Accessories

The three additional modules come in typical Corsair packaging, but with clear differences between show and function. The LCD screen and the VRM fan are packed in striking yellow boxes that immediately look like Corsair and signal that these are premium accessories as soon as they are unpacked. Inside, everything is neatly inserted, firmly fixed and without superfluous plastic padding. You open the lid and get a direct view of the respective module without having to dig through additional layers.

The Pump Cap stands out visually and comes in a plain brown box with minimalist printing. This makes a much more unagitated impression, but still has a clean structure. The module lies securely in the box and is protected by a clear transparent film; the packaging clearly focuses on function rather than color. Corsair saves itself the marketing fireworks here and delivers a sober but tidy package.

All three boxes contain the essentials, neatly sorted and without chaos. Nothing rattles, nothing flies around, and the modules themselves are positioned in such a way that they can be easily removed. Typical Corsair: lots of structure, little risk and a clear focus on ensuring that the modules look as they should after shipping.

The optionally available iCUE LINK VRM Fan is a small but very useful additional module. It is connected directly to the pump block and blows air directly over the surrounding mainboard components. With modern CPUs, especially on AM5, this can certainly add a few degrees to the VRMs and the socket area. The fan is compact, easy to install and fits seamlessly into the link system. Acoustically, it remains inconspicuous as long as it is not deliberately forced to maximum speed.

The iCUE LINK LCD screen is the visual gimmick for anyone who wants more than just RGB. It replaces the standard pump cover and displays temperature values, animated graphics or your own content. The integration into the Link system is clean, the display is bright and clear and the readability is good. Technically, the display does not add any value to the cooling performance, but for users who like to see system values directly on the AiO or want to round off their system visually, it is a high-quality and well-made upgrade.

The pump cap serves as an alternative to the LCD module and is a simpler addition to the pump cover. It offers a slightly different design, a cleaner look and fits well into builds that focus less on show and more on a clear line. This module is also simply plugged on and integrated via the link system. Nothing changes functionally, the pump remains identical, but the overall visual appearance can be adapted without much effort.
