NVIDIA's latest RTX 4000 series graphics cards feature a redesigned cooling system marketed as "twin axial flow through thermals". This design draws air in from the outer side and vents it from the top and connection port sides, with an upgraded fan design that improves on its predecessor.
While the absence of RGB lighting may disappoint some users, the GeForce RTX logo glows white, adding a touch of elegance to the card's aesthetics. Despite not incorporating the new DP 2.1 standard yet, the RTX 4000 series graphics cards come with HDMI 2.1 and DisplayPort 1.4 ports that support 8K 60 Hz HDR via a single HDMI cable. The card's IO panel features an air vent with connectors and an aluminium fin stack housed within an alloy frame.
The fin stack is responsible for the majority of the cooler's volume, with the first fan drawing in fresh air and venting it from the card's sides, while the second fan pulls air through the fin stack and vents it upward. Additionally, six heat pipes connect the various cooling elements to a vapour-chamber plate, which effectively removes heat from the GPU and memory.
The cards also include a 12VHPWR power connector header, with a converter cable that feeds from three 8-pin connectors. The package includes documentation and an adapter that converts the 8-pin PCIe power inputs to a 12-pin power connector. It is recommended to keep a 3-4cm distance from the plastic connector and avoid bending the cable too close to it.
