im just saying that poeple are having promblems whith avr525 i think heating up and shutting off so the fan must not be set rightin the reciever.

Seriously, since these HK receivers seem to be having heat related problems wouldn't one be better off replacing the damn thing with one that doesn't have a design problem and doesn't need a fan of any kind in the first place?Political Correctness'.........defined

I ran my h/k 520 for about a year before buying my Outlaw 770 and with that said never had a heat problem. The h/k remains in the HT rig as a pre/pro only... for now that is:D

F1,
on this one I think Typo has a good point.
In a perfect world, manufacturers would build absolutely failsafe protection mechanisms into their receivers. Problem is the all-in-one-box approach inherent in receiver technology, especially with large heat generating components, which are getting larger and more powerful with each generation. With limited space, mfrs have no choice but to make compromises, and making the enclosure a lot bigger is not the practical choice. Excessive heat is potentially harmful to electronics, chips, circuit boards, cabling, the whole lot. Some receivers are definitely more prone to higher heat than others, because of the architecture of the internal components, and perhaps as you suggest they are built to a higher tolerance, but can one be sure? My Yamaha is such a receiver, and I know this to be true because it is being remarked on a lot by many owners on several different forums. One thing that makes me uncomfortable is the regularity (every 30 mins or so) with which the internal fan must come on. Why is the Yamaha so prone to high-heat? - I'm pretty sure its because the massive power supply has forced the designers to make a compromise in the heat sink architecture. I am not inclined to think my unit will fail, I do have more faith in the designers than that. But just to be on the safe side, I think its wise to have an insurance policy. I think that is what Typo is trying to convey.Polk SRT HT System

Hmmmmm...you think I'm being too hard on the boy, eh?
I'll give this all more thought after I've had some sleep as I can barely keep my eyes open right now.
Oh yeah, F1 is in China this weekend. Should be interesting!

im not saying your wrong f1nut i just feel better that i know that the extra fan is helping keeping it cool thats all.

Ok, gave this some thought.......if you're not having a problem with the receiver shutting down and the internal fan kicks on when needed, then it's operating the way it was designed to do. You don't need to add a external fan, however if it makes you feel better and since it is your gear, then by all means add the fan. I think that by doing so you're going to add some degree of noise, dust will build up quickly inside compounding the heat build up and the unit will not be operating at it's optimum temperature, therefore you're not getting the best possible sound from the unit.
I agree with most of what O'Shag alluded to concerning the design of current AVR's. It's a shame they don't put the heatsinks on the outside like he-man amps. Besides solving heat issues without the use of a fan, they would look much better.
To tell you the truth, on my he-man 2 channel rig, I like to feel the heat coming off of those massive heatsinks. Makes me feel proud of my baby! Political Correctness'.........defined

hell yaa... throw a frying pan on it and cook up some sausage;)

Dust is an amazing insulator. Ask anyone in IT. That stuff us awesome for keeping the heat in. Make sure you blow it out often, or your fans will be self defeating.Go BIG or go home!
