Water cooling on graphics cards has always been more of a niche section of the GPU market, but it seems to be becoming more popular. Most Nvidia partners have implemented some sort of water cooling in their lineups whether it be an AIO or a custom block, some have even included both. Colorful had already implemented the AIO on the RTX 3090 and RTX 3080 with the Neptune model, but are now adding an AIO to GeForce RTX 3070.

Whenever people look to buy a graphics card with an exotic cooling solution preinstalled, they look at the top models which for the case of Nvidia are the RTX 3090 and RTX 3080, so Nvidia partners only focus on putting a custom cooling solution on those cards, but Colorful has found a space that no other manufacturer fills. Colorful has added a water-cooled GeForce RTX 3070 to its lineup to fill a niche void in the market.
