Keeping your Intel Core i7-12700K processor cool is essential for optimal performance and longevity.
The 12700K is a powerful CPU that generates significant heat during intensive tasks like gaming or video editing. A good cooling solution prevents thermal throttling, which can slow down your system when temperatures rise too high.
Air coolers and liquid coolers are the two main options for the 12700K.
Air coolers use metal fins and heat pipes to draw heat away from the CPU, while liquid coolers use a pump and radiator system for more efficient cooling. We’ve found that high-end air coolers can match entry-level liquid coolers in performance, but the best liquid coolers typically offer superior cooling for this powerful processor.
When choosing a cooler for your 12700K, pay attention to thermal design power (TDP) ratings, compatibility with LGA 1700 socket, and clearance for RAM and case.
Noise levels are also important if you prefer a quiet system. After testing numerous coolers with the 12700K under heavy loads, we found the Arctic Liquid Freezer II 360mm to offer the best balance of cooling performance and value.
