Well, I did the fan mod to my EP4000 amplifier. While trying to remove the fan connector the whole connector on the circuit board came off. It was glued together! I managed to save the day by soldering the fan leads directly to the pins sticking up. This was not easy as I have a severe tremor, but it worked! Looking at the glass as half full I have to say I saved the day rather than it was a tragedy narrowly averted.
Someone on Home Theater Shack just told me that the connector comes off that way and will fit back on if I need to send it in. Its operating with a 19cfm fan that is 30db quieter than the one that's stock. Its totally quiet now and I don't have any source that I want to listen to at very high volumes, just a 6db boost at 18Hz, but there's also a HP of 48db/octave that is at the same frequency.

Theresa your warranty is done. They can tell if the connector has been taken off. I have a friend that works for a Behringer repair center near Toronto and it's one of the first things they check for now. They can tell just from the condition of your amp what your using it for. Your not likely going to have any problems anyways. He said they very rarely get any ep2500/4000's in for repair and if they do it's usually just blown caps (which you can repair yourself) All my 8 run strong and I've never had an issue. Our HT's don't put much stress on them like a live show would. They usually are just loafing around, not doing much.
