③ Heat Transfer via Heatpipes
Virtually ever-lasting heatpipes transfer heat away
from the CPU and VGA chipset, preventing system
crashes due to overheating.
- CPU Heatpipes
Heat from the CPU is transferred to the heatsink plate
through 6 heatpipes each 6 millimeters in diameter.
The CPU Block Base is made of pure copper to ensure
the highest cooling performance.
- VGA Card Heatpipes
Heat from the VGA Card is transferred to the heatsink
plate through 3 heatpipes each 6 millimeters in
diameter.
④ Heat Transfer via Rear-mount Thermal Blocks
When the Rear-mount Thermal Blocks are installed on
the back-side of the motherboard in line with the
position of the FETs (Field Effect Transistor) and the
Northbridge chipset, each can lower the FET
temperature by 10 to 30°C (50 to 86°F) and the
Northbridge chipset by 5 to 10°C (41 to 50°F).
