Galax has expanded its NVIDIA GeForce RTX 4090 graphics card lineup with a new Hydro models available in white or black - the latter will become available at a later date. The new design sports a 360 mm AIO liquid cooler with a triple-fan setup and 50 cm long tubing, which seems to be a first for Galax - all of its previously released GeForce RTX 40-series cards have been air-cooled. A full-cover aluminium alloy backplate is attached, according to Galax's product page.

It is not clear where the RTX 4090 Hydro cards sit in Galax's model rankings, but the pair look to be positioned below their flagship air-cooled HoF (Hall of Fame) sibling. The HoF boasts a 2595 MHz boost clock plus a 1-Click OC Clock of 2610 MHz (enabled via Galax's software), while the Hydro makes do with a 2580 MHz boost clock which aligns it with the 4090 SG 1-Click OC (air-cooled) variant, but the specification sheet points to the Hydro missing Galax's software-enabled overclock feature.
