Keeping your CPU cool is one of the more consequential decisions in any build. The choice broadly comes down to air or liquid: a good tower cooler with a 120mm or 140mm fan can handle most mainstream processors quietly and reliably, while all-in-one liquid coolers with 240mm, 280mm, or 360mm radiators offer more headroom for high-TDP chips and are worth considering if you're pushing a flagship CPU under sustained loads. Key specs to pay attention to include TDP rating, socket compatibility (particularly with AMD AM5 and Intel LGA1700/1851), fan static pressure, and noise levels measured in dBA.

We compare coolers from established names like be quiet!, Arctic, DeepCool, and Noctua alongside the more feature-laden offerings from ASUS, Corsair, LIAN LI, and NZXT. Prices span a wide range, from budget-friendly air coolers to premium AIOs with LCD displays and addressable RGB pump heads.

One current trend worth noting is the growing popularity of LCD-screen AIOs, which let you display temperatures, custom images, or system stats on the pump head. They look impressive, but the underlying cooling performance is what matters most, so always check the thermal benchmarks before the aesthetics.
