A40 is not only a German Autobahn but also a so called all-in-one watercooler by manufacturer Cryorig. These kind of coolers are a real trend for CPU cooling for a few years now. It is promised a water cooling without the often maintenance and installation with a cheaper purchase price. Cryorig is known as an innovative manufacturer of CPU coolers and has detected as a weak point of such systems that compared with air cooling systems often the surrounding components not be cooled. That’s why Cryorig has decided to integrate an additional fan above the CPU for their Cryorig A40 all-in one cooler. This also applies to the big brother Cryorig A80, which is available with a larger radiator. We have checked if and how that affects in practice, in the following Cryorig AIO test at OCinside.
