The difference is UNBELIEVEABLE! I had to double check that the fan was running because it is so quiet now. Thank You!. Also... ditto on the comments about the connector. I bent my pins a little to fit it in due to a chip on the board being too close to allow room for the unused wire on the connector. I could have also soldered the old connector on the new cable, but this worked fine. Just caution to anyone reading this... If you break your pins on the board, you're going to have a Bad Time.
Thank you so much for the video, it was very useful. When I modded mine, I did find the cable that ran from the FAN to the board pretty hard to fit, especially with the FAN in situ. So, I used one of the provided 'additional' cables and fitted that in place, whilst the FAN was not present - so I could access through the hole where the FAN would have been. As this was for a three pin connector ( red / black / yellow ) it was a little too large for the space available, so with the aid of a magnifying glass and a plastic spatular I eased the two pin from the mother board to the right a little. Then used a pair of angled pliers to fit the cable. Then I installed the fan and after this connected the cable from the FAN to the new cable sticking up off the motherboard. I found it easer to pop the fan ducting shield thing AFTER fitting the fan back in place. It meant I could get hold of the fan better when I screwed it back into place, otherwise the FAN itself is pushed back and away from the mounting holes. Once again, thanks for your time and effort in helping others.
One note: It's important for the fan to push air into the amp chassis from behind for the best cooling, because the amp has minimal heatsinking of the output devices, so it depends on having that airflow. The job of the air duct is to guide the airflow across the PCB surface while increasing the speed of the air, and this is especially important when you use a slower running fan for lower noise. So be sure to also re-use the air duct. The NX3000 models do improve upon the previous NU3000 models in the area of heatsinking; the previous models did not have the aluminum bar for a heatsink, just bent copper wings that were soldered between the output transistors and the PCB surface.
when you say air duct do you mean the piece of black plastic that was attached to the old fan? also, are you saying i should have switched around the fan so it blows into the amp instead of out? Thanks for your response!
@@TheLegendaryBrownNote Hi, yes I was referring to the black plastic. It is used as an air duct to direct cooling air over the heat sink, which is the aluminum bar underneath it. This way, a smaller heat sink can be used. Based on the video, it looks like you do have air blowing the correct direction; it should be drawing air into the chassis from behind, and out of the vents at the front. Air blows toward the label side of the fan.
I guess this makes sense if it's for home use but for loud event applications the environment will already be loud. Pretty cool mod, seems somewhat easy, I got a NX3000 myself .cool stuff.
I've now done a fan mod upgrade to a NU1000DSP using the Noctua NF-R8 Redux 1200rpm fan, and it is a good choice for this application. It reduced fan noise to inaudible from more than a few cm away, and the coil hiss from the switching power supply is more audible than the airflow from the front side of the amp - again, with my ear right up to the grille. The fan is able to spin up on the voltage from the amp at idle, so stalling is not an issue. I'm using the NU1000DSP to push a Bag End S10E-I subwoofer with a complementary response curve to the ELF alignment of the sealed box. The only downside is the NU1000DSP's input sensitivity is not high, being a pro amp, so it needs an inline unbalanced-to-balanced preamp like ART Cleanbox to raise the input to a usable level. But I have all the power needed for this power-hungry small monitoring subwoofer setup.
Awsome video man, I just installed the same fan in mine and its so quiet! I also mounted the anti-vibration mounts and using a plier it wasn't that difficult.
that's so awesome! i haven't noticed any noise from the fan so far but good to know that you can put the anti-vibration mounts on! enjoy the nice and quiet :)
Legitness. I'll need to look into doing this, I've got 3 NX4-6000s so the fan noise stacks up quickly. I've found it becomes white noise because I never turn off my amps but having them be quiet would be nice. I wish I knew which fans my Pyle PT8000CH uses, that thing makes NO NOISE, it's super impressive. I'll look into this.
you must have your amps pretty far away from your mlp if it disappears as white noise!!! With the old fan when there was loud action it wasn't noticeable but as soon as it quiets down it was super distracting! i'm glad there was a solution. It's amazing they ship with such loud fans! have fun if you choose to do this mod! it still boggles my mind how much power and wooferage you have running!!
@@TheLegendaryBrownNote HAHA! Thank you, I really enjoy consistent deep bass! The fan sound kinda fades into the background 1. Due to the size of the room 2. Because I never turn my amps off. So when you walk down they're already going so the brain starts to cancel them out. Maybe the NX4 is a bit quieter than the 3000? I doubt it, though. To your point, one of my amps is at the back of the theater, about 25 feet from the front row, so that helps. The other two are probably 3 or 4 feet from my seat. I've considered putting my amps at ground level (in terms of acoustic physics, that will cut noise down) but the dust they'd collect would be scary. RE: Wooferage (I love that word by the way, definitely stealing that), it's about to get crazier! Once our funds settle back down and I get some spare cash, I'm going to buy 5 of those new Dayton 21" drivers and build some IB enclosures for em. If they're as good as I think they'll be, I'm going to sell my 15s and they will become new staples in my setup. So I'll have 8 18s and 5 21s. If they're THAT good, I'll probably sell my 18s and replace them with the 21s so I'll have 13 21" drivers . . .that's going to be ABSURD! I think you'll need to fly in to Indiana to experience that one!
@@budgetaudiophile6048 lol i love the craziness that is your room. I've never been to Indiana! I can cross that off my list when you get your new setup!
i was hoping for a bit more data, like what was the internal temps before and after swap, what is the before / after CFM (airflow). Id love to believe this is all just fine, but I will do a bit more science before cooking my amp.
@@GurvanBHC7 This is just ignorant. Look up the specifications. The Noctua has 1/2 the air flow CFM that the stock fan has. the Stock Jamicon fan is rated at 54CFM the Nocuta a8FLX is 24CFM.
do you have any issues with the amp ? i am a power user and i will use it 80% of the power all the time , also i did the change with arctic f8 fan , it's a lot cheaper and about the same noise as noctua does
i do not remove the 2 pin socket. i was able to wiggle the new connector over the two existing pins. some other users have reported that they had to bend the pins slightly to allow for the new fan connector to go on.
Sì, la nuova ventola non spinge più aria della vecchia ventola ma non ho avuto problemi di surriscaldamento. Sto spingendo l'nx3000d a volumi alti e pesanti e non è ancora entrato in modalità di protezione.
i have a nx6000 and is the second time that i push the botom on and nothing hapen no leds no fans nothing... then days before this on and work well make me crazy i dont know wath to do
Здравствуйте! Может Вы сможете мне помочь... Скажите,этот усилитель может выдавать частоты от 5 Гц до 20 Гц? Я хочу подключить к нему вибро сабвуфер buttkiker именно для этих частот. В инструкции написано от 20 ГЦ, но это для эквалайзера,а ниже они отрезали что ли?) Заранее Вам благодарен!
@@AzzzNostr theres a switch mode power supply inside this amp on the right section if you watching it from the front. Voltage level are unable to change by user. However i remember that somebody made a video of the older nu series where you can change the levels by soldering something on the supply section. And as everybody knows, nx is nu, the difference is only the box around the pcb.
I did remove the 2 pin socket the new plug fits quite snug against a component on the mb so I don't think it's going anywhere. All works fine after a couple of hours use the case feels cool to the touch
@@TheLegendaryBrownNote Great thanks! btw the PWM fan actually turned out to be better because it has higher CFM and static pressure and even higher rpm. The connector needs to be cut but worked like a charm. Fan Noise is not audible
Is the new fan quieter because its a slower speed? Or are they the same speed? Can the fan just be removed and not replaced if you dont run the amp at full power?
the fan is running at a slower speed yes, and it's quieter because noctua is known to be a quiet fan. I would not feel safe running it without a fan. But that's just me.
@@ProfessorJohnSmith i'm not sure. i've never felt or measured the temps inside. i've put my hand on the top of the amp and it feels fine. I've also run the amp at full load for heavy movie scenes and no problems yet!

you're welcome! I hope you have a nice quiet amp soon!
I have got to do this for my NX3000. I’ve got mine behind a glass door that quiets it down some, but it is still noticeable.
definitely worth the upgrade! only takes about 30-60mins!
@@TheLegendaryBrownNote question, your description says the NF-A8 FLX, but the link goes towards the PWM. Which one is the correct one?
@@Animal1984 as far as i know the last three letters determine how fast the fan spins and from my research they will all work.

Thank God the lab pdx 3000 looks better built, was worried it was a rebaged Behringer...
Yes, and the original fan is 52 CFM and the noctua is 30CFM max. So the amp will die on you, if there will be some amps.
i was hoping for a bit more data, like what was the internal temps before and after swap, what is the before / after CFM (airflow).
Id love to believe this is all just fine, but I will do a bit more science before cooking my amp.
trust me, the stock fan had way less CFM than the Noctua for sure ! All stock fan are bad...

I definitely will replace the fan, it's pretty loud.
No issues with needing to bend the pins to get connector on? I guess each one might have slightly different clearances?
i might have bent it inadvertently when slipping the connector on but i'm not sure. All I know is it's very cramped in that space!
do you have any issues with the amp ? i am a power user and i will use it 80% of the power all the time , also i did the change with arctic f8 fan , it's a lot cheaper and about the same noise as noctua does
could you just splice the wire, leave the pin connector and glue as is and solder/braid the new fan wires to the old ones?
this is beyond my expertise so sadly i can't help you with this answer. good luck with it tho!
Yes you can, but it's easier to do it the way he did in the video and then hot gluing the connector back down into place.
I always wondered why ppl complain about fan nose on amps when amps are meant to be play loud and make boom sounds lol 😂
My Behringer 3000 is making a popping noise when I hooked up a 16ohm shaker and it is now not working, do you know what happened? Is the fuse broken?
thank you for sharing, whats the standby power usage of the amp?
hey there. i'm not sure as i've never measured it. sorry!
Do you remove the 2 pin fan socket when you unplug the original fan otherwise I cannot see how the 3 pin plug fits into the motherboard?
i do not remove the 2 pin socket. i was able to wiggle the new connector over the two existing pins. some other users have reported that they had to bend the pins slightly to allow for the new fan connector to go on.
