Top 8 Best 120mm AIO CPU Coolers in 2021 – NZXT, EVGA, Corsair, Cooler Master

By | April 29, 2021

AIO Cooler come in varying sizes in terms of the radiator length, and 120mm is the smallest size.

The radiator typically fits a 120mm fan and provides moderate levels of cooling.

Liquid cooling offers lower temperatures, quieter fans, and eye-catching aesthetics. AIO stands for all in one, particularly referring to liquid CPU coolers. AIO coolers are a combination of a radiator, water block, tubes, fittings, fans, and pumps.

Compared to your regular air coolers, AIO coolers contain a special type of liquid. It's usually a combination of distilled water and a thermally conductive fluid enclosed in a loop through a tubing system.

Compared to the more popular 240mm size aio coolers , the 120mm coolers are less powerful in terms of cooling and can be usually easily outperformed by similarly sized air coolers.

Remember that the cooling capacity is directly proportional to the radiator size. More-over due to smaller radiators in 120mm aio coolers, the fan will have to spin faster to dissipate heat resulting in more noise that might not be very comfortable for everyone.

Ideally 120mm aio coolers should be used if you are using a low tdp/thermal cpu and you want a cool looking aio cooler with RGB effects in a compact build.
Otherwise it is better to go for an air cooler or a 240mm cooler.

If you plan to use a 8 core or more intel/amd processor or do overclocking of any kind of any other cpu intensive work like video editing, then 120mm aio coolers are not recommended. Get a 360mm aio instead.

With famous tech brands expanding and new brands entering, AIO coolers are in a very saturated market today.
