In this review, we strapped the DeepCool AK400 to our test bench to see how it performed against other air coolers that we’ve tested. It’s a budget-oriented 4 heatpipe tower cooler with a 120mm fan that looks different due to the top cover that DeepCool adorned it with for $34.99 MSRP. So, let’s recap the performance below and see how the DeepCool AK400 stood up!

Summary of Temperatures

DeepCool AK400 With AMD Ryzen 7 2700X

At stock speeds, the DeepCool AK400 turned in relatively solid numbers for a small, four heatpipe tower cooler with a single 120mm fan. With fans turned to 11, it maintained 58.75 degrees Celsius. It did a fairly good job of keeping the cool as the fan speeds dropped to 1000RPM during testing, though, at 600RPM it was done trying.

When overclocking, the best we can say is that the DeepCool AK400 survived testing its higher fan speeds, but turned in less than ideal temperatures. Ultimately, we were able to keep our AMD Ryzen 7 2700X in stable at 4.1GHz at the Max fan setting and 1500 RPM setting and no lower.

Summary of Sound Levels

DeepCool AK400 Sound Levels with AMD Ryzen 7 2700X

At its highest fan speed settings, the DeepCool AK400 was barely audible over the ambient room sound levels, with our decibel meter rating it at 46.4 dB(A). As we slowed the fan speeds, it disappeared into the ambient noise of the room, generally quieter than the competition that we reviewed it against.

Final Points

The DeepCool AK400 is priced as a budget cooler at its MSRP of $34.99, which is a solid $20 under the current street price of the SilverStone AR-01 V3 and about $10 under the current street price of Cooler Master’s Hyper 212.

From a performance perspective, it outcooled the SilverStone AR-01 V3 but was warmer than the Cooler Master Hyper 212 EVO. From a sound perspective, it hushed far better than the other comparison coolers.

When you consider the overall performance from a cooling and sound perspective and factor in its price, the DeepCool AK400 is a beast when considering the overall value even if it is not the absolute best performer and not a cooler you’d want to overclock with.  

If you’re in the market for an inexpensive, aesthetic, and quiet cooler that will get the job done at stock speeds, look no further than the DeepCool AK400. Check out our pricing widget above to see what it is going for today.
