- Ultra-basic GPU temperatures are impressive until you consider the power bill
- The cooling of 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 price?
A Chinese techtuber has integrated a 12,000 BTU air conditioning unit in the RTX 4090 liquid cooling system and an Intel Core i9-13900K processor.
The ESC configuration replaces a conventional radiator mounted on PC with a domestic air conditioning unit. The modified air conditioner Xiaomi KFR-35GW serves as a main component the main cooler while the system directs the refrigerated liquid through a loop connected to the PC.
ESC is planning to associate an Intel Core i9-14900K processor associated with the NVIDIA GeForce 5090 GPU incredibly elusive, but the lack of water block available for the RTX 5090 has put a – AHEM – depreciating on it.
AC + CPU + GPU = RU OK?
In initial tests, the RTX 4090 maintained a temperature of only 20 ° C in stress test. When the air conditioning unit was moved outside, GPU temperatures remained exceptionally low, reaching 2 ° C in slow motion and 20 ° C under load.
Thus, air cooling shows impressive cooling performance, but there are several practical concerns.
First, the integration of a CVC system into a PC is an involved process, involving welding, refrigerant management and personalized piping. This is simply not suitable for the average user and has risks linked to the handling of refrigerant gases and electrical components. If you even wanted to try this at home; don’t do it.
Another concern is energy consumption. The air conditioning unit of this configuration generally attracts approximately 1.2 kW of energy, which is much higher (and more expensive) than traditional PC cooling solutions.
Extreme cooling can lead to condensation, which represents a serious risk for the longevity of the components of the workstation; Without a correct control of insulation and humidity, the system could suffer from involuntary damage due to an accumulation of water in the chassis.
Also consider the size of the AC unit, which measures 765 x 268 x 550 mm, much larger than a 360 mm PC cooling radiator and even larger than the PC tower, it cools. It’s incredibly impractical, so I don’t see that as something other than a hobby project.
