My Ryzen 7 7700X is currently cooled by a DeepCool AK620 in a Cougar Duoface Pro RGB case. The system also has an RTX 4070, an MSI B650 motherboard, and 32GB of DDR5 memory, and I mainly game at 1440p. The CPU is configured with an 80W power limit and a negative-20 curve, typically reaching about 65–75°C while gaming. The original AK620 fans eventually developed an irritating humming or resonance noise, so I replaced them with Arctic P12 Pro fans. Unfortunately, one of those developed a noticeable rustling or scratching sound and was returned under warranty. Its replacement has now started making a similar noise as well. At this point, I'm unsure whether I've simply had bad luck with fans or whether I should replace the entire cooler. Would you keep the AK620 and buy another pair of fans? If so, which models offer good airflow, low noise, and dependable bearings? Or would an AIO liquid cooler make more sense? I'm not trying to achieve the lowest possible temperatures—reliability and quiet operation matter more to me, even if the CPU runs a little warmer. Is the AK620 still more than sufficient for this processor?

I’d keep the AK620 and replace the fans rather than moving to an AIO. Your gaming temperatures are already perfectly reasonable, so there isn’t really a cooling problem that liquid cooling would solve. An AIO adds a pump and more potential failure points, while a good air cooler is simpler and generally easier to maintain. Since your main priorities are reliability and low noise, sticking with the tower cooler makes more sense.
You could also use one high-quality fan in the center of the AK620 instead of immediately buying two. A Noctua NF-A12x25 should provide plenty of airflow for a 7700X, operate quietly, and have a strong reputation for long-term reliability. With your current power limit and gaming temperatures, a single premium fan may be all the cooler needs.
That sounds appealing, though my build is white, so I’d prefer a reliable white or light-colored fan if possible.
That’s what I’m leaning toward, although I’m frustrated that the replacement P12 Pro has also started making a rustling noise. I may try a different fan model next time.
