NVR Fan noise

Postby Spikeymikey » Sat Feb 03, 2018 1:39 pm

Am I the only one on here converting my Hik DS7608 NVR fans to super silent 40mm Noctua's?
I've searched the forum but nothing showed up.
My old CNM DVR was fanless and quiet as a mouse but my new Hik NVR sounds like you've left an outside tap running.
I love my Hikvison but can't believe they fit such noisey fans as standard.

I did that to my NVR, but it barely helps since most of the noise is generated when air is flowing through the NVR case venting holes. This can be easily demostrated by removing the case cover, the NVR is almost silent then.

We did buy some silent fans from ebay, did make an improvement!

It depends on the unit and channels in use, for instance, if you have an 8 channel nvr and are only using 4 - clearly, your power demand on the system is half of design - so just unplug one of the fans
