Performance
Stock clocks shouldn’t be hard for any CPU cooler these days, but the A40 made fairly easy work of them anyway. The Ultimate managed just +24c above ambient, which is just +1c more than the much larger 280mm radiator of the Cryorig A80.
Pushing the temperatures up while overclocking proved easy for the A40 Ultimate at just +34c and amazingly the same as the Cryorig A80, although that’s a 280mm thin radiator, this is a 240mm thick radiator.
The A40 managed a steady 40dBa throughout stock testing, which is pretty quiet and unlikely to be of concern, especially in a chassis and not on an open air test bench like the one we use.
Amazingly, the A40 was still on par with the A80, and by the tiniest margin, a little bit louder, but you wouldn’t notice it was without the use of a decibel meter as they’re both pretty quiet overall. This is great, as it means you could comfortably up the fan RPM for better cooling performance without much sacrifice to acoustics.
