Re: Behringer iNuke NU1000 Amp Amplifier Fan Swap How To w/ PICS

What is the exact size (diameter and thickness) of the stock fan in the iNuke 3000DSP and is it 12V or 24V?

Re: Behringer iNuke NU1000 Amp Amplifier Fan Swap How To w/ PICS

is a 80mm standart 24V DC Fan.
thickness 25mm

i have tested the inuke 3000dsp today..
i send it back to the dealer this amp is really terrible

1. the DSP version is hissing after power up more then 40%..
2. the 2 channels are not really symmetrical... for 2 identical subwoofer i need on the first channel 100% power and on the second channel only 70% for the same loudness...

the amp is good for paper weight but not for hifi!

sorry

The fan is 12v not 24v ?

I have a inuke3000 for both of my Dual Opposed sub builds ie one for each build and I think they are great.

Two Fi Q15's in a 120 L cabinet sealed and those inuke3000 drives them hard.

24V DC Fan! 80x80x25mm!

in the Inuke 3000 you can use one! Fan Power port on the Mainboard. (the second one is unusable)...
you can use 2x 12V Fans in in series..
(Mainboard + -> + Fan1
Mainboard - -> - Fan 2!
Fan 1 - -> Fan 2 +)

now its 24V

12V fans are much common than the 24V fans and much more quiet.. (Noisblocker Fans have very silent Bearings.. Enermax, Arctic Coolung.... with FDB Bearing are also good but the tolerance in the FDB Bearing i find is too much.. so you get one silent fan and one with an rattle bearing.. )

Thanks, I'll go for the Papst 8414NGL fan, the same one I have used previously in a Behringer EP2500. It's virtually inaudible.

Re: Behringer iNuke NU1000 Amp Amplifier Fan Swap How To w/ PICS

i dont like the papst fans...
they are not enough silent for me 15db is max for me
and the papst fans... I think they are the inventors of the cruel and rattling going out of round ball bearings.
Moreover, just overpriced for what deliver the scrap.
papst treated the PC market since 8 years focused only very neglected and focused only on industrial fan.
and because it comes on quiet ball bearing and wind noise, not to the rotor blades on it.

on the tech paper!

every 10-14db papst fans i had was louder as good 18-20db fans from noisblocker
Buy fan is in a sense, also a matter of experience.
papsst fans have loud bearings....

sorry my english is not the best i will say:
papst fan in the airflow is indeed low but the stock is so annoying noise the fan with a louder sounds quieter bearings easier on the human ear.

good friend from me is www.ichbinleise.de
they sell massiv fans and built silent pcs... they now whitch fan is silent...

I got my iNuke NU3000DSP today and the first thing I did was open it up. Much easier than the old EP2500.
The stock Fan is labeled 12V so I'm real confused now as apparently there are also iNuke's around with 24V fans?

I can get a silent 12V fan for €3,- but a silent 24V is much harder to get and the only option I've found where I live (the Netherlands) is the Papst 8414NGL for €22,-.

I quickly connected my PC and updated the firmware and played around a little with the SP software. It's pretty straightforward.

The only drawback is that the Behringer doesn't fit inside my rack so I'll probably have to put somewhere it on top.
