Amp Cooling Fans?

[PuZo 10+ year member]

Since I'll be running my DLS A6 at 1 ohms, its gonna get really hot. I see that there are terminal connections for a fan, where would I buy one? Would I just place it ontop of the amp? Is it necessary? Thanks

in the manual for that amp it says that the fan terminal is operated by the temperature of the amp. meaning it will only come on when necessary and the speed of the fan is controlled by the temp of the amp. the only thing you have to make sure is not to exceed the maximum amperage of the fan terminal which is .5 amps. i myself would rather use that then a switch.

So what type of fan/cooling device do I look for?

go to your local radio shack and tell them you need a couple of 12v fans that won't draw over .5amps total they should be able to help you

I dunno how the radio shacks in kansas are, but up here, they dont know anything. I went there to get some rca's for my home audio and I asked them what type of rca I should use, and they were like //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

good point. try a good computer parts store then someone who actually knows how to build a pc not just sell prebuilt ones. after doing some thinking you could always connect a relay to the wires on the amp and have the relay turn on the fans and fuse it to make sure it doesn't over pull.... but just to make sure i'd check with dls. http://www.dls.se/econtent/111

So any 12v and 0.5a fan should work? Can i connect say 3 of them? Would any of the numbers change?

 

[Horsemanwill 10+ year member]

the more you add the more the amperage will build

So if I add 2, the max that each fan can be is .25?

What about this one

Input Current 0,12 A

That means I can use 4 of these fans? Would I just strip the connection and plug it into the amp?

 

[Horsemanwill 10+ year member]

those should work depending on how your amp is mounted you don't really need alot of fans. all you really need to do is get air flowing across the heat sinks.

 

[PuZo 10+ year member]

Wait, is this inside the amp or on the outside?

 

[Horsemanwill 10+ year member]

teh fans will be on the outside of the amp. like the manual stated just point it towards the amplifier's cooling ribs aka the heat sinks.

Okay, I was thinking of getting 2 of these

Also, do I need to ground the fan? Also what size fuse, since these wires are like 24 awg, what should I do, re-wire/re-solder to something a bit bigger like 16 gauge?

 

[Horsemanwill 10+ year member]

on page 4 of the manual i posted for you it shows me a pos and neg from your "fan terminal" so no u shouldn't need a ground and as for the fuse that's if you go with the relay way in which i said you should contact dls first which was the second link i posted for you to make sure it can be done.

okay, I think I'll leave it the way DLS said, let the amp decide when to turn it on, so I would just simply connect both wires into the amp, can I connect both fans to a central neg/pos line and then connect that to it. If I use a bigger gauge, will it have any effect on anything?

Ie connect both neg/pos of both fans(say 24awg) to 1 neg/pos wire(16awg) and connect that to the amp? The manual says a maximum of .5 amps. If I use 2 fans that are .25A each, then am I fine or cutting it close?
