How hot does your receiver get?

I just put my home cinema setup together this weekend and I'm a little worried about home hot my Marantz SR7300 receiver is getting.

It is open at the front an back with about 4 inches above it before the next shelf on my stand.

The unit itself gets hot, enough to make the bottom of the shelf above it feel warm.

As a comparison, my Toshiba 520E DVD player gets quite warm but the receiver is about 40% hotter again I would estimate.

I'm driving 5 B&W 600 series speakers from it and a sub, not pushing the volume or anything.

Is this normal or should I be worried?

Thanks

hi daneel
it is normal for receivers to get warm when driven .The harder you drive the hotter it will get .I read elsewhere that somebodys sony amp got so hot when driven hard he could hardly touch it.you seem to have plenty of space round your receiver so i should'nt worry.
ps where did you get your amp from .Hoping mine will be despatched after xmas.

Got mine from Home Cinema Heaven for £530.

http://www.homecinemaheaven.com/

They had a black one in stock and I am impatient so I ordered it. They are an authorised dealer, not sure if unbeatable is, and that's the only place I saw it cheaper.

It is working well for me although I think perhaps I went over the top for my needs, all those inputs on the back and i'm only using a few.

BTW the Marantz Europe site says it's 6 x 110W but it's 6 x 105W. Also it's not as big as the measurements suggest, it's about 425mm deep with the front nobs and rear inputs extending it to about 480mm

I just checked the temp again after watching a movie, it really does get very hot, I can touch no problem but I think it must be about 70C. All this heating up and cooling down can't be good for it.

Come on guys! Run your receiver for a couple of hours, run your hand over the top of it and post how hot it feels!

I find there are 2 patches in particular that get hotest.

My Sony STR-VA555ES is only just warm to the touch after a couple of hours of use when not really driven hard (around -65db).

well i have had my denon a1se running pretty much all day today and its not so hot that you can't put your hand over, but its notably hotter towards the centre at the front of the amp. the sehlf above (approx 3-4")does get warm but it doesn't worry me. saying that, i did cook my first 1se by puttin my dvd player on top and denon kindly replaced it for me and adviced that i didn't stack any equipment on top of it.:eek:

I had a Denon AVR3300 before i bought the AVC A11SR, and the 3300 got really hot and it even had a fan. I would say it got so hot i could'nt keep touching it for more than a few seconds. That is normal and it worked fine the time i had it.
My A11SR does'nt get near as hot, only slightly hotter than my hand.
This is using the same speakers on both amps, B&W 6XX s2.

hi Daneel,

When I first bought my receiver I stacked my VCR and DVD player
on top of it and the receiver really went hot. I mean really hot
that I can't hold it for a couple of seconds. After about 4 days
the receiver gave-in by not producing any sound on the main
speakers. I reset the unit and everything worked well though. After this experience, I decided to removed my VCR and DVD
player on top of the receiver. Now the receiver does not get hot
anymore. It feels warm after hours of running but only up to that
point.

I know this is a bit off-thread, but can anyone think of a good reason why I could not use by Denon AVR1602 on its side, still leaving the 'old top' side with lots of space to 'breath'.

I want to do this for two reaons. First, it solves a short interconnect problem. Second it looks neater.

PS The prompt to do this was clearing space for the Xmas tree!!

PPS Merry Christmas everyone. Having just watched Chicken Run, I'm escaping before having yet more nosh. :D

I have a Yamaha RXV630RDS and I have had it on now for over 4 hours at -55dB. It is very slightly hotter than it is when not on. But, I did notice last week that it got VERY hot. This was after about 40 minutes at -5dB :) I could only touch it for about 2 seconds before it started to hurt my hand.

Ditton15, there's no reason for your amp not to function on it's side BUT the components within were designed for horizontal use. I've an 1802 which I wouldn't use vertical due to it's larger heatsink but your 1602 is decidedly smaller so may well be OK.

It'll be built solidly but I can only leave it up to your judgment as to whether you feel the heatsink in particular is attached securely enough.

Not a definitive answer I'm afraid, but lets you know what factors you should consider.

They weren´t designed to placed on their sides. Heat rises, flipping it on its side means you would stop the heat escaping efficiently. I wouldn´t advise it.

I have a Onkyo TX-NR3009 and its getting very hot, so that I have problems with all my equipment in that cabinet.

I also have problems with the HDMI board.

This Topic is very interesting for me too and I really like to hear about the folowing receivers too.

I'm looking for a new receiver that will sound in the smae leake as this Onkyo.
I also need 4K with HDR, so the choice is narrow.
Pioneer SC-LX90 doen't sound completely natural, but I've heared it doen't get as warm as many others do.
Yamaha is also a bit warm sounding, so it comes up to the Denon AVR-X7200WA that cost a bit more as a Onkyo NR3030 that wont be my receiver, because the lack of 4K HDR and will probably be to hot also, and there is the Marantz SR7010.
The receiver is light weight compared to my Onkyo, and I'm afraid I will hear this and miss the power.

This thread is older than my grandson.

Some receivers get hot because of the environment they are kept in. They simply don't have the room to breathe. My Denon 6200 runs very cool, as did my old 2310 even though it is kept in a cabinet. To the sides it has 100mm clearance, above to the shelf on which the player sits is another 180mm clearance. A sliding door which is left open during operation also aids excellent cooling.

Most modern Av Receivers don't run hot at all.

I have the Anthem MRX-1120 and it runs mildly warm and sounds as good as a mid to high end Hi Fi Pre/Power Combo. Simply Lovely. :cool:

My Onkyo 805 finally died last night. Lovely amp, I'll really miss it, but the HDMI board, I think, has melted. It got ridiculously hot; it was actually possible to burn yourself on it and I actually made an additional fan, from a PC fan, to sit at the back of the rack to push the air out. I've just ordered a Pioneer LX89 to replace it. Hopefully I can retire the fan.

Both my processor and power amp run pretty hot. If left on for a couple of hours, my living room becomes noticeably hotter than the rest of the house.

I wouldn't say they get too hot to touch, but they are certainly hot. Probably similar as the outside of a electric kettle, its warm enough to tell you that the water has boiled but not burn your hand.

You have to remember that a power amp is using a lot of power and they are not very efficient about it, so if you think that if its a 100w power amp for each channels, your talking 700w of power being used, a lot of that being turned into heat.

I would suggest the 805 was faulty, maybe the power supply regulator had failed and was supplying too much voltage to the HDMI board.

The Pioneer should be fine, being class D.
It would be worth measuring the temperature in your cabinet though.

An ambient air temperature in the Cabinet above 30 deg C will start to shorten the life of components considerably.

Onkyo has a long history of HDMI board issues, so it might not have been the heat that killed it.

The 805 in particular was known to have an HDMI fault, I'm just amazed it lasted as long as it did :D It's an open cabinet with lots of air around it, so I'm not too worried about the new one.
