INuke 6000DSP Fan Mod - Need Help Quick

post #1 of 47
Thread Starter 
Just got the INuke today and it"s super loud.

Have heard of people performing a fan mod to quiet things down, but I'm on the road and can't find a good reference.

In the sprit of not pissing my wife off anymore than I already do, can someone post up the details on what I need to buy and how I need to go about doing this mod.

Links, details and anything else I can quickly reference would be awesome!

I sincerely doubt you'd hear these fans at all, they are what I used: http://www.bestbuy.com/site/searchpage.jsp?_dyncharset=ISO-8859-1&_dynSessConf=&id=pcat17071&type=page&sc=Global&cp=1&nrp=15&sp=&qp=&list=n&iht=y&usc=All+Categories&ks=960&st=dynex+80mm

Chances are your local Best Buy has a pair in stock.

However, any 80mm case fan will work, if you really wanted you could probably find a quieter fan but the Dynex is near silent. Those OEM fans, they sound like a hair dryer!

The only issue you will find with the mod is that the fan connectors are glued in place. I chose to splice, but I read that you can pull them out - it is a soft glue, like silicon sealant... but you'll want needle-nose pliers to do that.

Aside from that, all you need is a screwdriver... takes 5 minutes.

Nothing but cool air ever came out of the iNuke, even running sine waves near clipping.

Magic coming through in a pinch!!! Thanks bro.

Do you think they sell these kind of fans at Guitar Center?

How many fans do I need?
post #5 of 47
Computer case fans are 12V and almost every amp I've seen uses a 24V fan. Check which it is before buying.
post #6 of 47
You need two fans. You need to go to Best Buy, not Guitar Center. They are 12 V fans.

Be careful of getting enough airflow with this mod.

I originally tried some Gelid fans like this rated at ~20cfm. While they were certainly dead silent, the amp would shutdown pretty quick during bass heavy moments. It was definitely a thermal issue.

I now have these from silverstone rated at ~28cfm and the amp has never shut down. Slightly louder, but nowhere near the stock levels.

Nice, I have my eyes on one of these amps. 

 

Please post your impressions.

 

I read a thread that tested its output and it tested pretty close to its Behringer's RMS ratings @ 1/3 duty cycle burst testing.  Thats a lot of power in a small light box IMHO.

 

They did state it would shut off during heavy sine wave testing into 4ohms, but the amp was pulling like 20-25amps or something by that point.......  eek.gif

post #10 of 47
The Dynex fans are 31 CFM and (for all practical purposes) silent. Louder than those other two perhaps, but also with more air flow. The Dynex give you a 95% reduction fan noise (estimated wink.gif )

I've run continuous 16Hz sine waves just under the point of clipping with these fans on the iNuke 6000DSP. Seemed like it would just keep going forever.

Curious to hear your impressions of the iNuke powering the LMS-Ultra.

12V Confirmed. Wish every mod was that easy...

Haven't had a chance to push it hard, but initial impressions thus far are great! I plan to run it through the ringer at Gorilla83's GTG this weekend. I'll try to get some dialogue going with the boys to back up my subjective claims...lol

I'd say a 95% reduction is accurate. Literally night and day difference. The scientific side of me wanted to take some db measurements before and after, but in my haste I didn't take before measurements. Contemplating on ordering another one just to preform such a measurement.

I bought a Noctua for my iNuke 3000. When it's the only thing turned on in my setup, it's just barely audible if I'm standing right next to it.

Ah, you did wind up picking up the inuke. Did you get the DSP version? If the fan swap is anything like the EP4000, its literally a few minute task.

Edit - looks like you're already done. Put that thing to use!

Yeah, I got the DSP version in case I can talk the wife into letting me keep it. If so, I will use it to power my subs until I get my Clone repaired, then I'll use the iNuke for my mains.

The fan mod was super easy. I wish it was plug and play, but I had to end up splicing them in. No biggie, just would have been cleaner, ya know.

Yeeeeah man... 45 day "no hassle" return policy. I say we have fun and beat the livin $hit out of it. If it fails I better not get any hassle when I return it. If it makes it out alive I'm hoping it will earn a lil respect in the process...

I think my LMS-U's had it tapping out last night, but I'm going to need a second opinion on that. We'll find out for sure on Saturday!

Cool bro! Let us know what you think of it vs. the clone! smile.gif

Just for the Science of it... I ordered another iNuke to compare the stock fans. Notable difference for sure.



In the process of fixing my Clone, to which both of these will be sent back. Just not enough power for the LMS-U. On the flip side, there is 0 chance of ever getting the LMS-U in trouble and destroying your basket/cone from over excursion.

How do you wire these? The old fan has 2 wires and the Dynex has 3 wires.
post #19 of 47
Just hook it up with the red/black wires. The yellow wire allows the device to control the fans RPM. You don't need/can't use the yellow wire with the iNuke amps.

Ok thanks.

Austin, My iNuke DSP 6000 didn't seem nearly as loud as yours did stock. Do you remember what fans your iNuke 6000 had in it stock? Mine were NMB-MAT. I wonder if Behringer wisened up and went with a quieter fan at some point since yours and mine were manufactured.

I don't know but my nu4-6k is not very loud. It's not super super quiet and honestly could use a still quieter fan but it's no where near as loud as any of my stock Europower amps or either fans I have for the CV5k.

It can be done without the need for splicing if you take an extra couple of minutes.
You can pull the crimped wires out of the connector. Insert the new wires (stripped) through the holes in the connector, bend them around the outside and then plug it back in. Voila.

The friction from the pins makes a very good connection. I tugged on mine to the point where they unplugged and the wires never pulled out or lost connection.

I will take pictures when I mod the next one.

Jpmst3,

You don't need to pull the wires out of the connector. You can slide off the entire white connector and expose the two bare metal prongs, then slide on the new connector and completely replace the old with no splice, and no hassle. I've done this to four inukes now. A 1000, two 3000s, and a 6000. In each instance the whole connector slides off. I have pictures in my link a couple posts back.

I know, I did unplug the connectors, but I also re-used the original connectors with no need for new ones. The just pull out the old wires (with pin female pin receptors attached), push the new stripped wires from the new fan into the connector and fold them back over the outside of the connector, plug the connectors back in and voila.

I did not do any splicing either. Original connector, no cutting wires, no splicing, easy as pie.

I'll take pictures so others can follow next time, 5 minutes of the easiest mod ever.

Hi jpmst3,

I will assume that your replacement fan didn't come with a connector on it, right?

I have some fans here without a connector and I am thinking I will try your method on my 3000DSP due to the replacement fan's connector not seating as well as I would like. I look forward to the pictures and thank you for sharing your experience...smile.gif

You can buy a Pin Removal tool for R and R of electronic connectors in all sizes from a Hot Rod computer parts supplier like Frozen CPU - http://www.frozencpu.com/cat/l3/g12/c133/s257/list/p1/Accessories-PC_Tools-Crimping_Pin_Removal-Page1.html
They also carry fan extension and adapter cables.

Joe,

I follow now - I was thinking why would you reuse the original connector and risk messing it up in the swap, in case you needed to swap back to stock fans? --- but if your replacment fan didn't come with a similar connector - you'd have to use the original.

I was purposeful in selecting replacement fans with a compatible connectors. Any of the PC 12 volt three pin fan header fans should slide on and work perfectly - similar to the stock fan connector - but just not utilizing the (typically yellow) rpm tach wire. I've used several different fans on three different models of iNuke so far and that standard 3 pin header will work because it is a standard size and fits at least the 1000, 3000, and 6000. The four pin connector won't work on the 6000 because two wouldn't fit without further modification. Nor would the molex type connector work. I know you know this - just passing on the info for others who maybe considering the mod.

Newegg or other computer stores are good places to shop for quiet PC fans.

Criteria I used:
3 pin power connector header
80mm
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007998%20600035673%20600035580&IsNodeId=1&bop=And&Pagesize=50&Page=1

I'm glad you got the original OEM connector to work with your fan, I hope it works for all who try, but I suspect that it could lead to frustrations if the stock connector got mangled in the attempt, and if you have a compatible connector from the get go - it makes an easy mod even easier. wink.gif

How much airflow is your modded fan blowing? I'm wondering if I have sufficient airflow being that I have to put my face immeidately up to the front grill with the modded fans to feel anything at all at idle, and my stock 6000 fans I could feel on my face from 3-4 feet away at idle. That's a huge difference in CFM. eek.gif
post #30 of 47
I actually picked up a 6000 non dsp as well, and have modded it with a pair of Noctua fans. It is not enough airflow and the amp cycles every 20min or so.

My original 6000dsp with the silverstone fans blows much more than the noctuas - I can hear and feel it from a foot or two away. The Noctua fans are dead quiet and not felt much unless right against it. I may try one of each fan per unit to see if they keep each cool enough.
