Introduction to the Fan in Reolink NVRs

All Reolink NVR system except for the RLN8-410-E NVR system comes with a Fan, which is used for heat dissipation. If you want to replace the fan to solve some problems, please make sure that you make it carefully or refer to professional knowledge in case of damage to the NVR system.

Applies to: Reolink NVRs 

Normally, the sound of the fan is under the normal sound range.  If your NVR model is the old version and comes with a noisy fan, it's suggested to put the NVR system in the place with fewer activities, especially far from your bedroom. 

Considering the noise caused by the fan, Reolink replaced the fan of the new model 8-channel NVR system RLN8-410 with the heat sink, which greatly reduced the noise from the working fan, and Reolink will consider replacing the fan for all models NVR systems with the heat sink step by step in the future soon. 

If the sound is still very loud and noisy, please use the Decibel Tester to test the sound range and report to Reolink support.
