2.7 Environmental and Power Specifications
2.7.1 Operating Temperature and Temperature Control
The maximum and minimum operating temperatures for the WAFER-LX3 are listed below.
WAFER-LX3-800 (board revision 1) : Operates in a normal range of ambient
temperatures between 0°C ~ +60°C
WAFER-LX3-800W (board revision 1) : Operates in a wide range of
ambient temperatures between -20°C ~ +80°C
WAFER-LX3-800 (board revision 2) : Operates in a normal range of ambient
temperatures between 0°C ~ +60°C
A cooling fan and heat sink must be installed on the CPU. Thermal paste must be
smeared on the lower side of the heat sink before it is mounted on the CPU. Heat sinks
are also mounted on the Northbridge and Southbridge chipsets to ensure the operating
temperature of these chips remain low.
