- Extremely-low GPU temps sound spectacular till you take into account the facility invoice
- Cooling a GPU with an AC unit may match, however the dimension and dangers make it impractical
- A 12,000 BTU AC for GPU cooling: it really works, however at what price?
A Chinese language techtuber has built-in a 12,000 BTU air-con unit into the liquid cooling system of the RTX 4090 and an Intel Core i9-13900K processor.
ESC’s setup replaces a standard PC-mounted radiator with a family air-con unit. The modified Xiaomi KFR-35GW air conditioner serves as the first cooler part whereas the system directs chilled liquid by means of a loop related to the PC.
ESC plans to pair a Intel Core i9-14900K processor paired with the extremely elusive Nvidia GeForce RTX 5090 GPU, however the lack of an accessible water block for the RTX 5090 has put a – ahem – dampener on that.
AC + CPU + GPU = R U OK?
In preliminary checks, the RTX 4090 maintained a temperature of simply 20°C below stress testing. When the air-con unit was moved outside, GPU temperatures remained exceptionally low, reaching 2°C at idle and 20°C below load.
So, air-con cooling demonstrates spectacular cooling efficiency, however there are a number of sensible considerations.
First, integrating an HVAC system right into a PC is an concerned course of, involving welding, refrigerant administration, and customized piping. That is simply not appropriate for the typical person, and introduces dangers associated to dealing with refrigerant gases and electrical parts. On the off likelihood you even need to do this at residence; do not.
One other concern is power consumption. The air-con unit on this setup sometimes attracts round 1.2 kW of energy, which is considerably greater (and costlier) than conventional PC cooling options.
Excessive cooling can result in condensation, which poses a severe danger to the longevity of workstation parts; with out correct insulation and moisture management, the system might endure from unintended injury as a result of a build-up of water within the chassis.
Contemplate, additionally, the scale of the AC unit, which measures 765 x 268 x 550mm, considerably bigger than a 360mm PC cooling radiator and even greater than the PC tower it’s cooling. It is extremely impractical, and so I can not see this as something apart from a click-baiting interest undertaking.
