I'm building a high-end white-and-blue PC mainly for 4K video editing and music recording. I've researched the parts for a while, but I'm not sure how quiet the system will actually be, especially under sustained workloads. The planned parts are an Intel Core Ultra 9 285K, Thermalright Phantom Spirit 120 air cooler, Gigabyte AERO OC RTX 5070 12GB, 32GB of DDR5-6000 memory, a Gigabyte Z890 AORUS PRO ICE motherboard, a 2TB Samsung 990 EVO Plus NVMe SSD, an 850W Platinum power supply, and either a be quiet! Dark Base Pro 901 or Dark Base 701 case. I'm not too concerned about the budget, but I would like the system to stay as quiet as possible while matching the white-and-blue theme. How quiet should I expect it to be in normal use and during editing or recording?

A 360mm AIO could keep the processor cooler under sustained workloads, which may let its fans run more slowly. However, an AIO is not automatically quieter: the pump creates a constant sound, and radiator fans can become noticeable under load. A large air cooler with a well-tuned fan curve may be quieter during light use.
The Phantom Spirit is a capable cooler, and silence will depend more on fan curves, case airflow, and workload than on the cooler type alone. You can configure the CPU and case fans to stay very quiet at low temperatures, but expect some noise when the processor and graphics card are rendering or encoding. The Dark Base cases should help with acoustics, although good airflow is still important.
It may be worth comparing the Core Ultra 9 285K with the 270K Plus. The latter can perform similarly in many workloads and may even be faster in some, while running at a lower cost. That said, if your bundle includes the white motherboard, memory, and processor for significantly less money, keeping the 285K is perfectly reasonable.
The bundle is about $250 cheaper than buying the Core Ultra 7 and the other parts separately, so the 285K package seems like the better value in this case.
I’ve found that a quality air cooler can be quieter than an AIO at full speed because the AIO pump produces noise by itself. I wouldn’t switch to liquid cooling solely for lower noise unless you also prefer the appearance or need the extra thermal capacity.
