Design and Aesthetics:


The AK400 is a sleek and stylish air cooler that features a clean black top, complemented by a single 120mm black fan, designed for users who appreciate a minimalist aesthetic. The it's single-tower aluminum radiator efficiently dissipates heat, ensuring effective cooling for your CPU. This compact and unassuming cooler not only delivers efficient performance but also seamlessly integrates into a variety of PC builds, making it an ideal choice for those who value both form and function.

Assassin IV

This cooler boasts a clean and modern design that sets it apart from other air CPU coolers available today. The entire cooler is tightly put together, which can make it a bit tricky to figure out how to take it apart into its different parts. The middle fan is hidden seamlessly without any visible gaps around it. It comes in an all-black design with DeepCool's signature textured radiator, adding a stylish and modern touch to any setup.

Install Notes:


This cooler is moderately difficult to install and is more difficult than other DeepCool cooler installations. For AMD CPU's, the mounting setup can be difficult to place due to the mounting bracket doesn't secure through holes, but rather through notches for the AMD setups (This isn't a problem for Intel setups). For this reason, keeping the backplate flush against the motherboard while also keeping the install components in line may prove to be difficult and may require a second pair of hands. This also has a very similar installation to the AG400.

Assassin IV

Installing the Assassin IV is made easier with its smooth setup process. However, because it's small and designed with a lot of details, getting it installed correctly might be a bit tricky if you don't follow the instructions they give you. This cooler uses a bracket that's almost the same as premium coolers and attaches to the motherboard in a way that's like the AK620 model. Figuring out how to put the cooler onto the brackets might be a bit puzzling because its design is so seamless and neat. The top metal mesh that covers the fan sticks on with a magnet, so you can easily access and remove the middle fan during installation. Then, you can attach the cooler to a two-point system and put the middle fan back in place. However, this cooler doesn't put it's fan in the front like most other coolers, so the exposed fan faces the rear. One neat thing is that the fans are already connected, so you only need one plug to turn on both fans and the cooler's LED DeepCool logo. There are additional brackets to potentially add a third fan to the front of the cooler.
