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

hey great!

i think the industrial fans including adda have a rough ball bearing. (rattle)
so the noiseblocker pro fans a extremly smooth.. but only 12V..

even I'm torn here between the Inuke 6000 and Thomann t.amp TA2400 MK-X (2x1200W @4ohm ring core >23KG)
so the weight is not my problem its mounted in a homecinema subwoofer.
the inuke 3000 have only 6xxW @4ohm ....

I think the issue is the speed of the fan creating turbulence through the front louvres, not the fan itself. The lower powered fans are quieter because they spin more slowly & dont get ramped up as much as the Behringer fan. But Behringer is trying to cool this thing during PA applications which is what it was designed for, so noise wasnt their main priority. In any case, you will hear the rushing air which makes a droning sound before you hear the fan itself.

Must point out this mod relates to my NU3000DSP

Ahh, this might explain some things! Can it be that NU3000 has variable fanspeed, while the NU1000
goes at full fan speed from start? (as my NU1000 does)

The specifications state that all three models have variable fanspeed, but my specimen certainly has not...

I put the heatsinks on because I cut the fan speed rotation....I am hoping it will compensate.
For professional use I guess the high speed fan works. The 3000 differs from the 1000 in having metal stand-offs which act as heatsinks, although they are not finned.

The 3000 is certainly SCARY when the fan is running at full speed!

i think full metal blocks a heatsinks are not a good idea!
heatthink without cooling fins...

i think for really home cinema use they must be under 20db!

with onyl 1 fan is this a little bit unpossible

i built my subwoofer case with integrates 2HE 19" slot.
so i can put the AMP in the front an then the front is sealed!

the originalfan was remove or disabled.
the components on the mainboard which was hot (measure with IR/Laser Thermometer) become big heatsinks.

now on the bag side of my 19" slot i will built a fan array.
4-8 80mm or 92mm Fans with an integrated 12V notebook Powersupply.
so every fan produce... 12-14db noise.

the array put 2-3 times more air through the amp.

strictly along the lines of:
who cools good... the run is good

as a waste product, I've got a perfectly chilled and inaudible even under full load amp.

so i will make a photo..

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

I must say that my iNukes has blown me away! Even the treble is quite acceptable!
I use it on full dipole speakers with four Peerless 12" sls bass drivers in a folded dipole, a Dayton RS-180 mid and a Neo3 treble per channel. One iNuke 1000 for the bass and one for mid and treble. Using Holm measurement program and a Panasonic wm-61 mic, I have achieved a very nice sounding frequency curve, using the built in DSP. My plan is to rebuild those speakers so that the eye (wife) also likes them, will send pictures when ready...
