A liquid CPU cooler, or all-in-one (AIO), moves heat away from a hot processor more effectively than most air coolers while looking clean and freeing space around the socket. For high-core-count and overclocked CPUs, a good AIO keeps temperatures and noise in check. The choices come down to radiator size, noise, and whether you want RGB or an LCD display. This guide compares the best liquid CPU coolers available now.

Frequently Asked Questions
Do I need a liquid cooler?
For hot, high-core-count, or overclocked CPUs, an AIO keeps temperatures and noise lower. Many mainstream chips run fine on a good air cooler.
240mm or 360mm AIO?
360mm offers more cooling headroom for hot CPUs; 240mm suits smaller cases and cooler processors. Match the size to your case and chip.
Will it fit my case?
Check your case’s radiator support and clearance. Thick radiators like the ARCTIC’s need extra space.
