All heat generating components are thermally conducted to the heatspreader in order to avoid hot spots. Thermal Design of COM Express 1. Installing the COM Express Firmly insert the COM Express into the COM Express socket. 2. Installing the heatspreader A heatspreader must be installed on the COM Express. Thermal pads must be smeared on the lower side of the heatspreader before it is mounted on the COM Express. Heatspreaders are mounted on the CPU, Northbridge and Southbridge chipsets to ensure the operating temperature of these chips remain low.
