Do all receivers run hot?

post #1 of 28
Thread Starter 
I was very close to picking up some cheap bookshelf speakers to use with a 2004ish 6.1 1000w onkyo receiver but after using it for a day or two I realized this thing was running very hot with only two tiny surround sound speakers running 2.1. The receiver is on top of a table with all vents free to breathe, not stuffed into a stupid death cubby. It's basically a space heater which isn't what I want in the summer.... It should be hitting 100+ where I live in the next month or so.

Is this normal? Do most receivers run really hot?

What's the exact model number? I'd check around the interwebs to see if anyone has had similar issues. However, some recievers/amps do run quite hot. I have an older power amp that I run my bookshelves with and it's basically one big heatsink. It'll heat up my room after an hour or so of listening.

Its an Onkyo HTR-520.

Well, looks like there's hardly anything regarding overheating problems from what I could find. It's probably fine but you could open it up to see if there's any internal fans that aren't operational.

One thing to check though before doing anything is the speaker wire connection. Make sure there are no stray copper strands touching the amp or otherwise untidily connected.

The wires are all tidy, I already went through that. Would the gauge of the wire have anything to do with the heat? I didn't think so because this thing heats up the room even if the headphone jack is being used.

Ill just give up on it. I was just wondering If other receivers were the same way in case I wanted to go out and drop $500 on a newer receiver + speakers.

Both my onkyos are too hot to touch after 10 minutes of being on.

I have an Onkyo, bought in the last 4 months, with a 3 year warantee, and I can feel the heat coming out the top.

But my friends older Sony feels the same, so I shouldn't worry about it.

As far as I can tell, there are no fans inside mine, and I always wondered would it be worth putting a low speed one in, but mines relatively near a window anyway and there is always a breeze in my room smile.gif

Guage shouldn't have anything to do with it. Sounds like it's normal operation.

Mine is definitely fan-less but even if there was a fan the same frightening amount of heat is being dumped into the room.

frown.gif I guess its back to the junky logitech speakers that don't give off any heat.

Even my Yamaha receiver does run a bit warm. When you look the inside of any receiver, you see the large heatsink and that tells you something. redface.gif
