 With the right CPU cooling, your Ryzen 5 5600x can run at full potential and give you years of reliable service. These coolers have a lot of features that will be appealing to both gamers and workaholics alike, including high-performance cooling or quiet operation, depending on your needs. For more information about any one of these products in particular, please see our individual reviews above. We hope this list has proven helpful in narrowing down which product may best suit your needs!


Air coolers use a traditional metal heatsink over the CPU. This transfers heat from the processor to fins above it, where fans blow air across them and keep the system cool.

Liquid coolers work similarly but instead of a heatsink, they use a small radiator or at times, a series of radiators connected together with tubing that leads to an external pump and reservoir combination. The liquid is then cooled through this setup using either a 120mm fan or a 240mm fan. Decorative lighting is also included in most cases. 

This is a question that will depend on your requirements. Air coolers are usually smaller but can be loud if not adequately controlled. Liquid coolers tend to be larger and more expensive, but they run quieter and need little to no maintenance at all. In short, air coolers are best suited for those who want a flashy build with high-performance cooling while liquid coolers are better suited to those who want a quiet system or have extra room inside their case for a radiator.

The power of a PC is measured in Watts. So higher the temperature, the more heat energy your system will need to remove. Because remaining too hot for extended periods of time can cause damage or shorten the life span of your system. Optimally, your CPU should have temps around 60-80ºC at full load. If you’re getting more than that, it might be time for an upgrade!
