I recently built a new PC using the NZXT H6 Flow case and I'm noticing that the fans are quite loud. I have three 120mm front intake fans, two 140mm bottom intake fans, and three 120mm exhaust fans connected to a cooler's radiator. There's space for an additional 120mm exhaust fan on the rear panel, but it seems quite perforated already, so I'm not convinced it would help. In the past, I didn't understand how important airflow was and only included one rear exhaust fan, which made my previous machine get dusty quickly. Now, I want to do things right, but I can't find detailed guides on fan setup beyond basic installation and connection.
My CPU temperatures seem okay – averaging around 35-40°C during normal use and peaking at 80°C under heavy load, which I think is acceptable. However, the fan noise is really bothering me, especially during lighter tasks when I'd expect it to be quieter. I have adjusted the fan curves in my BIOS previously but I'm unsure if this is the best practice or if there are other steps I can take to minimize noise. I also suspect there might be an issue with the thermal paste application on my cooler since it was pre-applied, and I'm unsure if a better application could help. Here are my specs: Ryzen 7 9800x3d, Corsair Nautilus 360 cooler, 5070ti, 32GB RAM, and a B850 Tomahawk Max Wi-Fi.

If your GPU is loud, especially under full load, you might want to check the specific model, as some variants have noisier coolers. For your case, ensure that there’s a proper intake and exhaust balance. Sometimes, too many intake fans can cause turbulence, leading to noise issues.
Reapplying thermal paste might help, but if the cooler is making good contact, it should suffice. Focus on balancing your airflow – you want to ensure that air is being pulled in and pushed out without restriction or overlaps to maintain cooling efficiency.
Adjusting the fan curves in the BIOS is definitely a solid practice! You can also explore using a software tool like FanControl, which allows for finer control of your fan profiles directly from Windows. This could help you find a balance between cooling performance and noise level.
I was worried that if I set a less aggressive curve, it would cause higher temperatures. Do you think that’s true, especially since my CPU is already getting warm?
I have the ASUS TUF 5070ti, which has three fans. What do you mean by avoiding 'double intake' on both sides of the case?
