Know before you buy
The AK400 features a standard tower design that fits most mid-tower cases. It is 155mm tall, so you should check your case's maximum CPU cooler clearance specification before purchasing.
Yes, it supports a wide range of modern sockets, including Intel LGA1700, 1200, and 115x, as well as AMD AM5 and AM4 platforms.
The fan uses a Fluid Dynamic Bearing and is rated for a maximum noise level of 29 dB(A). It remains very quiet during normal operation and only becomes audible when the system is under a heavy thermal load.
The cooler uses a straightforward five-step installation process with an all-metal mounting bracket. It is designed to be secure and intuitive, even if you have limited experience building PCs.
With a 220W TDP rating, the AK400 is optimized for mainstream processors. While it handles standard gaming and productivity workloads with ease, it is not intended for extreme overclocking or high-wattage enthusiast-grade CPUs.
