Just got a Hikvision DS-7616NI-K2 NVR and it lives in my home theater cabinet but the fan was WAY WAY too loud! I have great ventilation in there so it would have been nice if the fan was thermally controlled but nope, runs full tilt all the time :(

With all that empty space I figured I could fit a better fan in there and remove the stock one!!! :)

The offending fan:

I bought a DeepCool UF120 fan. It's got a rubber frame and comes with rubber "mounts" for the fan too for zero vibration noise.

I started by finding a place inside the NVR where the fan would fit with two hard drives still in there! Was very easy. Then, with the fan and everything except the hard drive(s) in the NVR I drilled mounting holes through the bottom of the case (through the existing ones in the fan). Then I screwed the fan to the BOTTOM of the NVR (i.e. on the outside) and traced the inside of the fan:

Then I removed the fan and motherboard from the unit and cut the shape out on my jigsaw. Worked flawless.

I needed a way to connect the fan to some power. These fans run awesome at 5v (silent but stills pushes a lot of air!) so I stripped the red hard drive wire (+5v) and one of the black ground wires (if you wanted to run the fan at full speed you could tap the yellow wire instead of the red) then cut off one of the molex to fan adapters that came with the fan:

I soldered the wires together, electrical taped it up, done and clean!

I re-installed the hard drive and motherboard and installed the fan using the rubber anti-vibration mounts it came with, flawless:

Still tons of room above the fan for it to breathe (between the top of the fan and the top cover case when installed):

Not much room under the NVR though, but if can't exhaust much air I could install some rubber feet on the metal feet of the NVR for a bit of extra height.

I turned off hard drive sleep in the NVR settings, told it to record 24/7, so will let it heat soak for a day or two then check the hard drive temperature. I just installed it right now, but it was still warm from the 48c it was running at before, so it's reading 37c degrees just after booting up for the first time, lets see where it goes from here.

Totally silent, lots of flow, exactly what I wanted.

After running for 24 hours the hard drive stabilized at an amazing 29c temp!!! INSANE! If I'm playing a 4k movie on my home theater stuff it goes up to about 31c because of the temp rise in the home theater cabinet but still super acceptable for being completely silent :)

Now I'm just waiting for my Hikvision 4k DS-2CD2385FWD-I cameras to show up and then I'm all set :)

Nice fan setup. Saw you had a news feed in the camera 1 slot in your picture. Can you please explain how you were able to do this? Thanks

Thanks for asking! I've had quite a few questions about that :)

That video/audio feed you see for "camera 1" is coming from a satellite receiver (think Dish Network, Echostar, etc.). Any device that outputs HDMI is fine (satellite receiver, cable TV box, etc.).

Here are the steps:

First thing you need to do is run an HDMI cable from your source to a HDMI signal decrypter (if it's coming from a Cable TV or satellite box, etc.): HDMI 1 In 2 Out Splitter Amplifier Duplicator Full 1080P 3D V1.4 DVD HDTV USB | eBay

Then plug one of of the hdmi outputs on that decrypter/splitter into this Onvif HDMI to Network encoder: H.264 HDMI Video Encoder via HTTP RTSP RTMP UDP ONVIF to IPTV Stream Broadcast | eBay

You can connect your TV to the other output on the decrypter/splitter if you want (and it'll display the original HDMI stream).

Plug the encoder into your network (DHCP is fine) then run a scan for new cameras in your NVR and it will pick up that encoder as an "onvif camera" and display it perfectly (with audio too!). I use it for watching the news when I'm at work (with ivms 4500 app) :)

Set the output frame rate to 30fps in the encoder (it defaults to 60), otherwise the NVR might just show a black picture.

If you have problems with the HDMI signal being unstable (pixelation, green squares, etc.) use shorter (or higher quality) cables between the source and the decrypter/splitter and between the decrypter/splitter and the encoder. When I first hooked it up I had $1 china 6ft HDMI cables for each (so 12ft end to end total) and was having lots of issues. I upgraded to nice quality 1ft cables and zero issues after that.

Thanks for the info. Was hoping you found some trick to use a website. I use a similar device for other kinds of feeds with BNC instead of hdmi like yours.

There are tons of pirated RTSP streams online so I imagine you could use one of those as an RTSP camera source. I tried a few but the audio format was NEVER in a compatible format for the NVR to accept and trying to feed it through ffmpeg to transcode the audio always messed up the audio/video sync (would drift out after a while) so I gave up on trying to use pirated streams and just tried using my satellite receiver. I didn't realize all HDMI streams were encrypted (from cable TV boxes, satellite receivers, etc.) but luckily there were simple and dirt cheap unecrypter devices for it.

Is there a particular news channel you're looking for?

Am I the Only user that does not see the images in this post?
 
I know it's been a while you posted this thread. Would you be able to tell me why did you tap into the hard drive wires instead of connecting it to the 2 pin connector for the original fan?
Is it because supplied voltage only 12v from the 2 pin connector?
Thanks.

I wanted to run the fan at 5 volts instead of 12 and even on a cold boot the 2 pin connector was putting out 12v (no PWM or anything, full speed 24/7).

Still running absolutely perfectly!

For what it's worth, I have a new 7608-I model that I installed about 10 days ago. Build date is June of 2018. The fan is nearly silent - you have to tilt your head to the side and really listen in order to hear it from just 3 feet away. I wonder if a new model of fan is being used?
 
Hi guys, here my 2cents.
As many of you I had trouble with the extremely noisy fan mounted on my DS-7608NXI-I2/4S (single, Nidec 40mm, fan) always spinning at the max speed.
Changed with a Noctua NF-A4X10 FLX which is definitely spinning much slower (5000 RPM) and the noise dropped significantly now.

I did not find an increasing noise due to the airflow through the cabinet holes.
The noise went from 48 db.A to around 32 db.A, measured outside the closet which is hosting the NVR.
Temperature at disk raised from 23°C to around 34°C but still pretty far away from the 45/50°C Threshold.

I hope this may help.
Cheers
 
HI All,
I just watched a video of someone with a HikVision NVR who replaced the fan in the power supply to reduce the noise as well. He ended up using the on board 2 pin connector to connect to a 3 pin adapter. The 3 pin adapter was then connected to a Noctua 20 x 40mm fan. I think I would like to find a solution to replace both of the fans , i.e. power supply and case fans.

Does anyone know where to find a 2 pin to a Y splitter 3 pin to support the power of two fans?
