My girlfriend's playing a DVD quietly, the room's only 15 degrees instead of 25 last night, the amp's sitting at 25 degrees today.

The SR-508 has F:x so no fan. There's a number on the left that's usually 000 but sometimes changes to 001 or something, do you know what that is?

I have 10cm on each side of the receiver, but it's enclosed, with a 140mm fan in the back which should move a fair bit of air through. Without the fan it gets much hotter to touch. I have Wharfdale Vardus speakers, a 5.1 system. I run the amp at 1/2 power (40/80) during movies.

I think I'll get a 140mm or 200mm computer fan, put rubber feet on it, and wire the fans all to my variable voltage power supply. Even with a little case and connectors it'll only cost $40 or so, and it may extend the life of the amp. I have a power saving thingy that turns the power completely off when there's no power draw, so it'll turn off when unused anyway.

Thanks for the thoughts and help :)

ADBNZ:On the other hand, high temperatures are never ideal and exactly how long it will continue to operate at these temperatures is another question. As long as it's longer than the warranty period then Onkyo's design teams have done their job,


Hang on, let me get this right...
As long as the receiver lasts longer than 12 months (on a TX-NR515) then Onkyo's design team have done their job?

Pass.

I finally got around to doing something about this today. I put a 140mm fan on top of the Onkyo, a low noise low volume one. I have it set up to draw air through the amp, though there is a 3mm gap between the fan and the amp so it might not be working quite like that. The fan points straight up, 8cm above it there's a shelf. Behind the amp, down low, there's the extractor fan. The temperature sat at 50 degrees during a 5.1 DVD of Star Trek, with the amp mostly running at about 55/80 volume. The room temp was around 22 degrees.

Once the PS3 and TV were turned off it dropped down to 46 degrees.

I'm happy enough with those temperatures. If I decide I want to drop the temp a little more (as a challenge more than anything) I'll make some kind of funnel to point the hot air toward the exhaust fan. If I really get bored I'll cut a hole in the bottom of the enclosure and try to get it to pull cool air in the bottom, through the amp, out the top, then out the back of the enclosure. I don't think I care that much though, it's lasted fine for a couple of years, so I'll probably just use it until it fails or until I want something better.
