Ambitious modder bolts a 360mm server AIO onto an RTX 3080, slashes VRAM temps in half — enormous workstation cooler powers 54 degree drop, 9% performance uplift

A screenshot from a Trashbench video showing the Arctic WS360 successfully mounted on the operational GeForce RTX 3080 graphics card.

We love a beautifully unhinged cooling mod, and Australian overclocker and YouTuber Trashbench is arguably the champion of the genre. We've previously covered his exploits, like leveraging a camping chiller to aggressively overclock an RTX 5050, but in this latest video, Trashbench decided to take an Arctic WS360 360mm server AIO cooler and strap it directly to a GeForce RTX 3080. The result? A massive, aesthetically pleasing mod that halves the card's VRAM temperatures and offers impressive efficiency gains.

See, the Arctic WS360 is built for massive workstation CPUs. That means its copper cold plate is more than twice the size of a standard consumer liquid cooler. Surprisingly, this massive footprint makes it almost ideal for a modern GPU, as the cold plate is large enough to completely cover both the GPU core and the surrounding GDDR6X memory modules, slotting almost perfectly between the rows of VRM components. Once installed, it looks remarkably stylish, almost as if it were engineered specifically for the 3080.
