DeepCool AK400
Community verdict
The DeepCool AK400 is widely praised as an excellent budget air cooler, offering a major reduction in temperatures and noise compared to stock CPU coolers. Owners frequently note its clean aesthetics, pre-applied thermal paste, and simple installation process for mid-range processors. However, several users warn that it struggles and gets loud on higher-end CPUs under heavy all-core workloads, with competing dual-tower coolers often recommended for similar prices.

What people are saying
4 quotesDirect organic buyer opinions about DeepCool AK400, filtered for spam and ads.
Swapping this in basically halved the noise and the temperatures... The heatsink has pre-applied thermal paste.
The Deepcool AK400 has worked perfectly for me so far and I've had no heat issues.
It will work just fine but keep in mind you can get a peerless assassin 120 for the same price and it's a better cooler overall.
It's sufficient. You might get a few % better boosting with a larger cooler and this one will probably get pretty loud under prolonged all-core load.
