In Figure 6.28, you can easily see the heatsink base attached to the CPU with four liquid-filled
pipes attached to it, which in turn are connected to a pseudo radiator.The radiator sits between the
back of the case and the large case fan. When the case fan spins, it pushes air through the radiator,
which cools the CPU. Conceptually, this is similar to a car radiator and fan.The end result is that the
fan cools effectively at a fairly low speed (about 2,000 RPM) and is very quiet.The fan is variable-
speed, though, and can speed up as needed if the temperature goes up.The threshold is settable in the
BIOS.The fan is capable of reaching speeds of up ...
