Gigabyte P55A-UD6 Motherboard

Other Features (Cont'd)

One amazing detail in P55A-UD6 is its cooling system. As we said before, this system has heatsinks over the chipset, the voltage regulator transistors and the last one seems to cool something where usually the chipset southbridge is located, all of them connected with heatpipes.

We removed this system to take a look and understand how it works. In Figure 11, you can see the heatsink set and in Figure 12 the motherboard without it.

In Figure 13 we see the chips cooled by the last heatsink: ITE IT8213, which controls the ATA-133 port, and Marvell 9128, which controls the SATA-600 ports.
