This blower type design is a full custom one. Gigabyte even modified display connectors to dual DisplayPort 1.4a and dual HDMI 2.1, while most samples only offer one HDMI port.

VideoCardz got its hands on a bunch of photos of the GIGABYTE GeForce RTX 3090 TURBO. So far, this is the only known Ampere-based video card that uses a simple blower-style cooler. The card uses just two slots and has two vertically placed 8-pin PCIe power connectors. It doesn't look like this model will be factory overclocked. It will be interesting to see what temperatures (and noise levels) this cooler gets on a 350W TDP card.
