Axiom Home Page Forums General Discussion Technical Questions Cooling Fan

with it being a (relatively) small fan, it shouldn't be problem running it off of one of the outlets on the back of the reciever. a fan like that is a pretty small load so you shouldn't worry about tripping the reciever. and if you do have to get a DC fan, radio shack has adapters in a multitude of voltages, so that wouldn't be a problem.

p.s.- you know you love the funky wookie!!

I have my amp and DVD player plugged into the back of my Denon. No problems at all.

Some of the fans are loud. I initially had one from Rat Shack mounted on the back of my HT cabinet and plugged in to the back of the 2805. The hum of that thing drove me nuts. Took it off.
I have seen some on e-bay and other places that are made for cooling HT gear, and are supposed to run almost silent.

John, if Tom's suggestive language didn't get you yourself too hot and you're still reading this, I'd suggest not worrying about a "precautionary" measure if your receiver isn't glowing red-hot. Fans can be noisy.

thanks for the advice guys.. i reckon i will just wait til i get the satellite, and just see how hot it runs when being on for several hours at a time.. if its not too bad, then i will just scrap the whole idea..

although, i do like the idea of getting a dedicated amp just for the fronts.. a nice monoblock might be in order.?

2 "mono"blocks?

John, take a look at the link in my sig. I'm using an 8inch silent external fan from radio shack. $12 if I recall correctly. It keeps my receiver ice cold.

I have it blowing up to suck the air out as others have already stated. The fan is extremely silent if standing up by itself but does make a small humming sound when placed on top of receiver from sucking the air so fast throiugh the vents. Unless you are really anal about or are trying to listen for it, you will barely notice it after awhile.

I listen to my movies loud so I don't even hear it except for extremely quiet scenes. Again, it is a very faint sound. I had to splice an AC cord to it (since it is made for computers or electronics I believe) and plug it into the back of the receiver so it turns on with the receiver.

My HK avr630 runs hot with the M80's. Until I ever decide to run seperate amps for the fronts, I will be sticking with this option.

Hey Shag:

Is your fan DC or AC? If DC, where is it plugged, do you have your own DC power source?

thanks a lot!!

Nice thing about stuff from Radio Shack is they have the part numbers on them. I looked it up. Here's the link for the fan I have.

Like I said before, if standing upright by itself you can't even hear it. Lying down on top of the receiver it makes a humming noise because its sucking the air out so fast.

You'll have to decide for yourself if it bothers you. I did have to splice it with a plug, also from Radio Shack, and I plug it into the back on the receiver. Reciever on fan on, receiver off fan off.

I did much the same (Radio Shack cooling fan with Radio Shack DC power supply, using receiver plug). In my case, the receiver is inside an armoire wih 1" of clearance above it. With the door closed, the inside gets really so hot that I worry about damage to the CDs stored inside, plus the possibility of damage to the furniture itself. (The armoire is Ethan Allen and costs more than my sound system combined!) So I put a fan sucking air out of the armoire itself. But the air circulation is pretty lousy, and eventually I gave up and now just leave the door open and the fan off (the fan isn't absolutely quiet and I'm really picky about noise). The way I figure it, the receiver has lasted 3 years already without failing, and if it dies from overheating tomorrow I'll just go buy a better one. Electronics will die sooner when they run hot (many degradation mechanisms in ICs are accelerated rapidly by temperature, often something like a factor of 3X per 25deg C). But I'd rather enjoy the sound on a short-lived receiver than have noise for a very long time.
