③ Heat Transfer via Heatpipes
Virtually ever-lasting heatpipes transfer heat away
from the CPU, VGA chipset, and Northbridge 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 six heatpipes can transfer up to 150W of heat
from the CPU - sufficient for the hottest CPUs on the
market. 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. The three heatpipes can transfer up to 75W
of heat from the VGA chipset - sufficient for the hottest
VGA cards on the market.
- Northbridge Heatpipe
Heat from the Northbridge chipset is transferred to the
heatsink plate through a single heatpipe, 5 millimeters
in diameter. This heatpipe can transfer up to 20W of
heat.
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 and the Northbridge chipset
by 5 to 10° C.
