I have just received an RLN36 and have exactly the same questions. I couldn't find a video or any tech note online. Looks like I'm going to have to contact support too. Crazy!

I am testing a RLN16-410 and a RLN36. The RLN16 has ridiculously loud whiny fan noise and the RLN36 has 2 ridiculously loud whiny fans. The old RLN8-410-E that I'm replacing was completely whisper quiet: what a backwards step in design. My home office is quite small and I keep an eye on all my cameras during the day here and all my camera cables terminate in this room so I have no other placement options for the NVR.

I noticed a YT video which recommended replacing the fan in the RLN16-410 with a quieter Noctua NF-A4x10 FLX. However, there I noticed a significant design flaw with the RLN16-410 - the HD power connector and cables sit right next to the fan and block half the airflow. Worse still, the connector sits directly in line with the CPU heatsink, which blocks direct air flow to it.

The RLN36 has more space and no such design flaw. I'm going to try fitting 2 of the 20mm deep and more efficient Noctua NF-A4x20 FLX in this chassis. According to the specifications, it can be set to 5,000/4,400/3,700 RPM with noise levels of 14.9/12.2/8.5 db(A) respectively. By comparison, the 10mm deep NF-A4x10 FLX has options for 4,500/3,700 RPM for 17.9/12.9 db(A) respectively.

It's crazy that we have to hack the hardware to make the product to the same standard as the old NVR they replaced.

See attached picture for the HD power connector blocking half the fan.

Hope that helps!

I've just bought a Reolink doorbell because the Ring Pro (PoE) version is ridiculously expensive.

I need a few extra chimes. It seems that for over a year they're unavailable, and I noticed that Lorenz locked the discussion about this. Why would the discussion be locked? It seems Reolink doesn't want customers discussing this issue.

I'm regretting this purchase already

Same issue with newly purchased RLC-823A. (10th. September 2022).
