Palit showcases their hybrid-cooled RTX 4090 Neptunus GPU at Computex

Meet the RTX 4090 Neptunus, a hybrid air-cooled/liquid-cooled GPU from Palit and Bitspower

Palit and Bitspower have joined forced to create a custom, hybrid cooled, RTX 4090 graphics card called the Neptunus. This GPU features a custom hybrid cooling technology with a “patentent AquaFusion Copper Base”. This graphics card can work with or without the liquid cooling. That means that owners can enjoy their new RTX 4090 before they invest in their liquid cooling loop.

If you ignore this GPU’s Bitspower liquid cooling ports, the graphics card looks a lot like Palit’s existing RTX 4090 Game Rock graphics card. The GPU features a 3-fan heatsink design that appears to be around 3.5 PCIe slots in size. Even without liquid cooling, this is a capable heatsink. That said, the addition of liquid cooling does make it more effective.

Palit has stated that their Neptunus liquid cooler will drop temps by 10+% when used with liquid cooling. Sadly, we were not able to see the operating temperatures of this graphic’s card on the show floor.

The RTX 4090 Neptunus is a great-looking graphics card, and its liquid cooling support is a neat bonus. Sadly, we do not know when this GPU will make it to market, or how much it will cost when it does.
