- Ultra -low GPU temperatures sound impressive until you consider the power bill
- The cooling of a GPU with a CA unit can work, but the size and risks are not very practical
- A 12,000 BTU AC for GPU cooling: it works, but at what cost?
A Chinese Techtuber has integrated an air conditioning unit of 12,000 BTU in the fluid cooling system of the RTX 4090 processor and an Intel Core I9-13900K processor.
The ESC configuration replaces a conventional PC radiator with a domestic air conditioning unit. The Xiaomi Kfr-35GW air conditioning serves as a primary component of the cooler, while the system directs the cold liquid through a loop connected to the PC.
ESC plans to match an Intel Core I9-14900K processor matched with the incredibly elusive Nvidia GeForce RTX 5090 GPU, but the lack of a block of water available for the RTX 5090 has put a shock absorber of – Ahem – in that.
AC + CPU + GPU = Ru ok?
In the initial tests, the RTX 4090 maintained a temperature of only 20 ° C under stress tests. When the air conditioning unit moved outdoors, the temperatures of the GPU remained exceptionally low, reaching 2 ° C to inactive and 20 ° C under load.
Then, air conditioning cooling demonstrates an impressive cooling performance, but there are several practical concerns.
First, the integration of an HVAC system into a PC is a process involved, which implies welding, refrigerant management and personalized pipes. That is not suitable for the average user and introduces risks related to the management of refrigerant gases and electrical components. In case you even want to try this at home; No.
Another concern is energy consumption. The air conditioning unit in this configuration generally attracts around 1.2 kW of power, which is significantly higher (and more expensive) than traditional PC cooling solutions.
Extreme cooling can lead to condensation, which raises a serious risk for the longevity of the workstation components; Without adequate insulation and moisture control, the system could suffer unwanted damage due to an accumulation of water in the chassis.
Also consider the size of the CA unit, which measures 765 x 268 x 550 mm, significantly larger than a 360 mm PC cooling radiator and even larger than the PC tower that is cooling. It is incredibly not very practical, so I cannot see this as anything other than a click bait hobbing project.
