NVIDIA has added liquid cooling to its A100 GPU, designed for data centres and supercomputers. According to the company, this move reduces the A100’s energy consumption by 30 per cent. NVIDIA states that it will continue to work on liquid-cooled GPUs.
The increasingly digital world has increased the need for technological innovations such as supercomputers and data centres. However, such systems also increased energy consumption, which led to the search for alternatives. Now, NVIDIA has made an important development that will reduce the amount of energy used in data centres. The company has officially announced its own liquid-cooled GPUs. A100 GPUs, developed for data centres and supercomputers and have been actively used for several years, can now be purchased with liquid-cooled versions.
According to NVIDIA, data centres consume more than 1 per cent of all electricity in the world. 40% of this energy consumption is only for cooling the devices. Developing a solution for this, the company succeeded in making the A100 self-liquid cooled. The company states that the energy consumption of new GPUs is 30 per cent lower than previous versions.
Self-cooled GPUs may not be just the A100
NVIDIA’s statements led to the question of whether everyday users will one day have self-cooled GPUs. NVIDIA did not make a clear statement at this point. The company stated that it will continue to work on the liquid cooling integration of GPUs developed for data centres. But liquid-cooled GPUs have been discussed for some time already. In fact, AMD has patent studies on self-cooled graphics cards. In summary, we can say that NVIDIA will sooner or later add liquid cooling to GeForce RTX series graphics cards. So why did liquid cooling systems become so important when there were huge fans?
According to the statements of popular liquid cooling system manufacturer Asetek, liquids absorb heat much better than air. Moreover, transferring a heated liquid from one place to another in a controlled manner is much easier than transferring air. These two advantages directly bring liquid cooling systems to the fore. There is also the dimension of volume. Liquid cooling systems take up much less space compared to air cooling systems. This is also very important. Because engineers can integrate much more efficient liquid cooling systems into the space where they will place the air cooling systems. Being aware of these, NVIDIA seems to have begun to attach more importance to liquid cooling systems than ever before.
