Buying Guide: The Specs That Matter
Air vs Liquid
From a data standpoint, premium dual-tower air coolers rival 240mm AIOs and need no pump; liquid AIOs handle the hottest chips and free up clearance.
Socket and Clearance
Looking at the numbers, verify socket support (AM5, LGA1851) and measure RAM and case clearance — tall air coolers can block memory or side panels.
Radiator Size and Noise
On specs, 240-360mm radiators tame high-core CPUs; larger sizes run cooler and quieter at the same load.
