3.5 Slot large three-fan radiator, new patented milling groove vapor chamber
▲ Extreme Cooling System three-fan radiator
ASUS ROG Strix GeForce RTX 4080 OC Edition graphics card is equipped with the same 3.5 Slot large three-fan radiator as ROG Strix GeForce RTX 4090, with a new patented milling groove vapor chamber connecting four 8mm pure copper heat pipes and three 6mm pure copper heat pipes It runs through the entire large-area heat dissipation fin radiator, and is equipped with nickel-plated surface treatment. The vapor chamber operates in a cycle of evaporation and condensation of the operating fluid closed in the plate-shaped cavity, and has rapid heat uniformity, rapid heat conduction and heat diffusion. It can transfer the waste heat of the core chip to the whole heat sink in a more balanced and rapid manner. This time, the volume of the new giant radiator has been increased, and the thickness of the radiator has been increased from 2.9 Slot to 3.5 Slot. The thickness of the radiator is thickened, and the general M-ATX, M-ITX and other small chassis are likely to have problems with insufficient compatible space or insufficient air suction space.
The vapor chamber radiator used by ASUS ROG Strix RTX 4090 this time has a new patented milling groove design. The groove is milled on the bottom of the flat vapor chamber, and the heat pipe can be more closely attached to the vapor chamber of the vapor chamber. , not only can increase the contact area between the heat pipe and the vapor chamber, but also can effectively improve the heat dissipation efficiency. Compared with the traditional combination of heat conduction plate and heat pipe, this new patented heat sink design can withstand a heat dissipation load of 500W, Can reduce GPU temperature by up to 5°C.
In addition, the GDDDR6X display memory part dissipates heat through contact with a vapor chamber, while the power supply components dissipate heat through a copper plate connected with cooling fins, ensuring a stable power supply output for the graphics card.
The entire ASUS ROG Strix GeForce RTX 4080 OC Edition heatsink is integrated and fixed by a die-cast metal casing, frame and backplate, which provides an ultra-rigid structure to prevent the PCB from sagging or warping, so the entire graphics card weighs about 2387g.

▲ New enlarged axial three fans
The ASUS ROG Strix GeForce RTX 4080 OC Edition graphics card uses 3 new enlarged axial fans. The size of this generation Axial-tech fan has been increased from 100mm to 104mm. Double ball bearings increase the air flow by 23.8% and the air pressure by 19.3% compared with the previous generation. At the same time, it is equipped with a forward and reverse fan design, which can reduce the turbulent flow between adjacent fans and increase the airflow pressure, which can drive more airflow through the heat dissipation Fins and provide better cooling performance. At the same time, it is equipped with a 0dB fan control system. When the GPU temperature is lower than 50°C, the fan will automatically stop running, providing the best experience with zero noise.
Equipped with a hollowed-out metal backplane design, the extended part of the heat dissipation fins and the perforated backplane allow airflow to pass through, which can improve the heat dissipation effect.
