Hi All,

I see there is a thread for the EP model amps from Behringer, namely the EP2500 and 1500.

I just purchased one of the new model amps, the EPX2000, which is supposedly a lighter weight, quieter amplifier. Sadly it's still rather noisy.

I am wondering if anyone could advise me on modifying the fan on this model.

Would it be the same kind of process as with the older EP2500 amps?

I am in Australia. Does anyone know of the best fan to buy locally in Australia?

Would be greatly appreciated.

Cheers,

Scottie

Nice one. Just opened it up, and there's 2 fans, both 24Volts.

I ordered 3 fans from Newark last night, only to realise later that they won't ship until January 14th 2010 :( So I'm going to cancel that order and try somewhere else!

I saw your post...

One thing I did when I screwed my lid back on after checking what fans I had..... was that I accidentally screwed the top on so that the metal lip was on the outside of the back of the chassis, and kinda bent the chassis a little... turned it on and it made a strange noise..

so I undid it and realized what I had done.. then repositioned the top lid properly so that the lip at the back sat inside the chassis. I'm unsure if the design is the same on the 2500.. but maybe when you screwed it all back together you did the same thing I did... which could be putting pressure on the fan causing it to not work?

hi Mika,

Well I have merely switched the amp on. It's not connected to any speakers. But from what I can hear, they're on from startup, and stay on, at a constant speed, blowing into the unit from the back. Only the right fan (looking from the front) blows through the amp into a piece of cloth/material before passing the air out the front. The left fan blows freely into the amp to cool the other components.

I'll take a photo once the new fans arrive :)

Interesting. I did see that too. All I can say is what I have heard so far. I have left the unit on for about 2 - 3 minutes, and the whirring noise stayed constant, and neither got louder, or softer. I can only imagine it would get louder as the load increased?

Heya,

It all went great. I actually ended up getting a local electronics guy replace the fans for me as I didn't feel confident getting in and doing it myself.

The fans I got are the ones everyone were suggesting to get. They are essentially silent. I have them in my dedicated light/sound controlled HT room and I cannot hear a thing.

The amp has worked great since the upgrade. Plenty of power for my needs. Never really pushed it past its limits. In fact I have to keep the 0.1 channel down a little as it can be a little over the top!

I have had the amp randomly switch off a couple of times in 4 years. But that hasn't really bothered me.

Hope this helps,

Scott

To be honest I have never had it shut off from pushing it hard. The only times it has shut off have been completely random and almost always at only normal or low volume. It's only happened a handful of times in the 4-5 years I have had the amp.

I will see if I can find the spare fan I have so I can confirm which one it is. But I am 99% certain it's the SAME fan as used in other mods of the older Behringer amps :)
