The graphics card does not have a reference design. The AIO for your GPU is expected to be available in the shop from July. If you want to build a DIY water cooler, this is the cooler that is already available: Alphacool Eisblock Aurora RTX 3080/3090 Gigabyte Gaming/Eagle Wasserkühler | Nvidia Fullsize | Grafikkarten Wasserkühler | Shop | Alphacool - the cooling company
Thanks so much for the fast answer and I'll plan accordingly with September ?Hi @xenon, probably in September (but without guarantee) ;-)
