i recently purchased a DHI-NVR4232-16P-4KS2 and found the chassis and PSU 40mm fans excessively noisy, and unbearable to tolerate in my work/study room.
I replaced the chassis fan with Noctua NF-A4x10 FLX 4500RPM 40mm
and replaced the PSU fan with the Noctua NF-A4x20 40mm FLX 5000RPM
now it's all whisper quiet...how it should be....
why Dahua can't choose a better / quieter fan ???
