The latest high-performance CPU from AMD requires a robust cooling system to maintain its operating temperatures. The Threadripper 9995WX Pro is no exception, demanding massive power and heat dissipation capabilities. To stay within safe limits, users often “overclock” their CPUs, which increases heat production.
In search of an unconventional solution, Chinese YouTuber Geekerwan turned to his BMW F82 M4’s cooling system. He repurposed the radiator, water pump, and fans from his car to create a makeshift cooling rig for his CPU. The idea is that the BMW M4’s cooling performance is among the best in the world.
However, during benchmarking, the results were disappointing. The CPU failed to reach its peak performance of 5.0MHz, instead capping out at 4.9MHz. The radiator remained cool during testing, but it was a hardware issue – the CPU’s power consumption exceeded its power supply’s capacity, and the cooling linkage wasn’t designed for such high demands.
This unusual experiment showcases the creativity and resourcefulness of PC enthusiasts in addressing extreme cooling challenges. For those interested in watching Geekerwan’s full video, it can be found on YouTube with subtitles available in Chinese.
