According to a press release issued by Asetek, the company has been granted a patent related to liquid cooling graphics cards. The release didn't give many details, but did tell us that the patent was granted for Asetek's thermal interposer liquid cooling system built for use on GPUs.
"As seen in the recently announced AMD Radeon R9 295X2, the graphics cooling market is one that we see as having tremendous growth potential for our desktop business," said André Sloth Eriksen, Founder and CEO of Asetek. "We continue to see increasing interest from GPU and graphics card manufacturers due to increased power use and demands for lower acoustics. Given this interest, it is possible that the GPU cooling business could rival our CPU cooling business in the coming years."
While it is great to see Asetek is working towards making GPU liquid cooling more mainstream, we don't know that many details about this patent so we find it difficult to get excited over this. Instead, find ourselves getting worried. If this is a patent simply on liquid cooling a GPU, or even just liquid cooling a GPU using a closed loop liquid cooler, competing vendors have something to worry about. From the image, it looks like a new concept for a liquid cooling water block, but the exact workings of it are unclear.
Hopefully, this doesn't result in a patent war.
