Summary
The MSI RTX 5090 SUPRIM LIQUID X SOC presents itself as an uncompromising variant of the GeForce RTX 5090 optimized for performance and thermal stability and combines factory overclocking with a hybrid cooling system that relies on an all-in-one water cooling system with 360 mm radiator and three fans. The additional ventilation of the PCB with a shroud fan completes the overall concept and ensures low temperatures under load.
Even the first glance at the BIOS reveals the factory design for maximum performance in gaming mode, while silent mode is optimized for lower noise emissions with minimal performance loss. The clock rates reach over 2850 MHz in gaming mode and also remain far above the Founders Edition in the silent profile. In both modes, the temperature development of the GPU remains stable and moderate even under prolonged loads. The memory chips do not reach critical values even under synthetic full load, which is due to a consistent cooling structure and the subsequently used thermal compound (Thermal Grizzly TG Advance), which was used instead of pads in this case. The homogeneous distribution and the fixed contact pressure enable the heat loss to be dissipated evenly.

Thermographic images confirm this picture. The temperatures at the VRM, hotspot and memory remain controlled, whereby a slight temperature advantage can be seen in gaming mode. The GPU temperature remains below 60 °C even under full load, while the hotspot area at the VRM phase shows a typical peak value for the power consumption with a maximum of 83 °C, without jeopardizing the thermal integrity. The idle recording with the Optris Pi640 also shows a consistently cool board with all measuring points well below 40 °C, which speaks for the efficiency of the fan curve and the waste heat distribution.
Special attention is paid to the fans. Two separate fan groups, each with their own characteristics, create a noise pattern that is difficult to evaluate objectively. While the radiator produces an airflow noise typical of AIO solutions, the shroud fan produces a low-frequency hum. The control is cleanly tuned without audible load changes or speed jumps. Silent mode offers audibly quieter operating behavior with significantly reduced speed and better overall noise characteristics.
The power consumption reaches peak values of up to 600 watts in gaming mode, which makes a power supply selection of 1000 watts or more with ATX 3.1 compatibility and a 12V 2×6 connector indispensable. The power supply should be designed for the load peaks that occur, as sudden changes between load states are particularly demanding on the power supply.
Ultimately, the RTX 5090 SUPRIM LIQUID SOC is a sophisticated high-end card for users with the highest demands in terms of performance, temperature behavior and optical control. The combination of an efficient water cooler, active PCB ventilation, high power consumption and effective memory cooling results in a coherent overall package that is both technically and thermally impressive. If you have the necessary space and a suitable power supply unit, you get a card with great boost potential, high efficiency and stable background noise.
