Question about NZXT Kraken G12

NO. The Asus 3070 Dual, like all 3000 series cards considered so far, has VRMs on both sides of the processor, the G12 is designed for graphics cards that have the VRMs only on the outer side (like the 1000 and 2000 series), so it has only 1 fan that is supposed to ventilate exactly these VRMs. In principle, it is almost always possible to mount an AIO CLC on a card and ventilate the VRMs with fans, but this requires manual tinkering, which is exactly what the G12 is supposed to save.
