Gaming computers are a complex combination of highly engineered parts. They need to function perfectly so that a competitive gamer can shoot, duck, and move with accuracy. It is common for a computer hardware performance to degrade due to heat generation. We have all seen the major throttling issue with M.2 drives during a heated session. One of the most heated components inside your computer rig is the CPU. Considering that the Ryzen 5000 series is now everywhere over the internet because of its excellent price/performance ratio, we thought we should give our readers a list to decide the best CPU cooler for Ryzen 9 5900X.
Ryzen 9 5900X (Amazon) is an excellent processor for a high-end PC build. It has insane encoding times and top-tier gaming performance. This beast is overkill for gaming, but for content creators and high AI-based applications, 5900x will prove to be the best investment you have made. However, with great power comes great heat. We need CPU temperatures to remain between 50 or 80 °C. Anything beyond 90°C will cause throttling if it is enabled. Otherwise, the system will crash or possibly damage your CPU. To select the best cooler for 5900x, let’s review some of the basic things we need to know so that the importance of the cooler is evident:
Quick Shopping Tips:
Socket Compatibility: First and most important is the socket size of your CPU. If the cooler does not support your CPU socket size, you will have an unusable CPU cooler. Many coolers come with pre-boxed kits that make them suitable for most sockets in the market. The current most used sockets are AM4, LGA1200, and LGA1151. Our list is selecting the best cooler for Ryzen 9 5900X. We already made sure that these coolers are AM4 compatible.
Dimensions: Dimensions might be the most important thing to look for in our list. Selecting the wrong dimensions might end up in a disaster. Motherboards come in different sizes and shapes, so if your air-based cooler is large, it could cover up a DIMM slot or a couple of RAM slots. A higher air-based cooler might interfere with your PC case side panel. For liquid-based coolers, one should carefully match the radiator size with the chassis. Not all chassis support large-size radiators. Be sure to check the above before making a purchase of the best cooler for ryzen 9 5900x.
TDP: Ryzen 9 5900x is an amazingly thermal efficient processor considering the 7nm lithography. AMD states its thermal design power (TDP) as 105W. It means the cooler should be capable of removing 105W of heat from the processor for stable operation. Some test bench enthusiasts have reported that Ryzen 9 5900x reaches a peak of 143W under certain conditions. We will keep the upper value in mind when we select a CPU cooler.
