Recently overseas blogger TrashBench showed off his crazy DIY immersion cooling device. Usually immersion cooling technology is mainly used in large-scale server environments.But TrashBench took matters into his own hands and submerged his graphics card in car transmission fluid instead of the mineral oil typically used in such attempts.
He used a large plastic box, placed a ROG Strix GTX 1060 PCB and heatsink into it, and connected it to an external motherboard via a PCIe extension cable.
Then he poured transmission oil into the container. In order to circulate the liquid, he installed a submersible pump in the container and connected it to an external pump to achieve the exchange of hot oil and cold oil, thus completing the first cycle.
The second cycle passes the hot oil above through a Dodge transmission cooler, which essentially acts as a radiator to cool the transmission oil.The cooled liquid flows back into the container to complete the cycle, a process very similar to the cooling mechanism inside a car.
TrashBench ran some benchmarks and the results showed a solid improvement of about 10% in various games and benchmarks, even reaching 16% in 3DMark.
Of course, this is mainly due to the 2190MHz acceleration frequency that the GTX 1060 can achieve in this environment, which is significantly improved from its default 1886MHz, and finally won the first place in the world for Fire strike.
He also added a 1080 Ti for testing. The 1080 Ti can already reach 1960MHz under air cooling, but under transmission oil cooling, its frequency increased to 2114MHz, and the performance increased by about 7%.
But it also ends up leaving a mess, and TrashBench specifically recommends not using transmission fluid, which stains everything and is difficult to clean because it seeps into every corner of the hardware.
