fans not a working

leftwinger57

Hi guys , been a while because I've had no complaints other than heat from my avr.Right now I have a Yamaha RX-V665 W/ kLIPSCH SET #500 W/ 8IN pwrd sub and has only clipped a couple of times which for me is 2 to many.Asking many here you say go w/ a fan co. and I did and is whofully defeciant to do what it's asked of it. First I was told an audio fan no matter how quiet should always suck the air out not to blow dust and any crap lying around. It's made of plastic and has a speed contrller buy the output is shameful.A person w/ a breathing disorder can do better than this thing.I got from Cooler Guys .com out of Wyoming, but if they think it's a complaint they do not pick -up.This choice I made and was a very bad one.
So any others out there that don't cost a fortune and does what it's supposed to do. If I don't heae from any of you guys have a happy 4th and party long and loud..Thanks.....LW

A friend has a $1k onkyo it runs wrm so he got a boxer fan from a (computer power suppley) mouted the fan to a piece of foam and plugged the fan into a wall wort (to get 12v DC) than plugged the wall wort into the AVR's switched output AC plug .
Works great the avr is a lot cooler and a good/new fan is almost silent .
OR
if its a cabinet or has a no aur room above it gotta try something else , likr fan cool the cabinet (no fun)

I would check Newegg for fans. They have all of their fans rated. Just out of curiosity - do you know the specs on the one you bought? I've seen some that can push 40+ cfm for less than $20. Fans pretty much go from 5 to 60 cfm without getting into anything too crazy (i.e. like some $150 fans)

I would suggest larger case fans. (~200mm) They output more cfm, and do it at lower rpm's. Slower=Quieter.

Lots of fans:

one thing if you get a D/C fan you can use less the voltage and the fan will be quieter (and slower) I dont think the AC 117v ones you can do that to easily (maybe a moter controller will) also there are fans with thermostats out there .
I actually built a duct and mouted the fan but later I saw the type with the foam pad on ebay .

Could all this mean that you really need another AVR? I think you should start to consider this.

Being an electronics Journeymen, I have found that if an amp is clipping, it's time to replace. You can't comfortably use it to the level you want and the clipping due to excessive heat is mostlikely taking away the longevity and reliability of the component's inside.

Look for some deals and rearrange the placement of your AVR with a fan until you can get a new AVR.

I'm with the D-class camp for this reason.

On the other hand, I think a lot of AVRs just run hotter than most people expect. Period.

Does anyone really know what "hot" is, and what's "too hot"?

Also, the "clipping" is just as likely to be related to the fact that he's running small sats that only have recommended amplification of up to 100 wpc. Really, the best recommendation here is to go easy on the volume knob. I think his AVR is perfectly adequate for the speakers he's running.

If your AVR goes in to clipping, it has to do with a few things.

A speaker with a burned up voice coil.
No more headroom, amp maxed out.
Overheated power section.
Built-in cooling fan not working.
Lack of proper ventilation.

Just to to name a few.

Upgrade time is in order. Turning down the volume will suffice for a little while, so that statement is true.

New AVR and speakers with more power handling will fix it for good. Maybe a amp too.

I was told by a repair tech "if you cant set your hand onto of the componant indefinatly , thats to hot"
plus if you can fan cool it will last longer .
big heat=death

My point, more or less, was how do we even know the diagnosis of "clipping" is even correct (which was the reason for my quotes). People could mistake distortion for clipping, or bad recordings, or.... who knows? He's running a set of small satellites with an amp that really isn't half bad, especially for that application. I don't think that amplification is his weakest link. You just can't crank speakers with 2.5" woofers very loud.

That's a generality, but not really a good measure. I don't think you can set your hand on a tube amp for very long.

P.S. Use spell-check, please.

mdaudioguy, you would be surprised at the output of those little Klipsch's.

My bet is the sub is set too high and that is the clipping he is hearing.

The heat on the other hand is another problem all together.

How hot are we talking. Too hot to touch fry an egg hot? Or more like it just seems to hot to me hot?

Too hot to touch would make me think there is an issue with the AVR The cabinet is totally confining or the volume knob is just cranked up too high. Probably the cabinet and the volume.

Get a better cooling fan preferably an AC fan. And turn the volume down just a bit.

I've heard them. Not bad for a small room, like perhaps a bedroom. I have some sats that will easily outperform those, and mine still don't compare to larger, box speakers. They are pretty decent for HT, though. Decent quality at low to medium levels, but you're not going to get rock and roll volume out of them.

yup tubes are serious heat , I bet you could warm a small room with some of the tube amps I have seen .
I would happy to use a spell-check but I dont see one in above box .
So if there is one there please let me know ..

@20hz - I use Firefox, and it has built-in spell-check (underlines misspelled words with red, squiggly lines).

@Glowrdr - I don't see this option in FF, but I just tried IE and it was there, so it looks like we're covered either way! Don't know about the other browsers... I'll try some out later.
