Intel D 820
2. Specifications
In Device Manager, you'll notice that the D 820 is identified as two processors, while with CPU-Z you can read the details for each one separately.

The FSB runs at 200MHz while the Bus speed at 800MHz. The multiplier is set by default to 14.
The temperature levels for the D 820 are not too far from those of a P4. In idle, the temperature is close to 41°C while under full load, it reaches 57°C. This is much lower than it was in the case of the D 840 which started at 54°C and under full load, we saw go over 70 °C.

If you decide to go for a more efficient cooling system, such as the Arctic-Cooling Freezer 7 PRO or the Thermaltake BlueOrb II, the temperature levels will be greatly reduced.
