A typical computer is made up of a processor — or a CPU (central processing unit) — and a cooling system, usually an air-cooled heatsink or a liquid-cooling loop with a radiator
The former is a simpler design but doesn't cool as effectively as a liquid-cooling system.

As computer hardware, particularly CPUs and GPUs, continues to demand more power, the necessity for a more powerful cooling system become crucial. This is especially true for behemoths like the high-end RM57,000 AMD Threadripper PRO 9995WX processor .

One enthusiast went to great lengths in his quest to cool his computer's CPU
Enter Geekerwan, who threw convention out the window and swapped his liquid-cooler for an actual car radiator. Because, well, why not push the limits?
Geekerwan cobbled together a cooling system using a radiator pulled from a BMW M4 sports car and a pair of fans from a Toyota Highlander SUV, which is approximately five times larger than a computer liquid cooling solution.
And just to show how absurd this setup really is, here are the numbers
This custom radiator boasts a pump capable of a whopping 1,200 litres per hour (LPH) flow rate — that's almost ten times what you'd get from even high-end 360mm cooler.
So, Geekerwan used 300mm fans borrowed from a Toyota Highlander. These beasts are rated at 100W and deliver a truly colossal amount of airflow, absolutely getting the job done.
And the results? Simply mind-blowing. They managed to push all 96 CPU cores to an incredible 4.9GHz, culminating in an astonishing 187,153 points in Cinebench R23.
However, it still falls well short of the world record
The world record currently stands at 5.8GHz across 100 cores. So, how did this car radiator-cooled CPU lose?
The setup caused an instant power surge, with the Threadripper 9995WX CPU guzzling over 2,000W. For comparison, most desktops draw just 65-250W, and laptops? Barely 15-100W.
Interestingly, despite this massive heat generation, the car radiator system isn't actually optimised for super-quick CPU cooling. Yet, the sheer thermal capacity of that car radiator meant it still managed to stay surprisingly cool, absorbing all that heat even if not at lightning speed.
