"The northbridge on this motherboard is Intel's P965,
which is cooled by a passive aluminum heatsink. Unlike Gigabyte,
ASUS, and the other enthusiast brands that build all sorts of
cooling contraptions with heatpipes that run from the southbridge
to northbridge to the VRM, ASRock just uses passive aluminum
heatsinks. Granted, this cooling is suffice if not overclocking and
does save on manufacturing costs."
