Can you use an air cooler for the 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.

FAQ

Can you use 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.

Final word

The AMD Ryzen 9 7900X offers powerful performance, but this does come with the trade-off of excessive heat production. For optimal cooling, a 360mm liquid cooler is recommended due to its high TDP. 240mm coolers may struggle, while air coolers might throttle during boosts. Water cooling is beneficial for high-end processors like Ryzen 9 but can be pricey.

For the Ryzen 9 7900X, the ASUS ROG RYUJIN III 360 is a top choice. Its large pump and LCD screen contribute to exceptional performance and aesthetics. The Corsair iCUE H150i Elite Capellix is a reliable runner-up. For budget-conscious users, the Phanteks Glacier One 360 offers excellent cooling and an appealing design. Optimal cooling ensures the Ryzen 9 7900X reaches its full potential.
