(Image credit: TrashBench / YouTube) GPU overclocker TrashBench set a world overclocking record on an Intel Arc B580 GPU with a relatively simple setup. Instead of employing exotic solutions like liquid nitrogen, used by other overclockers to hit world records, he instead slapped on a pond pump and filled the custom loop with a 50/50 glycol mix of vehicle antifreeze that had been pre-chilled in a freezer. To his surprise, the GPU hit an incredible -17 degrees Celsius (that’s 1.4 degrees Fahrenheit), allowing him to push the performance of Intel’s top-of-the-line consumer GPU. According to the YouTube video , the car-coolant-chilled graphics card achieved a 3DMark Time Spy score of 16,631 — some 12% higher than a stock GPU, breaking the world record for the B580.
The mods TrashBench made to the GPU were rather simple, with the most complicated part being 3D-printing a custom mount to secure the water block. Trashbench notes that antifreeze remains liquid until roughly -25C, and he chilled the liquid in his freezer, which took it down to -17C. From there, he ran a couple of flexible tubes into an open cooler containing the pre-chilled glycol mix and turned on the pump to circulate it, allowing the graphics card to reach sub-zero temperatures.
