I'm currently building a compact ITX system and want to keep it as quiet as possible. I've heard AIO coolers tend to be quieter compared to air coolers, but since I'm looking at a 120mm AIO, I'm not sure if it will perform as well as larger options like 240mm models. On the other hand, air coolers are generally cheaper. I've mostly used AIOs before, so I could use some input on how a 120mm AIO stacks up against a dual fan air cooler in terms of noise levels.

If you're just building a light gaming setup or a media server, you might not even need a fan cooler; some components can run completely fanless. For something like a Ryzen 5 7600, even a low-powered Wraith Prism should do the job. Just make sure your case has good ventilation!
The cooling performance of a cooler also depends on the power of your CPU. A general rule is that each 120mm can handle around 100W of heat. If your CPU runs cooler at base levels like 65W, you might be fine with a smaller cooler. But if it boosts anywhere near 150W, you might want something more robust than just a 120mm AIO.
It’s not just about the cooler’s type but also the specific models you're considering. While AIOs have a sleek look, they don't necessarily make for quieter builds, especially at 120mm. Fans are the real noise-makers here, and dual fan air coolers generally have more surface area, allowing for quieter operation at lower speeds. I'd say go for the dual air cooler if noise is your priority!
I see what you mean! I'll keep that in mind while I make my final decision.
In terms of noise, dual tower air coolers usually outperform 120mm AIOs. The main reason being surface area; larger air coolers can often run their fans at lower speeds while still keeping things cool. I had an EK 120mm AIO, and honestly, when I compared it with a Thermalright air cooler, the air cooler was much quieter.

Thanks! I'm wrapping up a light gaming machine with the R5 7600, so that sounds promising.
