DeepCool AK400 CPU Air Cooler 220w TDP 6mm x 4 Nickel Plated Copper Heat Pipes CPU Cooler with PWM 120mm FDB Fan 1850RPM for Intel LGA 1700/1200/1151/1150/1155 AMD AM5/AM4, Black

Product Information

The AK400 is a powerful single tower cooler that enables very efficient and quiet cooling thanks to the fan. Arctic’s similarly performing cooler is quieter whilst managing the same thermal performance, but the DeepCool unit manages to outperform the full fan speed SilentiumPC competitors. According to DeepCool, there is also set to be a white version of the cooler available in June 2022. That performance drop-off was minimal, but it does highlight some weaknesses of the included fan – particularly when the Arctic and SilentiumPC competitors have zero-RPM capable PWM fans whereas DeepCool’s is only rated down to 500 RPM.

But the slightly more limited fan speed curve, higher full-speed noise output, and poorer warranty versus the likes of SilentiumPC and Arctic competitors dampen our feelings towards the AK400. Next, you need to use the orange spacers and proper AMD screws to secure the mounting bracket to the backplate. DeepCool’s single 120mm FDB fan running at its 1850 RPM top speed registers 42dBA noise output in our test. Crafted meticulously to offer premium heat dissipation, this cooler elevates your CPU's efficiency by maintaining optimal temperatures under varying workloads. Leave a little wiggle room to then use them to support the bracket while placing the screws and spacers into the top cutouts.DeepCool’s AK400 aims to be a simple, low-cost, 120mm-class CPU cooler that offers value-orientated performance instead of flashy lights. On face value, the cooler is rated for 225 W TDP and the CPU is 105 W TDP so on paper it looks fine to me with headroom in there as well.

With a 50,000-hour rated operational lifespan for the FDB fan, DeepCool looks to be middling for a budget cooler in that number.There is, however, provision for noise reduction, as the fan is mounted to the heatsink with rubber contact dampers. The DeepCool AK400 weighs in at 661g, which is about the average weight for a single tower CPU cooler. And that’s particularly true when factoring in the Arctic cooler's warranty which is vastly superior to the coverage offered by DeepCool. To summarise, we would say that DeepCool’s build quality and ease of installation for the AK400 are positives.
