Alright everyone I have searched the archives and how does everyone keep their amps cool?

I currently have four amps with over 3000 Watts RMS and I want to make sure they wont overheat this summer in CA.

I am familar with computer case fans, amp fans and blowers but wanted to hear what methods/gear everyone uses.

Thanks for your input!

2 blowing, 2 sucking is what I have. Also make sure your amps heat sinks are mounted vertically.

I use a 4" bilge blower with the hose blowing across the amps. The second advantage to this is that you’re not just blowing the same hot air across the amps. My fan draws air from near cup holders in bow. Lastly this setup gives you more flexibility on where to place fan and bilge blower move more cfm than computer fans.

I use 2 of the stinger cylinder shaped fans. They are low profile and move alot of air.

That's a great idea, Brandon. I have two mounted in my only storage area under vented acrylic. Often, they are covered by bags and what not. On a hot day, the tower and interior amp will shut off. Your set up sounds like the perfect solution.

fat sac, the only issue with those bilge fans is they are loud, and have a very good potential of intriducing nosie into your system. But they do move alot of air. IMO you don't need that much.

I have used bilge fans and they work very well. I ran them off if the amp power supply and put in a small switch to turn it off when I didn't need it.

no problem with introducing noise into my system and as far as the fan being loud which it is minimal only a problem when listening at very low level with motor off and then you don't need the fan so turn it off. Also you could install a speed control to slow the fan.

I've used the bilge fan with a switch and it works great. I may look into the stinger fans on my new boat.

Dual push/pull configurations move no more air than single fans. However, side-by-side fans will displace twice the air as a single fan.

The key to efficient fan use is a shroud that forces the air across the entire heatsink surface area. A fan without a shroud circulates air around the fan but not around the amplifier.

PAC makes inexpensive 12-volt fans. You can safely run multiples of these off your radio’s turn on lead via a relay.

I can't believe no one else commented. Guess they aren't as cultured.
