Thermal/Cooling Requirements
The Express-IBR is designed to operate at its maximum CPU speeds of 1.7GHz, 1.8GHz, 2.1GHz, 2.3GHz,
or 2.5GHz and requires a thermal solution to cool the CPU, PCH, and voltage regulators. ADLINK offers
two optional cooling solutions as well as a heat spreader platform on which to build a cooling solution. (See
Table 2-7 for descriptions of cooling options.)

NOTE The overall system design must keep the ICs within their operating temperature
specifications.
