While the AMD Ryzen 9 7900X isn’t the flagship CPU, it is an absolute beast.

For those that aren’t after the top-end, enthusiast-level performance, a 7900X is going to be all you need, however, a suitable cooling solution is essential.

Just like the flagship, the best CPU cooler for the Ryzen 9 7900X is going to be an AIO 360mm liquid cooler.

So let’s celebrate your recent Ryzen 7000 purchase and give it all the cool water it requires.

Best cooler for 7900X: First look


Can you use an air cooler for Ryzen 9 7900X?

AMD’s Ryzen 9 processors from the 7000 series feature a default TDP of 170W.

This would lead many to believe that a beefy air cooler might cut it, however, some of the best air coolers can only handle around 205 TDP.

This means that when the Ryzen 9 processors are in boost, they may throttle with some air coolers and even small AIO coolers, so a 360mm liquid cooler is our top recommendation.

What about 240mm coolers for AMD Ryzen 9 7900X?

While you may get away with a high-end 280mm AIO, we feel that 240mm could struggle.

With less surface area on the radiator and few fans pushing that hot air away, you could experience performance issues.

This, of course, depends on what you are doing with your CPU but to stay on the safe side, we think you should aim for a 360mm AIO for the Ryzen 9 7900X.

240mm coolers will be better suited for the Ryzen 5 and Ryzen 7 SKUs.

Should I water cool my AMD Ryzen 9 7900X CPU?

High-end processors like the Ryzen 9 SKUs in AMD’s 7000 series would benefit from water cooling but unless you have a huge budget or specific requirements, you may want to stick to an AIO.

The performance of water cooling on a commercial scale is unbeatable but it comes with a cost.
