Fanless Design - Heat-pipe
The Heat Pipe design effectively directs the heat generated by the chipsets to
the heatsink near the back IO ports, where it can be carried away by existing
airow from CPU fan or bundled optional fan. The purpose of the innovative
heat pipe design on this motherboard is that the groundbreaking fanless
design does not have lifetime problems as a chipset fan does. Furthermore, it
provides options for users to install side-ow fan or passive cooler. The Heat
Pipe design is the most reliable fanless thermal solution to date.
DO NOT uninstall the heat-pipe by yourself. Doing so may bend the tubing and
affect the heat dissipation performance.
Optional Fan (for Water-Cooling or Passive-Cooling only)
The optional fan is specically designed to provide sufcient airow over the
CPU power modules and chipset area when water-cooling or passive-cooling
is utilized, ensuring effective heat dissipation for the entire system. See page
2-36 for details.
