Water-cooled Asus ROG Matrix RTX 4090 GPU has massive 360mm radiator

With liquid metal thermal interface material and a triple-fan cooler, Asus claims this is the fastest Nvidia RTX 4090 you'll soon be able to buy.

Asus has unveiled the Asus ROG Matrix GeForce RTX 4090 Platinum 24GB GDDR6X, a new water-cooled graphics card that features a massive 360mm radiator. So cool does this keep the card that Asus has been able to crank up the GPU clock speeds enough to claim this is the fastest Nvidia GeForce RTX 4090.

Asus hasn’t put any figures on those boosted clock speeds yet but the water-cooled RTX 4090 can switch between a 450W (Q-BIOS) power mode and 600W (P-BIOS) power mode.

Along with its massive 360mm radiator, the Matrix card uses a custom cold plate that pulls heat from the VRMs and VRAM, as well as the GPU die. The plate also uses liquid metal thermal interface material for the absolute best thermal conductivity possible – it’s roughly ten times more conductive than typical thermal paste.

Three ROG MF-12S ARGB fans are then attached to the radiator to quietly blow heat from your system. Unlike the MSI liquid cooler concept demonstrated recently, the radiator is separate from the card so can be mounted anywhere in your case.

Along with its exotic thermal deign, the ROG Matrix RTX 4090 has exotic styling too. The card, which was announced at Computex 2023, is framed by a thick metal section that towers high above the PCIe bracket and also stretches to be 2.5 slots thick but it leaves its back section open where the pipes leave the cold plate, allowing for better airflow around the card.

The ROG Matrix RTX 4090 also has some clever software features, including a thermal map feature that’s linked to several temperature sensors attached to the card. You can also switch between those bios modes for quiet or performance modes.

With a likely Asus ROG Matrix RTX 4090 release date of Q3 2023, the Asus ROG Matrix RTX 4090 price is not yet known but is likely to be over $2,500, if not closer to $3,000. That’ll put it out of the reach of most buyers but will almost certainly means it tops the charts in our best graphics card list.
