My Pop Mini Silent was nearly perfect when it housed a Ryzen 7500F and RTX 4070 Super, but it now contains a Core i7-14700K and RTX 5080. The system is functional, but the fans need to run at high RPM, and removing the side panel noticeably improves airflow and reduces noise. Once the fans get loud enough, the case's sound-dampening panels do not help much.
Noise is a major concern for me, so the case is fitted entirely with Noctua fans. I recently tried a HAF II 500, but returned it because its included ball-bearing fans produced an audible grinding noise. They were quiet at very low speed but barely moved air, and at useful speeds the bearing noise was distracting. Replacing them with Noctua fans was not practical because the case relies on unusual 220 mm front and 180 mm rear fan mounts, with no suitable mounting holes for common 140 mm or 200 mm fans.
I'm looking for a genuinely quiet case with strong airflow, preferably in a compact mATX size. Cases I'm considering include the NZXT H3 Flow, darkFlash WD200, and Lancool 207. I'd likely install Noctua fans in any of them. For a larger case, I'm also considering the ASUS ProArt PA401 and HAVN BF360, since their included fans appear to use better-quality FDB bearings and LCP blades.
Has anyone compared these cases, particularly for keeping a 14700K and RTX 5080 quiet without resorting to very high fan speeds?

The HAF II’s bearing noise and its airflow performance are separate issues. At minimum speed the fans were mechanically quiet but ineffective; at medium speed they moved air but exposed the bearing noise; and at high speed the airflow became louder than the bearing. That makes them a poor match for someone who is particularly sensitive to tonal or grinding noises.
If you choose a larger case, the ProArt PA401 or HAVN BF360 may be safer options because their included fans use more suitable bearing and blade designs. Still, I’d verify that the fans are genuinely quiet in person or plan to replace them, since review measurements often do not capture irritating mechanical sounds.
The Lancool 207 seems worth serious consideration. It is close to the Pop Mini in overall footprint but has a much less restrictive airflow layout, and it performs well in noise-normalized testing. Swapping its fans for Noctuas should give you a better chance of running low RPM without the side panel removed.
The H3 Flow could also work, but I’d check the exact GPU clearance, front-fan support, and intake restriction before buying. The main goal is to avoid another case that depends on proprietary large fans you cannot replace.
Sound-dampening panels mainly reduce higher-frequency fan noise. Once the fans are moving a lot of air—especially above roughly 1,500 RPM—the airflow itself becomes the dominant sound, and restricting the intake makes things worse. The side panel helping is a strong sign that the front intake is too restrictive.
For this hardware, I’d prioritize an open front, several large low-RPM intake fans, and a GPU-aware fan curve over acoustic foam. A 14700K and RTX 5080 produce a lot of heat, so a compact case may not remain quiet unless the power limits and fan curves are tuned carefully.
