High-end AMD Threadripper Pro 9995WX processor successfully modified with BMW M4 radiator and Toyota Highlander fans; massive pump at 1,200 liters per minute fails to compete with liquid nitrogen cooling.
In a groundbreaking experiment, Chinese TechTuber Geekerwan has demonstrated an impressive aftermarket cooling solution for the AMD Threadripper Pro 9995WX, a high-power CPU with 96 cores and a TDP of 350W that can spike to around 1000W under overclocking conditions.
The most effective cooling method documented so far is a custom water cooling loop, utilizing a large car radiator from a BMW M4 and a high-flow automotive pump and fans from a Toyota Highlander 4x4. This unconventional approach provides vastly improved heat dissipation, surpassing the performance capabilities of conventional PC-specific AIO or air coolers.
The BMW M4 radiator, measuring approximately 600 x 350 mm, offers almost five times the surface area of a standard large AIO radiator. The high-capacity automotive pump can move 1,200 liters per hour (20 liters per minute), far surpassing the flow rates of typical PC water pumps. The cooling is further enhanced by oversized Toyota Highlander 30 cm diameter fans, each consuming 100W, much larger and more powerful than standard PC fans.
This setup successfully cooled the Threadripper 9995WX and enabled overclocking all 96 cores to 4.9 GHz, a remarkable feat considering the heat generation and power draw. However, Geekerwan's "super water cooling" setup failed to break the 5.0 GHz all-core mark due to the interface between the CPU cores and the AIO system.
Despite this, the experiment sets a high bar for cooling performance in extreme workstation CPU scenarios. It's important to note that implementing this solution requires significant modification and technical skill.
The AMD Threadripper Pro 9995WX, priced at $11,699, is the world's fastest workstation processor according to AMD. Geekerwan removed the radiator and pump from his BMW M4 for testing, and the video of the experiment can be viewed on his channel, starting around 7 minutes.
While consumer CPUs like the Ryzen 9 9950X are still superior to a Threadripper for gaming, according to Geekerwan, there may be exceptions where a Threadripper performs better, such as in Cities: Skylines 2. The Threadripper Pro 9995WX does not come bundled with a cooler, making aftermarket solutions like Geekerwan's all the more important.
Geekerwan's video highlights Uncle Tony's video of the Threadripper Pro 9995WX being tested under liquid nitrogen cooling. The English closed captions are available for Geekerwan's video, making it accessible to a wider audience.
In summary, for a CPU as power-hungry and thermally demanding as the Threadripper Pro 9995WX, the most effective aftermarket cooling solution currently documented is a custom water cooling loop utilizing a large car radiator and high-flow automotive pump and fans, far exceeding the performance capabilities of conventional PC-specific AIO or air coolers.
This custom water cooling loop, utilizing a large car radiator and high-flow automotive pump and fans, showcases an impressive aftermarket cooling solution for high-power CPUs like the AMD Threadripper Pro 9995WX. Unconventional technology from automotive parts surpasses the performance capabilities of conventional PC-specific AIO or air coolers.
