Maybe pull the fans to see the size and type. It might be close or the same as some other amps that have been modded. If not the same, people could better advise you on what would be a good substitute knowing what you're working with.

The fan should have a model # on the round sticker so you can look up the specs. Voltage and amperage should also be listed.

Most 2U pro amps seem to use 80x80mm 24V cooling fans. On the Parts Express page for your amp it describes the cooling system as "three temperature dependent variable speed fans." I'm not familiar with the Peavey amps, but I recently changed out the fan in my QSC RMX 850 amp with a quiet NMB Technologies fan, Part # 110SB-05W-B20-E00. It's so quiet I can barely hear it from a foot away.

Those look like 80mm fans to me, so the NMB part number in my previous post should work.

I am hope they will be quite. The two fans that are in there sound like hair dryers. It also has a small little fan up towards the front but that one is not as loud as the other ones. Got to try it out for a little while last night watching IRON MAN 3, holy crap this thing defiantly has some power a lot more than the two crown XLS 1000's bridged and this thing can get pretty low.

Yep. but you obviously haven't heard an unmodded LG clone. That puts the peavey to shame. The little fan or inserting resistors might be a good option for cutting down the loudness as well.

Word. After the CV5k and my gaggle of EP4k's, I think I'm gonna try these lightweight amps next. Probably the 7500.

Hope the fan mod works!

I won't be cutting up the wires on the fans as I have a 5 year warranty. I will pick up two ends from my local ALTEX computer supply store and install them on the new fans that way if I ever need to send the amp in for warranty work I can simply replace the fans.

That would be great if the Peavey use a standard connector that you can mate to - does it?

Sure! The Peavey has a more low-hum sounding fan setup where when I first cut it on, I almost felt like the the fan was loose inside the box. It wasn't, but that is what it sounded like. The Clones on the other hand had a more higher pitched fan sound more like that which you hear from a windows laptop. I can't really go much more into detail other than the peavey disappears a little easier under a decent level of content.

Looks to be the case here:

Ah, I thought you were talking about the SQ of the amps, not the fans

Hey Beast I don't have the part number but it is a 2 pin 10mm connector. I am going to take the fans to ALTEX and radio shack to match exactly. As soon as I find out I will let you know.

I also forgot to mention these fans are on all the time. They do get louder under heavier loads. NOT like the crown XLS 1000 where the fans kick on at a set temp.
