The product: Gigabyte has equipped the board with a heatpipe solution, covering the north and south bridges as well as the power regulators for the CPU. This is a classic solution, moving the heat from the components to multiple cobber profiles. To control all 4 cores in a Phenom CPU, good power regulation is crucial, but so are decent profiles who can handle the heat.
AMD uses 45nm technology for the making of the chipset, and there’s an explanation behind this. Active cooling is almost a requirement on the newer chipsets from Intel and Nvidia, but not on this one. The passive and relatively light weight profile on the Northbridge is enough to keep the chipset somewhat cool. The profile doesn’t get very hot, as we know it from Nvidia’s solutions as well.
