Gigabyte also wants to offer the Geforce RTX 4090 with compact water cooling: The RTX 4090 Aorus Waterforce combines Nvidia’s flagship with a 360 mm radiator. The model apparently largely corresponds to the already available variant based on the RTX 3090 Ti.
With Nvidia’s new RTX 4000 graphics cards, there should be a significant leap in performance, but consumption will probably increase at the same time. While the direct predecessor, the Geforce RTX 3090, came onto the market with a TDP of 350 watts, the Geforce RTX 4090 is said to be on the market with 450 watts. This puts it in the same category as the drunk Geforce RTX 3090 Ti, and accordingly, huge coolers should again be necessary to keep the GPU at the right temperature.
Lots of cooling surface for the RTX 4090
Depending on how difficult it is to cool the built-in AD102 GPU in the end, water-cooled graphics cards could become more popular. The board partners are already positioning themselves for this: in addition to other companies, Gigabyte apparently also wants to offer a corresponding graphics card. According to the Videocardz website, the Geforce RTX 4090 is planned, among other things, as an Aorus Waterforce model that will use a 360 mm radiator. Previously shown custom designs from other manufacturers, on the other hand, only use 240 mm radiators.
It’s officially confirmed Gigabyte RTX 4090 Aorus Waterforce not yet: On the Company product page is so far only the Aorus RTX 4090 Master listed. The leak from Videocardz still seems realistic, because in the form of the Aorus RTX 3090 Ti Waterforce there is already a similar model. Compared to this, the variant based on the RTX 4090 should undergo minor changes, but on the whole the cooler apparently remains identical.
As can be seen from the leaked images, the backplate for the Gigabyte Aorus RTX 4090 Waterforce, for example, again has an NVLink cutout, although the RTX 4090 does not support this interface at all. Gigabyte probably simply took over the cooler of the RTX 3090 Ti unchanged. The only visible difference would be an additional “GEFORCE RTX” imprint on the side, which could probably be added later in production without any problems.

According to the leaked images, no changes can be seen on the radiator of the Gigabyte Aorus RTX 4090 Waterforce either. With the three built-in 120 mm fans, there should be sufficient cooling capacity for the AD102 GPU without any problems. Only potential new hotspots on the chip could become problematic. In general, however, the power density has not increased drastically: In the same TDP class, the AD102 GPU is only around three percent smaller than the GA102 chip of the RTX 3090 Ti.
