In a remarkable display of ingenuity, a Chinese tech enthusiast has successfully cooled an NVIDIA RTX 4090 graphics card to a chilling 20°C using a standard household air conditioning unit. This innovative setup not only showcases the potential of unconventional cooling methods but also sets the stage for future testing with the upcoming RTX 5090.
Key Takeaways
- A Chinese tech enthusiast has cooled an RTX 4090 to 20°C using a household air conditioner.
- The cooling system utilizes a 12,000 BTU air conditioning unit.
- The setup is designed for future use with the RTX 5090, pending the release of a compatible water block.
- The cooling method demonstrates the potential for extreme overclocking and performance enhancement in gaming PCs.
The Setup
The cooling system was created by a tech content creator known as “Electrolytic Sodium Carbonate” on the Chinese platform Bilibili. The setup features a Xiaomi KFR-35GW air conditioning unit, which is capable of producing 12,000 BTUs of cooling power. This air conditioner is connected to a liquid cooling system that circulates coolant through the RTX 4090 and an Intel Core i9-13900K processor.
The air conditioning unit operates at a power draw of approximately 1.2 kW, which is significantly higher than typical PC cooling solutions. Despite its size and power consumption, the results have been impressive, with the GPU maintaining a temperature of just 20°C during a rigorous 40-minute stress test.
Performance Under Stress
During the stress test, which utilized tools like FurMark and AIDA System Stability Test, the RTX 4090 demonstrated remarkable thermal performance:
- Idle Temperature: 2°C
- Load Temperature: 20°C
- Hotspot Temperature: 36°C
These results indicate that the cooling system is not only effective but also capable of handling the demands of high-performance gaming and computing tasks.
Future Prospects
The creator plans to upgrade the system to accommodate the upcoming RTX 5090, which will feature an Intel i9-14900K processor. The current setup is a temporary measure, as the necessary water block for the RTX 5090 is not yet available. Once the upgrade is complete, it will be fascinating to see how the cooling system performs with the next-generation GPU.
Conclusion
This innovative cooling solution exemplifies the creativity and resourcefulness of PC enthusiasts. By repurposing a household air conditioning unit for computer cooling, the tech enthusiast has not only achieved remarkable thermal performance but also opened the door for future advancements in PC cooling technology. As the gaming community eagerly awaits the RTX 5090, this setup serves as a testament to the lengths enthusiasts will go to push the boundaries of performance.
