- Ultra-Low GPU Temps sounds impressive until you consider the power bill
- To cool a GPU with an AC unit can work but the size and risks make it impractical
- A 12,000 BTU AC for GPU cooling: It works, but at what costs?
A Chinese TechTuber has integrated a 12,000 BTU climate system into the liquid cooling system in the RTX 4090 and an Intel Core I9-13900K processor.
ESC’s setup replaces a conventional PC-mounted radiator with a household conditioning device. The modified Xiaomi KFR-35GW climate system acts as the primary cooler component, while the system directs chilled liquid through a loop connected to the PC.
ESC is planning to pair an Intel Core i9-14900K processor paired with the incredibly evasive NVIDIA GeForce RTX 5090 GPU, but the lack of an accessible water block for RTX 5090 has put an – ahem – steamer on it.
AC + CPU + GPU = RU OK?
In initial tests, the RTX 4090 maintained a temperature of only 20 ° C during stress tests. When the air conditioner was moved outdoors, the GPU temperatures remained exceptionally low and reached 2 ° C at idle and 20 ° C under load.
So Air-Con cooling demonstrates impressive cooling performance, but there are several practical concerns.
First, it is to integrate a HVAC system into a PC an involved process involving welding, refrigerant control and custom pipeline. It is just not suitable for the average user and introduces risks related to handling refrigerant gases and electrical components. On Off -Chance you will even try this at home; Don’t do it.
Another concern is energy consumption. The air conditioning unit in this setup typically draws about 1.2 kW of power, which is significantly higher (and more expensive) than traditional PC cooling solutions.
Extreme cooling can lead to condensation, which pose a serious risk of the life of work station components; Without proper insulation and moisture control, the system could suffer from accidental damage due to a build -up of water in the chassis.
Also consider the size of the AC unit measuring 765 x 268 x 550 mm, significantly larger than a 360 mm PC cooling radiator and even larger than the PC tower, it is cooling. It is incredibly impractical and therefore I do not see this as anything other than a click-magn-hobby project.
