Does anyone use coolers to cool down their system (receiver, amp, etc.)? I am thinking of getting one. The laptop coolers are cheap ($15) - would they work or do I need like 10 to cool down my receiver?

    I picked up two fans with a thermostatic switch for my amp on ebay relatively cheap. I'll get you the info later when I get home. They work well and are literally silent.

    This units are excellent, but a little spendy. They run the fans at 1/2 speed, so they are very quiet. You can use the supplied thermal switches, or bypass them for constant operation.

    I used the "Cool-It II" on my power amp some time ago. It worked very well.

    I'll post it as soon as I get to the house. Seems they were around $30.

    Steveinaz, I looked at the site some time ago. Their coolers seem great, but they are kind of expensive. I don't feel like spending over $100 on a fan.

    Sometimes they can be found cheaper thru other distributors. I had an "open" rack, and the Active Thermal unit was the only one I could find that was quiet enough.

    I did try a DIY project involving 2 Vantech Stealth computer fans, I chose the quietest model, but they were still too noisy; of course if your rack is closed they would work.

    If your gear is running hotter than specified by the designer/manufacturer then by all means use a method of cooling.

    Certain class A amps (for example) sound their best when the output trannys reach a certain optimal temperature. Many of the good designs that put out heat are designed that way and the parts used can handle the heat cycle for a very long time.

    It's not always best to cool everything. Certainly if you have a specific situation like an enclosed space or you are running extremely inefficient speakers or constantly running at a very high volume (ie: on the verge of overdriving your amp) then external cooling makes sense.

    Generally speaking in a computer you want your chip to run cool and in audio if it's running hot (generally speaking) it's designed that way.

    Many typical A and A/B amp designs are intended to run with a little heat and in many cases yous sound can suffer if you try and cool things down too much.

    YMMV as well as your individual situation.

    You haven't even explained your gear, how you run it, where it's placed and why you feel it needs to be cooler.

    Looks kind of like two cheap computer fans with foam on the bottom with a fan speed switch and running off a 12v wall wart? Although I suppose the auto-shut off feature and complete kit is handy at the pricepoint. Whatever works!

    I grabbed a rack mount cooler that uses three large fans and runs off 120v and figured it'd be perfect to place on top of an amplifier. I got it home and plugged the sucker in and it cooled down the amp alright, but it also sounded like someone was vacuuming in my room. Perfect for a server in a locked room, but not for home audio.
