Re: RLN36 Fan Noise
I'm now running my RNL36 for more than a year without the fans. They were removed on day 3. It runs 24/7. It is set to record on alarm only and fitted with an SSD. I placed some 20mm high wood under it to increase the passive airflow area, and placed a 20x20x20mm aluminium U section the width of the casing on the processor as heat sink. Measured with a Fluke62 the temperature stays within 5C of ambient. For me the led lights could be less bright. I use the alarm output anyways. As it is all low voltage inside, and the casing is fairly empty, there are many ways to increase passive airflow even more
