Liquid-cooled RTX 3090 Ti for 4K creators
This ROG STRIX card pairs a factory-overclocked GeForce RTX 3090 Ti GPU with a 240 mm hybrid cooler, delivering 24 GB of GDDR6X memory on a 384-bit bus for 4K gaming and GPU-accelerated workloads. The PCIe 4.0 interface and 10752 CUDA cores provide the throughput needed for high-resolution rendering and AI-assisted content pipelines.
Upgrade from air-cooled 3090 when thermals limit
Moving from a standard air-cooled RTX 3090 or earlier flagship becomes worthwhile when sustained boost clocks throttle under load, as the full-coverage cold plate and 560 mm tubing keep the GPU die and memory at lower temperatures. The 1980 MHz OC boost and 21 Gbps memory speed are maintained more consistently, reducing frame-time variance in long sessions.
Suits 4K enthusiasts with 1000 W PSU and EATX space
Builders running a 1000 W supply with a 16-pin connector and an EATX chassis that fits a 240 mm radiator will gain quiet, high-frequency operation for 7680 x 4320 output across four displays. Compact cases without radiator clearance or systems below the recommended power budget should consider air-cooled alternatives instead.

Questions sur cet article
Will the 293 mm card and 240 mm radiator fit in my EATX chassis?
The card measures 293 mm long and occupies 2.6 slots. The 240 mm radiator is 10.71 x 4.76 inches, and 560 mm tubing allows flexible placement in EATX cases.
How do I install the hybrid cooler without bending the 560 mm tubing?
Mount the radiator and fans first, then lower the cold-plate onto the GPU die and memory. Route the 560 mm tubes with gentle curves — sharp kinks restrict flow and are the most common error.
When should I plan to replace the liquid-cooling loop on this 450 W card?
A sealed 240 mm loop typically runs 3–5 years before coolant degradation or pump wear. Monitor GPU temperatures under 450 W load; rising deltas signal replacement time.
