How a BMW M4 Radiator Cooled a Powerful Computer Processor  - 1

Imagine trying to cool an extremely powerful computer processor – so powerful that it has 96 cores. That's exactly what the Geek Bay team did with AMD's new flagship, the Ryzen Threadripper Pro 9995WX. Instead of using standard computer cooling, they decided to resort to something quite unusual: a radiator from a BMW M4 sports car.

The experiment aims to "overclock" (make the processor run faster than its factory settings) all 96 cores to 4.9 GHz. To achieve this, they not only use a car radiator, which is quite large (600 by 350 mm), but also a water pump, again taken from a BMW M4, which can move about 1200 liters of water per hour. To cool this huge radiator, they also installed a large 300mm fan from a Toyota Highlander, which provides a huge flow of air.

The result? The processor managed to achieve an impressive 187,153 points in the Cinebench R23 test, which is an indicator of its computing power. However, this is lower than the world record set with extreme liquid nitrogen cooling, where the frequency was 5.8 GHz.

Interestingly, this entire overclocking process resulted in a power consumption of over 2000 watts. This huge consumption was so great that it even damaged the 1600 watt power supply that was used. This experiment shows how important an effective cooling system is when working with high-performance components and how far one can go in the pursuit of maximum power.
