NVIDIA re-uses its twin axial flow-through thermal system. This design involves drawing air from the sides and expelling it through the top and connection ports. The RTX 4080 SUPER Founder Edition features an improved fan design compared to the RTX 3080 FE series, focusing on efficiency without incorporating too much LED lighting. The only visual accent is the white-lit GeForce RTX logo.

The RTX 4000 series, including the RTX 4080 SUPER, offers HDMI 2.1 and DisplayPort 1.4 ports. Notably, NVIDIA has not adopted the newer DisplayPort 2.1 standard. The I/O panel doubles as an air vent, with connectors supporting 8K 60 Hz HDR output via HDMI.

As stated, the card looks beautiful in that dark design. You're going to notice that overall performance is within 1 maybe 2% from the original 4080, this is due to the same TGP of 320W. The card's length is give or take 30cm.

The card's structure comprises an alloy frame enclosing an aluminum fin stack, which forms a significant part of the cooling apparatus. Airflow is managed by two fans: the first draws air in and expels it sideways, while the second fan pulls air through the fin stack and directs it upwards. For cooling often the thumb of rule is the more heavier the better the cooling, and at 2100g we can expect very decent cooling.

The cooling mechanism integrates heat pipes that link to a vapor-chamber plate. This plate efficiently dissipates heat from the GPU and memory modules. Another notable feature is the inclusion of the 12VHPWR power connector, a point of discussion in the tech community.

The RTX 4080 comes with a converter cable, converting three 8-pin connectors to a single 12-pin connector, and documentation is provided for this setup. Users are advised to maintain a 3-4 cm distance from the plastic connector to avoid bending the cable excessively. The package includes detailed images of the RTX 4080's PCB and its configuration in a testing environment.
