Recently, blogger Trashbench installed an Arctic WS360 360mm server-grade all-in-one water-cooling radiator directly onto the GeForce RTX 3080 graphics card. After modification, the data shows:The memory temperature plummeted from 104°C to 50°C, a drop of up to 54°C, the core temperature dropped by 26°C, and the core hotspot temperature dropped by 39°C.
Arctic WS360 was originally designed as a cooling solution for large workstation CPUs. Its copper cold plate area is more than twice that of ordinary consumer-grade water cooling.
This large cold plate can completely cover the GPU core of the RTX 3080 and all surrounding GDDR6X memory particles. After installation, the visual effect even looks like the original factory design.
However, because the cold plate was too large, it completely blocked the standard mounting holes for the graphics card. After more than ten trials and errors, Trashbench finally customized a set of exclusive fixing brackets through 3D printing to complete the installation.
In the 3DMark Time Spy test, the modified RTX 3080 can reach the extreme overclocking performance level of the air-cooled version at the default frequency, with lower power consumption.
After manual overclocking, the core frequency increased by an additional 195MHz, and the average performance increased by about 9% compared with the air-cooled original version. This result is close to the performance ceiling without flashing the BIOS or performing shunt modifications.
