Antec A40 Pro & C400 Air Cooler Review

Rating: 8.0.

The budget air cooling market is fiercely competitive, and it is this segment that Antec is targeting with its A40 Pro and C400 coolers. Oddly, the A40 Pro is the cheaper (and smaller) of the two despite its ‘Pro’ moniker, coming in at £21.95, while its bigger brother costs £30.95. Can they do enough to stand out in this market?

Over the last few years we have seen a number of challenges to the Cooler Master Hyper 212 EVO’s status as ‘budget cooling king’ and currently we recommend the Cryorig H7 if you want an air cooler under £35. Antec will be hoping that its A40 Pro and C400 coolers can do enough to win that title outright – so let’s dive in to the review and see how things go.

    Master air pro 4 is a heatsink with 12cm fan. While antec a40 pro is only equipped with a 9cm fan. How can the performance be so identical?

    Many more variables to this, fin density and length for example, also at 1.3V you don’t actually max out the heat that 4 heatpipes can carry so there is that…
