Best AIO cooler for Corsair 275R Airflow 2021

I'm a fan of the Corsair 275R Airflow and believe it offers excellent value for those wanting to build a PC on a tighter budget. Even the best PC cases require good cooling to keep components running within optimal temperature ranges, and the 275R Airflow is no exception. Here are our recommendations for best AIO cooler for the Corsair 275R Airflow.
Best overall
We're big fans of NZXT's Kraken series of AIO coolers. The Kraken Z63 is a 280mm AIO with a fancy smart water block. There's a 2.36-inch display that can be controlled through the company's CAM software to display important information related to temperatures or even your own images.
Corsair Hydro iCUE H100i Elite 280mm
Same brand
The Corsair Hydro Series is a range of strong AIO liquid coolers that comes in a clean white (or black) look. If you're someone who wants a two-toned look in their case and the benefits of an easy-to-install cooler, this is it. The fans and water block are RGB friendly, which is great since the Airflow case doesn't come with any RGB lighting.
Best value
be quiet! makes some of the best fans on the market for PC cooling so it only makes sense that the company should know a thing or two about water cooling. The PURE LOOP series offers excellent value for keeping the CPU in check under load. It's a 280mm AIO without any RGB lighting but does come with a detached pump for less vibration and noise.
Best performance
Think of the Kraken Z73 as the same AIO as our top recommendation, but with three 120mm fans instead of two larger 140mm blowers. The radiator has also been extended from 280mm to 360mm. This will still fit just fine inside the Corsair 275R Airflow and offer more thermal capacity for overclocking.

The Corsair 275R Airflow is a great budget case that can support AIO coolers with radiators up to 360mm in length. This opens up a large collection of supported coolers, some of which have been highlighted in this collection. We'd recommend at least 240mm as a sweet spot for most processors.
NZXT's Kraken Z63 is a beast of a cooler. This thing can handle an overclocked AMD Ryzen 9 5950X without issue. It's available in black or white, has a small display to show temperatures or cool GIFs, and has two very good static pressure-optimized fans.
The rest of our recommendations are great for keeping with the same Corsair brand, saving some money in the process, or splashing out and getting the best thermal capacity for overclocking.
