The CRYORIG A40 is when you break it down the most affordable of the A-series hybrid liquid coolers. It in fact offers the best overall performance per dollar of the bunch. When it comes to radiators, the 240 mm x 27.5 mm standard design utilized on the A40 delivers performance that matches other units in its class. The difference is the included and optional airflow fan, which allows for cooling of other components around the socket.

In terms of quality, the unit is well built; there were no build quality issues I could make out with the test unit. Add in the MultiSeg mounting hardware and you have a quality product that is easy to install. The warranty is one of the best available if you remember to register your product. So if you want some peace of mind, CRYORIG has you covered with the A40. For those with AMD Ryzen-powered systems, CRYORIG does have AM4 upgrade kits available for free with proof of purchase. Proper support and a good warranty never go out of style.

Of course, if you plan to use system memory with massive heatsinks, the A40 offers exceptional clearance. For mini-ITX users, there is no need to fear as the A40 does not block the expansion slot either. As such, clearance is basically perfect. So if small form factor is your thing and you want an AIO that adds a bit more, the A40 from CRYORIG is a good option. It will not only cool the CPU but also offers additional cooling to the VRM, GPU, and surrounding area in a confined space.

It's not all roses and wine since the unit is loud at 100% PWM, hitting 50 dBA. Generally speaking, the unit will not get that loud most of the time. That said, if you are overclocking, which, let's face it, is kind of the point of having aftermarket cooling of this caliber, you will hear this unit. For some, noise isn't a problem, but for me during my testing, anything over 45 dBA tends to be intrusive. The A40 obviously blows by that.

The hybrid airflow fan is a great idea; however, in my testing, it did not contribute all that much in terms of reported temps. Sure, the VRM section was a few degrees cooler, so it does work, but it didn't really make a difference. On Intel's mainstream offerings, the CPU might get hot, but power draw is still so low that it makes the extra cooling feel a bit gimmicky and unnecessary most of the time. There are, however, instances where it can make a difference. In those situations, such as with SFF and HEDT systems or extreme memory, it likely will have a far greater impact.

Overall, I am impressed by what CRYORIG offers with the A40. The only other thing that springs to mind is the lack of software control, which I myself find unnecessary, though some might miss the feature.

If you are in the market for an all-in-one liquid cooler that does more than cool the CPU while still offering exceptional performance, the CRYORIG A40 is worth considering.
