The best cooler for the AMD Ryzen 9 9900X is the one that fits your budget and build. There are several air and liquid cooling solutions but if you wanted to boost the CPU then we would recommend an AIO if you can afford it. If you think you will stick at stock speeds or even run it in eco mode, you may find a cheap air CPU cooler to be all you need. We tend to recommend 360mm liquid coolers for Ryzen 9 processors but it is important to note they are technically overkill in many scenarios.

Air vs liquid cooling for a Ryzen 9

As mentioned, you don’t need the beefiest cooling solution for one of these, both air and liquid will work just fine. We would advise grabbing an air cooler with a large heat sink and at least 6-8 heat pipes as a minimum. For liquid, any 240mm and above will do the job just fine, which you choose will mostly come down to aesthetics and cost. while we recommend 360mm units below, you can usually pick up the same type in 240mm, 280mm, and sometimes 420mm.

Air coolers are undoubtedly the cheapest solution with minimal noise and almost zero upkeep (fan bearings can sometimes go after many, many years). Liquid coolers, while safe, pose a risk to your system if the pipes or pump become faulty. furthermore, a liquid cooler generally will not outlast an air cooler and may need replacing sooner than you’d like for the price.
