Just as an update to this OLD post. Please see my mod earlier in this discussion. My unit is in my garage. It has been working without incident since installation. No overheating, no issues. I'm posting this because outside temperatures have been 95-100 degrees, and my garage has been around...

Replying to myself... because I couldn't resist, I plugged 14 fans into a spreadsheet and calculated CFM per dBA. They were all in a pretty tight range of 2.55 to 2.86 dBA/CFM. So there is a fairly direct relationship between noise and cooling ability. Basically, to move 10 CFM of air, you are...

>MF40201V2-1000U-AA99 says it moves 13.08 cubic meters per hour with 0.17 inches H2O pressure from 6,000 RPM producing 21 dBA of noise >Stock fan moves 15.78 cubic meters per hour with 0.354 inches H2O pressure from 8,200 RPM producing 30.5 dBA of noise >Noctua moves 9.4 cubic meters per hours...

I have a Dahua 8 camera Power-Over-Ethernet NVR (NVR 4208-8P-4K-S2). I suffered from the same fan noise issue here as everyone else. To echo the comments and provide some clarifications and precautions, at least on this NVR unit. A) This NVR has two fans. The first is commonly called the 'case'...
