Asetek has teamed up with MSI and MouseComputer to reveal a custom water cooled graphics card at Tokyo Game Show 2026. The Mouse Original NVIDIA GeForce RTX 5070 Liquid Cooled Overclocked Edition pairs a custom 240 size radiator with full GDDR7 memory coverage for maximum thermal headroom. Japanese buyers will only be able to acquire the card inside prebuilt G TUNE gaming desktops.
Standard graphics cards often run hot during prolonged gaming sessions. This custom cooling system aims to eliminate thermal bottlenecks completely. The 240 all in one liquid cooling block features an enlarged cold plate that makes direct contact with both the GPU die and the surrounding GDDR7 memory chips. While the standard GeForce RTX 5070 operates at a default power target of 250W, this custom cooling assembly can handle up to 300W of heat dissipation. That extra 50W capacity gives users substantial headroom to sustain higher clock speeds without thermal throttling.
Liquid cooling pumps can sometimes produce irritating high frequency sounds in quiet rooms. Asetek addressed this issue with a motor assembly that uses an 8 pole layout and a 7 blade impeller. Official acoustic tests reveal the pump produces 27 dB(A) of sound at a distance of 25 centimeters, which drops down to 20 dB(A) at 1 meter. Under a full 250W gaming load in a 35 degree Celsius room, total operating noise stays around 30 dB(A). It is an exceptionally quiet thermal setup for a factory overclocked card.
Individual PC builders will not be able to purchase this graphics card as a standalone component on retail shelves. MouseComputer is keeping the hardware exclusive to its line of G TUNE prebuilt gaming systems. This approach provides desktop buyers with a turnkey solution that includes factory tuned liquid cooling right out of the box.
