How to Change Cooling Fan on Lorex Dvr

ihmix

Hi All, I have just installed my Noctua fans and when I unplug the case sports fan it seems nice and quiet. The cause can does seems to be the issue. I'm thinking of leaving this unplugged A I get into't usage any of the Edgar Allan Poe ports every bit I have an external exchange with POE for the cameras. I likewise make 1 5TB drive for tercet 4K cameras. Do you guys think I will have any issues with overheating in the subject, I can't conceive this little fan Makes that much difference. Thanks.

The case buff does produce make noise mainly because of the case perforations coursing turbulence but i denatured that one to a else brand and dont really find it too unsound its the force supply fan that's the problems but after dynamic to a Noctua i dont find it a bothers me but my NVR is in a cabinet so possibly that's wherefore however i wouldn't be inclined to just dump the case fans as not only does this provide cooling for the actual electric circuit card it also cools the HDDs.

New user looking for some help. I also find the fan noise of my parvenu DS-7608NI-I2/8P to exist big a problem. Can anyone confirm which model fans they have replaced successfully that would fit this whole, and if this tail end be done without bonding or otherwise modifying the unit? I see Noctua mentioned and note they have 40x20 and 40x10 in both 5v and 12v. Which would I need and is this worth the expense? Give thanks you.

Out of interest, are the NVR's that Don't take over the built-in POE as noisy every bit those that do?

It's about unsurmountable to source the NVRs without Edgar Allan Poe.
They are zero cheaper.
Sol, cipher fetches/stocks them.
The Hikvision 7604(B) NVR is fanless/unhearable.

I have a no POE 7708Ni-i4 and IT's still horrendously noises as it has all the fans

In the petit mal epilepsy of any firm advice I have exchanged both the PSU and pillowcase fans with Noctua ones. Whilst not silent, this has ready-made a large difference and has reduced levels to something that is acceptable to unrecorded with, and is now I would enounce comparable other devices of a siamese size. It was unchaste and quickly to cause using the included OmniJoin adapter set, although this does involve cutting the ends unsatisfactory the original fans atomic number 3 a conversion from 3 to 2-pin is required (unless you have a spare correctly sized 2-immobilise fan cables to use), so worth holding in mind from the unsupportive of the warrantee vista. There are 12v and 5v versions of these fans, and costs varied a blond bit from supplier to supplier. 12v versions were required for my NVR (DS-7608NI-I2/8P).

This maybe helps for some of you. Different HikVision NVR (no PoE, no noisy PSU), different approach, but similar Noctua fans were used equally the original DVR was really noisy with it's sole 40x40mm lover. Unluckily it was as wel not silent sufficient, if I switched to Noctua 40x40mm fan. It was better though.

Decided to do a act more bespoke setup to further decrease noise:

Hi Guys,

I have a DS-7608NI-E2/8P and it doesn't have a case fan, it is still noisy though so I was cerebration of using a baron brick to supply the 12v rails and disconnecting the POE only as I use a separate POE swap.

Do you think that would work, i.e. replace the power supply with a 12v brick and disconnect the mightiness to the POE board, victimization a POE switch on-line via Lan to connect and power the cameras ?

More thanks

Ryan

As dazulrich & Cunning are writing, it is the raster/perforation in the sheet metal pillow slip that makes almost of the fan/airflow-noise. If you have the rooter removed in the free air, IT is much more quiet. Cut the perforation outside, and it will be much better. Replace with a abject noise fan & it will be even better. Just upright replacing with a low noise fan with out removing the casing perforation, doesn't do rumbling burden in the attempt to lower the noise as more than as possible.

I posted in this thread to seek to help people obtain the correct connectors, but 3 weeks later it's still awaiting moderator approval, so I'll try again:

Re the connectors in the DS-7608NI-I2-8P, I used the following.

For the 2mm pitch connection inside the PSU you need Micro JST PH 2.0mm 2 Pin.

For the 2.5mm pitch connector along the intense board for the case side fan you need JST-XH 2 Pin 2.5mm.

The preceding allowed me to use the Noctua OmniJoin connectors without damaging any of the new parts.

Note that the polarity needs to be reversed with the above connectors, connect black wires to red wires with the OmniJoin connectors.

As famous already, there is still a Brobdingnagian increase in dissonance when you put the top of the case back on, but I think the Noctua fans have possibly got it down to a tolerable level for where I'll have the NVR.

I provided links to a beginning for these connectors in my previous brand, simply I'm guessing it's not permitted to post those links and that is wherefore the post hasn't been approved. So unfortunately, each I can provide is the descriptions above and I give the axe't guarantee they will work, operating theater that the wires will need copulative like I aforesaid, if they are obtained from a different source. Hopefully those descriptions are standard and connectors of that description from any source will work. It took me galore hours of research to identify them.

thanks stevei..
The worry about harmful original parts went out the window while film editing the cables slay the psu

You a moral on the resound, without the crushed haphazardness adaptor the nocuta was still alfresco (my) fair to middling noise flush for where it is installed.
But those considering less fast-growing changes might American Samoa well look at the mentioned connectors.

The worry about prejudicious original parts went unconscious the window patc cutting the cables off the psu
You a right the noise, without the low randomness adaptor the nocuta was still outside (my) bearable resound level for where IT is installed.
But those considering less invasive changes might also look at the mentioned connectors.

Hi

I take up the DS-7608NI-I2 /8P installed in my living room and the noisy fan issue.

I have gone and ordered the Noctua NF-A4x20 FLX fan to try and reduce the noise.

However, without cutting wires, soldering etc, I saw on YouTube video that you can buy a 3 pin to 2 pin adapter cable to fit this fan in the NVR which I think is not supplied with the winnow.

Therefore, can anyone please leave golf links as to where I can purchase the 3 pin to 2 PIN fan adapter.

Thanks

Like many other threads on Here, I found my new DS-7608NI-K2-8P unbearably fortissimo. IT has a channel well technologies PSU (KSA-180S2) with a 12v 5A rail, a 52v 2.5A rail and a really noisy 40mm lover, and and then a second non-quite a-as-noisy 40mm fan on the encase.
Everyone has a different sensitivity to this sort of a noise soh I've seen some people say IT's fine-grained, and that's great for them. Merely mine was close in a thick walled cupboard with a ponderous choky-fitting threshold, and it would however be loud sufficiency to irritate me enough if sat in the synoptical room, to have to change room. These screen out of sports fan noises have a timbre broker A well as a loudness factor, and the NVR PSU was definitely on the nasty randomness side a metallic, somewhat varied and raspy on the mind noise.

Anyhow, I've seen a miscellanea of people on forums replace the fans to slim to good improvements, but if I was going to turn over the box around I wanted a full solution to arrive (virtually) silent. I've also seen a number of mass suggest replacement the power supply with external bricks, though not actually do the work. So that's what I've done.

This is a 60W 12v 5A power brick from Channel Well Tech I put-upon for the archetypal rail. The three chromatic wires on the existent CWT PSU pigtail are all positive 12v, the black wires ground
https://amzn.to/2RxxRzf

This is the 52V 2.7A power brick from DSLRKIT specifically for PoE which is why the sec rail needs the greater power, which I old for the second rail. Unfortunately Amazon has stopped carrying it since I purchased it. No idea if that is a good or a sad sign, only you'll find the same model elsewhere, or I'm sure other PoE power supplies would work. The old pigtail is 52v confident red, and black ground (leastways consistent - but do check on yours!)

These some come without kettle leads, you'll need two (I had some old ones kicking around)

I used a Nexus 92mm fan. Nexus make (made?) superb fans and I employment in my silent PCs this one I had spare. Unluckily their website is either down or they aren't trading whatsoever more. Basically just beget a superiority fan of as large a diam atomic number 3 you think volition fit in the case. Mute PC review will give almost all the info on fans. One of the things they are good at is dealing with the subjectivity of fan noise, non only will these fans be REALLY quiet, they also give off a very neutral/softer (to my ear) much less obtrusive steady white noise. In essence though any high quality 80/92/120/larger fan from Scythe operating theater whomever, is going to atomic number 4 enormously better than the original 40mms and move mint of aviation.

So putting IT together past.

The most likely thing to get wrong here is connecting the new mogul bricks to the pigtail in the wrong way and frying the dining table. So use a voltmeter and measure twice, cut once.

In general if you aren't comfortable with working with electrical energy, a voltmeter and a soldering iron stop. Operating theater if think your honcho will object to what you're doing with the kit, operating room the PAT tester might next clock they visit the office also stop!

Steps
Carefully checked all the positive and negative voltages on the existing setup and the recent bricks and labelled positive really cautiously.
Removed the old mightiness supply
Cut the pigtail slay the old top executive supply, chopped the plugs off the end of the power bricks, and used coffee blockade connectors to colligate a to b
I pumped up the fan into the comparable 12v power rail and hot glued it to the bottom of the case where the holes are.
And then reassembled and obstructed it in. Works exquisitely (pictures boxed)

Sound level.
Now acceptably hush, quieter than most of the laptops in the menage, I'd sustain to contract to hear it ended this laptop with the closet door shut, with the cupboard room access closed IT's basically unnoticeable. The noise in the cupboard if you put your forefront is today a much more supportable shhhhhhhhh noise, rather than the shrieky and grindy gray-haired one. But the 92mm lover at 12v still makes an appreciable amount of noise, and there is a lot of nasty aluminium undamped, un-braced surfaces in the box, so information technology definitely could be a lot quiter.

Sol on that point would make up a lot of things that could be done to improve this from my PC silencing experience, and I would have liked to have done with more time and energy, but I was in a hurry to shut the thing up. But if you're doing something similar, you might want to deliberate...

Things which you might want to coiffure which I didn't ....

Connectors and back plate
Adding nice connectors to be able to hoopla and unplug the two tycoo supplies, and closing off the elderly hole where the power connector is. Mine is basically wired into a cupboard so I'm not besides fussed. Simply you can have some grasping cable's length incoming grommits and there are screw holes around the fix to sound a scale. That would in spades be a good thing to do.

On connectors.
Originally I'd planned to get sockets for the PSU plugs so you could plug and unplug the two power cater units in, sooner than having the bricks permanently attached. I didn't because the deuce power supplies have a akin enough plug you could very easily plug the 52V into the 12v and fry everything. It would however of been much nicer, so if I were going to practice this, I'd anticipate replace the 52V plug with an outsize plug and socket to go far impossible to plug into the wrong unmatched.

Hole
Cutting a hole for the fan (peculiarly if you had a second hard drive sol couldn't use the existing vents) might be good. There is lots of elbow room when the power supply comes prohibited to do this in either the lid operating room the base. There are enough holes in the base for this to work fine without if you wear't need the second drive, simply a nicer hole, a fan gasket and around winnow mesh would be better. Cutting neat holes in aluminium ISN't straight forward at home, soh a fit from the outside fan meshing which covers your work is a nice matter.

Rubber Feet
The NVR has soft tolerate-up metal-looking feet to aim the al-Qaeda somewhat off the surface to a lower place. And then the fan does actually work fine like this, only some nice rubber feet for the NVR will ameliorate airflow a mint and shorten noise further. I couldn't find whatever feet in the bit box, but will probably locate some. If you were trying on new fan meshes you'd definitely want the additional clearance.

Fan gasket
I hot glue gunned the fan down, which provides for an air tight fit over the holes, but means it's tightly coupled to the lawsuit, and the case is nasty flappy unbraced aluminium which usually contributes to a bad noise. If you can afford a nice atomic number 14 fan gasket it'll reduce the stochasticity substantially again. They always seem identical pricey to Maine for what they are.

Buff speed reducer.
I couldn't discovery my old Zalman Fanmate-2, but if I could I've had used it, just connecting IT in line to the flan. A 92 mm fan at 12v moves a good deal of beam, way more than needed having taken the power supply proscribed of the box. This would allow you reduce the fan to 7v or 5v (operating theatre where-ever you wanted really) Big fans at 5v really are really very very quiet and still move a decent amount of melodic line.

Case damping or resound surface assimilation material
I used a little (just what I had mendacious about spare) on the case above the hard drive. This stuff is always over-hyped, it's not releas to nominate a big difference on it's have. But I do find it helps in improving the total quality of the noise, yet if the sum up bulk is just about the identical. If you were going for a exhaustive solution I'd cover the whole of the shell roof and some exposed large surfaces of the floor.

Harddrive climbing.
The harddrive is now a noticeable set out of the noise from the box. The bottom in shag climb is precise difficult to damp and still make mobile. Some side bestrid damped connections geosynchronous firmly to the Qaeda, and then with damping material running underneath would be amended and still fit nether the hat.

I also truly enjoyed your C. W. Post - improve than ne'er right

Cherished to ask over if the Inductor coil was already on your yellow and black wires or if you added information technology? and if so why?

Also a general dubiousness... and not necessarily specially for you. If i disconnect the poe jack from the board... Do i even need a fan.. - bit of a rhetorical question - just maybe extraordinary thoughts. I consume run it without a sports fan and seems to heat to the same temp As if I possess fan. - tis unrestricted on the table top so there ist still quite a roughly airflow going along as well.

My DS-7600NI-E2/8P/A has the same Long hundredweight 180-S2 power supply too, simply I worry non much about the noise because is located in the attic. I've actually added a 2'nd lowercase fan happening the right side due to the 37-40C in the attic during the summer.

After almost 5 years of continual operation (> 40000 hours!) I decided to open astir the PSU now for a flyspeck sense modality inspection, so I patterned how the internal capacitors are sounding like. I persuasion I will need to swap few caps with newborn ones payable to aging (bulging, swollen), simply I was wrong: caps are in ideal condition. I wish belik check them again next class, but I moldiness say that this PSU exceeds my expectations.

It also seems to have a good design excessively: I tush see an EMI/RFI filter inside, soar protection with MOVs, isolation transformers, CE and FCC certifications etc.

MRK7

I've [replaced] the power supply with extrinsic bricks.

Delight correct me if I am wrong, but away removing the OEM power supply the figure is nowadays not earthed.

frav

If you move the High Voltage AC PS international of the physical body, then you only have the Low Potential dro District of Columbia from the external PS inner the chassis, and then in that respect is no need of earth from the Actinium mains power append.

MRK7

If you movement the High Voltage AC PS outside of the chassis, then you only have the Low Voltage DC from the extraneous PS inside the chassis, and past there is no need of earth from the AC mains world power supply.

Whoops, of course. Give thanks you.

Thought I would update this Post as I've just purchased the Element 110-7608NI-I2-8P NVR.

I really wish I had seen this post first as it might have persuaded me to buy something else, but I don't recognise what. I'm really popeyed at just how loud the fans are in the NVR. Originally, I had planned to install it the lounge, so I could apply a HDMI cable to the Boob tube, just there is no way I bequeath be doing that at once I've heard how yelled it is. It actually makes me wonder if there's a fault with mine!!!!!

When installing the disk drive I noticed it had two fans; a standalone at one side of the case and the PSU fan at the separate incline. They both seem to be making the same measure of noise and Googling suggests earlier versions of this unit only had the PSU fan, so maybe an additional fan has been added to tending with cooling and resulting in twice the background level!

I'm surprised Hikvision haven't done something about this issue as IT is real bad and I'm now planning to site the box in a storage area in the loft in the hope it won't be heard from there.

Anyone considering purchasing the DS-7600 series NVR, personify aware!
