1.5GHz. Both CPU versions (Celeron M or Pentium M) and the Memory Hub (Northbridge) require a heatsink with a fan.
