On cooling-related websites, lower temperatures typically correspond to better products. On this particular page, the opposite is true: The higher temperatures a CPU can withstand, the less cooling is required. CPUs with low electrical power, but high temperature rating can be used with more quiet and more compact coolers. An example for such a CPU is the Pentium-M, which dissipates less than 25 watts, but may reach temperatures of up to 100°C. The worst-case example is the Pentium 4 Extreme Edition 3.46GHz, which dissipates over 110 watts, but may only reach a maximum temperature of 66°C. Obviously, you need a large and possibly loud cooler here.
