- Walk-through on how to swap your standard jet engine fan for a silent one. This is for Lorex 8 Channel POE 4k Ultra HD NVR. You will need to purchase a NOCTUA NF-A4x20 FLX premium-quality quiet 40mm fan for the swap. www.amazon.com...
Also to Soldier the wires I've included a link • How to Solder Wires To... . Or just twist ties them like I did.
Thanks for the fan part number. Ordered one.
Another quick fix is to take the fan out, peel back the label, put a drop of oil on the bearing and put the label back on.
It was good to see the WD purple drive in there. That's a surveillance rated drive. Good to see Lorex isn't cutting corners.
He probably supplied those himself.
Yeah same i purchased the hard drive for mine too i forgot what it came with or if it came with one
There was no need to splice it, take a needle or something else with a small tip and you can release the pins from the plug and arrange them as needed. The 2, 3, and 4 pin plugs will plug into the 2 pin receptacle.
Please elaborate.
@@adriancitort The 2,3&4 pin connectors will physically fit into the 2 conductor plug. Position them as needed by releasing the pins with a paperclip. I'm replying by memory so if this isn't clear enough I'll re-watch the video and reply, hopefully, more clearly.
my Lorex DVR sounded like a diesel, I sprayed some WD40 from the outside several times and completely cured the problem. Two weeks now and it is silente than ever!!
More than likely you lubricated the bearings.Glad it works. Seeing as how WD40 is still patented. I'm not sure WD40 is conductible. So I wouldn't recommend.
ThankYou for the great information! Too many systems are sold noisy these days.
Dong Ha Hey! Thanks for the feedback. I hope this video helps! If you have any questions, I'm happy to answer them for you.
I pulled my fan out and flipped it over so it blows in. Then I sniped the grid off and trimmed it so 100% of the fan blade is uncovered. This is good for about a 40% reduction in noise.
After 2 years, how's that working out for you?
@@lobes187 As others have indicated, flipping the fan over does help reduce the noise somewhat... but I wouldn't recommend it. Once flipped you care now sucking unfiltered air and dust "into" the machine. Over time it can cause components, processors, HDD's etc to over heat or fail due to dust collecting on them. If you do decide to flip the fan then you should plan on going through the hassle of taking the unit apart every 6 months or so to blow out all the dirt and dust bunnies.
🇨🇮 You are very good to come back to me, I had to give up and reinstall the original fan. The Noctua fan would not run for me. It just move slightly and then stop. I had tried 2 different fans without any luck. Many thanks again.
Same behavior for my NVR. I contacted Noctua last year, they only replied to say their fan does not support the low startup voltage of the delta power supply. I use vacuum hose to reach in my server cabinet to suck/start my Noctua fan and then it runs fine. My NVR is on a UPS but if power goes out long enough maybe it will start after a minute or two. Next time i pull my Lorex NVR out, I may replace power supply fan with a 5V USB version similar to comment from Javier. Also replaced the 40mm x 10mm with Noctua fan on the mother board and it starts up no problems.
Thank you for your reply you are very good to do so. I will have a look at it again, kind regards. 🇮🇪
This could be a replacement . AC Infinity AI-MPF40A is - Dimensions: 1.6 x 1.6 x 0.8 in. | Airflow: 12 CFM | Noise: 18 dBA| Bearings: Dual Ball
How has cooling been as that was the reason I didn't install it in my related video documenting the noise output of the same NVR? Initially I thought it would be a good match as I misread the specs of the NOCTUA NF-A4x20 FLX vs the stock DELTA EBF 0412 HHD. Was OK with the RPM drop from 8200 to 5000 as figured that is what set up the 14.9dB vs the 30.5dB. Misread airflow as saw 9.4 and 9.43 but didn't realize was 9.4 m3h vs 9.43 CFM. When I caught that as I was about to assemble, the conversion is 9.4 m3h = 5.53 CFM which is about a 40% reduction in airflow. That is when I was afraid it wouldn't cool enough for the engineered specs. I did notice the 2 pin vs 3 pin but didn't get that far.
I looked for other 3rd party fans that were low dB but couldn't find any with the airflow. As a result, yesterday I requested a return (4 days before the 60 day window) and will probably build out a minimal Core i5/i7 machine with Blue Iris dedicated to cameras or if the NVR route purchase the Dahua NVR5216-4KS2 unit who appears to build them for Lorex but the version without the internal power supply. With either the computer/Blue Iris or the NVR would use an external fanless PoE switch as it is the convenience of the internal PoE capable switch that creates the problem. That should be very quiet.
Interesting. I've built computers before. I built the one I'm typing on right now, and its silent. Might be something I consider in the future.
What software would I use to control the cameras? How would I connect 8 more ports?
A great source of info is ipcamtalk forum. There are 2 approaches. 1) build a dedicated computer running 24/7 (unlike your normal computer) and can be very basic not requiring high end graphic cards, etc. While there are others, Blue Iris (PC only - not Mac) is the preferred software then add an external network switch that has enough PoE (Power over Internet) ports as you require. Careful, may see 8 port switch but only 4 are PoE so read the specs and realize one port will be monopolized for router linkage so will lose it for a camera. They make some switches that are fanless - up to 16 ports, but most have fans with power requirements above 16 ports mandating fans. Other computers (and Macs) can read remotely with the free NVR software. That is probably the route I am going as it will also let you do other things that the cameras are capable of yet the NVR blocks as not programed in. The other option is the 'simpler' NVR solution. The one reference earlier is actually a 16 port unit but there are no ports built in - just the one network connector and missing the internal power supply with the noisy fan. It would use the same PoE switches as the computer based system as you have essentially moved that portion out of the NVR box and the NVR software is what limits it to 16 cameras. There is a cloesly related Dahua NVR5216-16P-4KS2 model that has the 16 ports built in as well as the same power supply which is what the 16P designates.

Disappointed that you did not let us hear the difference in noise at the end with everything back in place and the cover on. That the fan is quieter when it is on its own and in your hand is a given.
Too late for me. My DVR burned out from the fan not working properly and Lorex did not replace it. This happened 2.5 years after I purchased mine from costco
Hello ivaalia. Have you had any problems with your NVR since replacing the fan? I put the same fan in as you did today. It is definitely silent, but no where near the same air flow. Maybe you really don't need as much as flow as the other fan provided. I do believe that you may have put the fan in backwards though. On mine, the label side was the outflow. I could feel it blowing from that side. I assume the fan should draw air from the outside and blow inward??
Hey Brian! I haven't had. Any issues with the NVR since making this video. I don't remember which way I installed the fan. I'd have to watch the video or check the unit when I get home. Inwards or outwards have been a debate for a long time. There are videos of people doing tests to see which is the best orientation. It's really a matter of dust getting into the unit with either too much negative or positive pressure with the orientation of the fans. That's usually with large computer cases with multiple fans. Since this is two small fans, with one being enclosed for the power supply. I think I chose to have the pressure negative and blowing out. Again, I'd have to double check. It should be fine either way.
@@ivraalia Thank Ivraalia. I just checked the one that I pulled out and it was definitely blowing out. I know that the label on the fan was facing outward. I just hooked it up to a 9V battery and the label side blows out. Damn, now I have to take this think apart again....
Amazon has two versions of this fan, a 5v and 12v. What one did you get?
I bought the 12V. They didn’t have the 5v available back in 2017. I’d say 5v but the 12v worked for me and it’s $5 cheaper at the moment.
@@ivraalia Are there any benefits of the 12v over the 5v? What was the stock fan? Thanks for the video, BTW!
@@J0r Sorry, I don’t remember the stock fan.
I believe the benefits for the 12v is that if you need the fan to spin faster it’s more capable. I doubt you’ll need to though. That NVR doesn’t have fan speed controls.
My pleasure brother 🤙🏻
Hello
i m gonna buy CCTV but i m nt so much familiar , how s ur lorex 8ch 4k system???compare than Amcrest/Swann/....
how s the quality of body of camera ? coz i saw a video for Lorex camrea which is broken .
and also is it really clrear for this 4k and that price??
tnx
would like to do the same for my HIKVISION DS-7608NI-E2/8P. Can you advise which Noctua fan model will replace my stock fan? Would the NF-A4x20 FLX be that fan?
Hey George, based off the information you've given me I found your model. I can't find any specs on what fans they use. If you could open the unit up and snap a picture I could be more helpful.
For the Hikvision, that fan will not work. Here's a video that will replace the fan in the Hikvision. th-cam.com/video/gKbeokSp3f0/w-d-xo.html
When connect the black factory fan it works.
Hey David, I had the same problem and spent a good deal of time checking and re-checking everything. I noticed if I waited around a 20 seconds to a minute, the fan would start on it's own and keep running. I contacted Nochtua, and they replied, but were not really much help. Mine seems to be working fine after 24hr so far.
Mine is ridiculous
please I need Firmware for lorex LNK7232-N, (LNK7000series). can you help?
This is the quickest thing I could find.

Hi I cannot get the new Fan to spin, it is the NF-A4X20 FLX Noctua fan. Is it a case of the red wire to the red wire and black to black. What happens to the yellow wire. Kind Regards.
Hi Very sorry about my delayed response. The holidays have got me running around.
The red and black wire are the circuit, and the yellow wire is for speed control I believe. The unit only has one fan speed so the yellow wire isn't used.
It a computer case, mother boards can control how fast, and when the fan spins.
Happy belated Thanksgiving and Merry Christmas!
Mine isn't spinning either. I did red to red and black to black too. Did you fix this? If so what is the solution? Thanks
Thank you for your reply, I was unable to get the fan to spin. A fellow utuber said to leave the fan powered on and it will spin after a short time. I was not happy to try this as I could not trust this fan to work all the time. I positioned the DVR in a location were the fan noise is not a distraction. I can still hear the old fan running but it is not as loud and reassuring. 🇮🇪
@@davidryan6616 Mine turned on too after a while but it was very weak and not much wind at all. Wonder why it does this...
@@amzbuyer The yellow wire is for a connection to a motherboard of a computer to allow the speed to be monitored by bios. In our case we don't need the yellow wire just the red and black 🙂🇮🇪
What do you do with the yellow wire
Did you get a reply about the yellow wire, my fan won't spin. Thanks.
@@davidryan6616 no
I think we are too late with our questions.
Surly someone with half a brain would plug the power cord in before the fan..
The sad part is that little baggy he just threw was for making an adapter lol
trenidad zambrano Haha Nice catch! I thought that happened when I did a watch through.
Yeah, he could have cut the old fan header off and connected it to the new fan adaptor using the supplied gel clip connectors.
