ASUS has announced the TUF Gaming X3 Radeon RX 5700 series EVO graphics cards. This includes the SKUs "TUF 3-RX5700-O8G-EVO-GAMING" for the RX 5700, and "TUF 3-RX5700XT-O8G-EVO-GAMING" for the RX 5700 XT.

These new cards have a better cooling system in place than the original TUF Gaming RX 5700 series graphics cards, since tech reviewers heavily criticized them for bad cooling performance. Reacting to the criticism, ASUS improved cooling is due to the aluminum fin-stack heatsink, which is entirely different from the original TUF gaming cards.
