They make my exact card both air/liquid cooled (the 4090 suprim 24G by MSI)
Air Cooled: 336x142x78mm
Liquid: 280x140x43mm
basically it's considerably shorter and almost half as thick.
granted the liquid does obviously use an external radiator similar to the cpu one (they're actually pretty much the exact same), mine I replaced two of my three front fans with the radiator setup.
