Best 240mm AIO Coolers for Gaming & Work PC in 2024

The most commonly used AIO liquid CPU cooler size is the 240mm one because it can fit in most modern-day mid-tower cases and provides a good amount of performance. A 240mm AIO is undoubtedly better than the 120mm AIO, and some of the best 240mm AIOs can deliver performance almost equal to that of a decent 280mm AIO. However, a 240mm AIO can be beaten by a good CPU Air cooler, especially one with a dual tower design or with a larger heatsink and dual fans.

A 240mm AIO Liquid CPU cooler consists of a 240mm radiator that is made of aluminum (for most AIOs) and two 120mm fans on it. It is not as intrusive as the 280mm or 360mm AIOs that are pretty bulky and require a large enough PC case to fit. A 240mm AIO is generally preferred for a mid to high-range processor but should be avoided for the top-of-the-line flagship processors with much higher TDP. Moreover, a 240mm AIO cooler is not recommended for high-end overclocking, but you can perform a moderate amount of overclocking of a fast mainstream or mid-range processor.

There are many 240mm AIOs available from different brands, but they differ in performance by quite a significant margin. Some of them deliver better cooling performance, some are quieter in operation, while some sports fancy RGB lighting and are better in the looks department. So, to help you make a wise decision, here I am going to list down the best 240mm AIOs that you can get for your Intel or AMD processor.
