Modder retains RTX 4090 and i9-13900K under 30C utilizing an air conditioner

WTF?! Modders have used numerous means to take PC cooling to new lows. Liquid nitrogen is well-liked for overclocking benchmarks, however different notable instruments embrace giant quantities of copper, dozens of toes of water block tubing, and a blizzard. One tinkerer has determined that the subsequent step is to make use of an air conditioner designed to chill a complete house.

A latest Bilibili video from modder “Electrolytic Sodium Carbonate” (ESC) demonstrates how an air conditioner can interface instantly with a PC tower. Though the tactic is probably going wildly inefficient, it retains each part extraordinarily cool.

Our overview of the GeForce RTX 5090 reveals it reaches noticeably increased temperatures than its predecessor regardless of the revolutionary cooling system Nvidia used for the brand new flagship’s founders version reference mannequin. Based on machine translation from Tom’s {Hardware}, ESC wished to organize for the brand new GPU king with a brand new over-the-top cooling system, testing it on a 4090.

The modder has a number of ridiculous cooling apparatuses linked to PCs all through her house, together with a thick water block with a number of tubes. Nevertheless, ESC bought and modified a brand new Xiaomi KFR-35GW air conditioner, linking it to her take a look at system with a liquid cooling reservoir. The 12,000 BTU AC unit attracts over 1,000 watts and measures 765 x 268 x 550mm, towering over the rig it is linked to.

Though the customized setup goes past overkill, the outcomes are spectacular. Each take a look at system part, together with the RTX 4090 and Intel Core i9-13900K, stayed underneath 30 levels Celsius throughout a 40-minute battery of benchmarks that included FurMark and AIDA System. The CPU core temperatures solely rose by a few levels. Later, outside testing noticed the GPU rise to simply 36C.

Benchmarks with the i9-14900K and RTX 5090 are forthcoming, however these early outcomes outperform earlier uncommon cooling options. As an example, putting in beneficiant quantities of copper, whether or not in bars or a big block, solely retains CPU temperatures roughly inside the 70s and 80s Celsius, however this technique ensures complete silence. Working 100 toes of tubing and a gallon of coolant can maintain a GPU underneath 30C and a CPU round 40C underneath load.

One of many solely issues that may beat a kilowatt air conditioner is a historic blizzard, which one other Bilibili modder, Baka, demonstrated in 2023. With passive cooling, an RTX 4090 uncovered to a -63 Fahrenheit (-52C) winter storm ran at -40C whereas the accompanying i9-13900K maintained 15C at 6.18GHz.
