I've just placed an order for the NX3000 and I'm so glad I watched this before it arrives. I was aware of the loud fan and knew that quiet replacements were available. Seems straightforward enough. Thanks for posting!!
I use Noctua fans in all of my gear including my server, gaming pc, POE switch and 4bay hard drive enclosure. My amps and processer are cooled by A/C Infinity fans that are very quiet as well. So, good choice.
That is significantly less airflow 3:45 vs 10:14. But I guess these aren’t really pushed to their limits. Maybe if you’re running lots of sub 20hz content it’ll get too hot. I doubt you’ll overheat it though, there should be a protection internally anyway.
This video is a lifesaver! I'm planning on geting the NX3000D for black friday along with a couple of tactile transducers. I'm also a complete newbie on the electrical stuff and got very confused about the 4 vs 2 pin cables. I was like, "what model are all these people using? they're not compatible! Or maybe they're using an adapter? Why don't they mention which one?". This video cleared it all up. Thank you very much!
Thanks a bunch man :) I recently got my hands on a Hybrid A-1600 (Unlike QSC, Crown and Behringer, Hybrid is a brand you probably have never heard of as it is primarily manufactured for the South African market lmao) with a fan (actually 2, one on either side of the amp) equally as noisy, was busy looking over several options stressing over different CFM and shit. This video really helped :)
@@TyEichele hey man! i decided to come back and ask regarding your modded NX3000, have you encountered any problems such the amp going into protect mode from overheating or any other problems alike? or is it still performing well?
52 vs. 19.5 That's the CFM rating of the 2 fans. Sure one is much quieter because it's pushing a little more than 1/3 the volume of air past the heat sink of the Amp.
You can use a resistor in series if you want to slow this fan down a bit. It may even come with a "Low noise adapter" as many Noctua fans do stock in which case you can just make a small adapter cable and use the stock noctua fan cable and LNA. I suspect those of us using this type of amp on a home sub will not be driving it at high enough duty to really stress it and heat it up too much. I'm sure if I look around someone generous will have tested this and published passive cooled temps vs fan operated.
@@TyEichele Happy to! It's been my journey with silent computing and home servers that sound like jet turbines haha. Noctua gear is the best at market for this type of use I think and I like that they generally include the extras to cover the noise generated.
You now have half the air flow I would not do this for a live band set up. If the fan is loud contact Behringer they will take care of it. I have all Behringer amps I have never seen this problem. But any problems I have had Behringer has taken care of the product. The only problem I had was my guitar player broke my x32. Otherwise none of the Behringer products I've ever failed and I've been using them since 2001. I have the 3000 watt version like you have and I have the four channel amp as well and they're both dead quiet.
Also, it's important if you're going to switch out the fan. Make sure that they're pulling the same amount of power. You don't want to put a fan and that pulls more power than the original fan. It does appear that you're flowing about half the airflow and if that amp was under a heavy load it would probably burn up
Jamicon es una marca profesional de mucho prestigio, pero ruidosa. Lo mejor es ventilar doble el sistema. Dejar por dentro uno que apunte diréctamente a los disipadores y el de afuera para introducir aire fresco. Y ambos de velocidades de 1200/1500 rv minuto. Es importante repartir el aire de dentro para quitar calor al disipador. Otra idea es cambiar el disipador por otro más grande y de cobre. Eso haría que el semiconductor concentrara el calor en un punto.
Maybe you should write on English ? How do you know that this guy knows Spanish language or whatever this is...? But you are 100% right 👍 about two points of entry... one to suck in fresh air and other to rotate out the nasty air from inside. But the point that this person had was noise and he solved it so 👏bravo
hi thank you so much for your excellent video I would love to have your opinion about the NX3000 amp sound is it valid also for a basic stereo system ? thanks a lot bye gino
I did this mod on a Inuke6000DSP, and the amp is shutting down after 10 min of being open, with no sound/music playing. I'm measuring 6v on the connector on the pin on the board tho.
Thank you! I would not change voltage of fans, especially if it is designed for a specific voltage to begin with. That's just me, maybe someone else can explain why or if it is ok, but to me that is asking for problems when you start changing stuff like that. I'd try my best to stick with a quieter 24 volt fan that matches that current one.
I am using it for subwoofers, yes. I would look up the specs of the l/r speakers and the specs of this or any amp you may decide on to see if you can wire it into a 6ohm load properly at the correct power levels to prevent damage to the speakers.
The limited light never lights up that I see. I also have the volume knobs fully turned up as far as they will go, then I let the MiniDSP and the subwoofer out in the AVR handle the sub volume from there. The only time a red LED comes on that I notice is when I first power up the amp and the 'protect' led lights up for a brief second and then goes off.
This means that the voltage coming into your power amp is greater than the rated input sensitivity (the voltage at which the amplifier creates full power before clipping). When you turn the knob down at the amp, you are attenuating or reducing the input signal voltage. You can reduce the voltage (gain) of you input source, or you can attenuate the voltage at the power amp with the knob. Ideally you would match the voltage of your source to the input sensitivity of the amp, but in reality this isn't always possible. It's better to have too great a voltage coming into the amp (since you can attenuate with the knob) vs too little (you will not get full power out of the amp).
@@skrillavilla That's a great explanation - thank you! I'm still not seeing the limit LED light up. The only thing I notice in the video are the two top red LED's next to 'Protect' on the amp, but they only come on during the intital startup of the amp when I first turn it on. I don't even have a source (Denon AVR) turned on in this video so there is literally no input coming into this power amp. I think the previous comments are seeing the red protect LED come on at startup and getting it confused possibly.....?
Hopefully! But it also seems that no one has really had any issues after swapping to a quieter fan either so I have my hopes up for no issues long term. I feel there is still good airflow coming out of the vents even if it's less. Thanks for watching!

Glad it can be of some help!
you should even be able to set the speed of the fan, that is how they are set up in a PC. This fan is always on - lazy engineering design ☺
Thanks for the video.. So much better after the mod!
I couldn't agree more! 👍

That's great to hear! I've read and heard nothing but good things about them. Thanks for watching!

Happy to report that I haven't had any issues so far!
Yeah that is always my problem with noctua videos...sure they are quite but also pushing very little air

cant help wondering... if a intake tube can be made for a remote larger fan 125mm quite fan. lol!
really great share!

hi thank you so much for your excellent video I would love to have your opinion about the NX3000 amp sound
is it valid also for a basic stereo system ? thanks a lot bye gino
It's ok for basic stereo yes. If it meets your power requirements then go for it. It's underpowered for what it's rated at, but works.
@@TyEichele hi thank you for the very kind and helpful reply I see that is stable even with a 2 ohm load
This is good Kind regards gino
I did this mod on a Inuke6000DSP, and the amp is shutting down after 10 min of being open, with no sound/music playing. I'm measuring 6v on the connector on the pin on the board tho.
Do you know if you can use a 12 volt fan on an amp that uses a 24 volt fan? I have a QSC that I think uses a 24 volt fan. Great video btw.
Thank you! I would not change voltage of fans, especially if it is designed for a specific voltage to begin with. That's just me, maybe someone else can explain why or if it is ok, but to me that is asking for problems when you start changing stuff like that.

Are you using that amp for a subwoofer? Is it possible tonuse it for front l/r speakers that are 6ohm? Thanks!
I am using it for subwoofers, yes. I would look up the specs of the l/r speakers and the specs of this or any amp you may decide on to see if you can wire it into a 6ohm load properly at the correct power levels to prevent damage to the speakers.
question, why does the limited led often light up even though the volume is at 12 o'clock

@@TyEichele not your amp sir, I have an nx6000 and I see the Led limiter flashing even though it has not reached the maximum level

Yeah looks like it’s so quiet because it’s not moving nearly as much air. Hopefully it’s not a long term problem with amp life.
Hopefully! But it also seems that no one has really had any issues after swapping to a quieter fan either so I have my hopes up for no issues long term. I feel there is still good airflow coming out of the vents even if it's less. Thanks for watching!
El ventilador nuevo, tiene mucha menos potencia y caudal de aire.
Air flow looks liss not good
