I recently got a pre-built gaming PC with a CyberpowerPC setup (7800x3D CPU, 9070XT GPU, and Phanteks Evolv S2 case) and overall, I'm pleased with its performance. However, I've noticed that the AIO pump is quite buzzy, especially when my PC is on quiet mode, making it a bit more noticeable against the near-silent operation of the rest of the system. I know the AIO cooler is probably not the best, so I'm considering an upgrade. I'm torn between getting a better AIO or switching to an air cooler for improved silence. My budget is under $150 for either option. Any suggestions?

Definitely consider a tower cooler, especially if silence is your goal. For CPUs like the 7800x3D, which isn't particularly hot, tower coolers can really shine. A good model will keep the CPU cool and quiet. You can grab a solid air cooler for under $60, and I've seen deals on the Phantom Spirit recently.
If you're really aiming for the quietest setup, I'd say go with an air cooler. They don’t have a pump, so they're typically much quieter when the PC is idle, which sounds like your priority. The 7800x3D doesn’t produce a ton of heat, making dual tower coolers like the Thermalright Phantom Spirit a great choice. They operate quietly both at idle and under load.
If pump noise is concerning to you, I’d lean towards an air cooler. I used AIOs before and always found the pump noise a bit annoying. A big air cooler with low RPM fans would likely serve you well. I personally advocate for the Phantom Spirit. It’s a crowd favorite for a reason!
Have you checked your BIOS settings? Sometimes the pump speed can be set to follow the CPU temp, causing it to be louder. Setting it to a fixed speed might help reduce the noise. However, if the pump noise is just unbearable, switching to an air cooler might be the best bet.
Even a low-profile cooler like the Thermalright APX 120x67 can manage the cooling for a 7800x3D really quietly. It’s all about airflow and fan speed. Aim for a fan curve that keeps speeds under 80% for quieter operation. Just make sure it fits in your case!
