Cooling systems are one of the most crucial parts of your rig. We often don’t put as much thought into this component as we should, as measuring the increase in performance is harder. Many of us - especially me - get more wrapped up in GPUs and RGB-flashing RAM to do more thought than a cursory search.

A good cooling system can stop your PC from turning into a space heater and keep your CPU safe and cozy so that it can perform at optimal levels. If you prefer all-in-one coolers to fans or water-cooling, you’ll be pleased with these options for an AIO CPU cooler.
