    whoa,got my 606 all wired up,and i was fiddling about with different sound settings,by the way,playing sweeny todd on the ps3 bluray player sounded fookin amazing!! and listening to Metallica-Turn the page on all channel stereo,amazing,i wanted to turn it up ssooo loud it made me smile.Anyway i was watching i am legend,playing a ps3 game,i put in transformers and turned it to bitstream,as soon as optimus started to talk.....BLINK...off she goes.
    Turned her back on,and after 30 secs,same again.Felt the top of the 606,and my god,i swear,you could cook on that surface.
    I noticed that there is no vents on the side of the unit?!?
    They know it gets hot so why didnt they vent the sides.ive got about 4cm clearance from the top of 606.
    Im going to unscrew the feet and take them off,that should give it a little more room uptop.
    Im also going to cut som of the wood away from the back shelf to try and get the air flowing a bit better.Has anyone else had this problem?

    I saw on hifi bitz website,they reckon they are 6ohm.ive knocked the setting back down to 4ohm,do reckon that might have done it?seriously,the unit was mega hot,painfull to touch.
    Just looked at website,its hifix,and they reckon on the speaker specifacations that the br1 weighs 9.5 kg!! no way,i weighed them on saturday for speaker brackets,4kg.
    So,i think maybe that they might be a bit off on the ohm as well.i havent had proper time to look into the ohm and hz yet.
    Cheers

    I remember reading about similar experiences with 605, basically do NOT take the feet off as it just makes the situation far worse.

    Anyway, the manual says 8 inches of upper clearance, but you've only got about 1.5 so it's not really surprising.

    I was wondering if products like this need to meet certain UK or european requirements? Do goods get tested/stamped for certification?

    Your not the only one who has mentioned heat as a concern. I suppose they can get away with it by saying you need 8" of clearance in the manual? It does make me reconsider. But at the price it may be worth the risk (well not if you factor in your house burning down) :rotfl:

    This may just be scare mongering or some bad experiences or may just be a design fault. Who knows.

    I had heard of lot of over heating problems about the Onkyo, but before getting my 805, I took a shelf out of my AV cabinet meaning my amp got about 11cm of head room. (Touch wood) I've never once had a problem with my amp and it's had some serious usage, and does get VERY hot. I'd definitely try and give it more room at the top, as I think that's definitely the problem.

    Ive taken the feet off,which has given me a few more cm.
    I felt underneath and it did feel quite hot on the left hand side,but nothing compared to the top.What else can i do?
    get a new stand?i cant afford it.i just hope it dosent go off when me and the missus are watching a film(she will moan and moan,about how much it cost etc..)
    IM going to try and get a little fan for the inside of the stand,and cut a bit of wood away.I knew they got hot,but SO hot it would cut out after half hour,im a bit gutted,and now,paranoid that its going to cutout when im using it.
    What can ido?:suicide:

    I re-iterate, do NOT take the feet off, it'll just make it worse.

    Only got 2/3 inches above mine and it gets no more than very warm in one area on the right, however I dO have clear air on the sides and back - also the shelf above is glass and by all accounts that conducts heat better, but it only gets mildly warm.

    I second the feet thing, the amp draws in cool air through the bottom, if you close that off then it will get amp-wreckingly bad.

    Indeed. I have my centre channel on the shelf immediately above mine but since there was so much space behind the speaker I just chopped out a square of space above the Onkyo. So the front few inches of the Onkyo only have about 0.5" clearance (!!) but everything behind that (back-right definitely gets the hottest) has the full 8" and had no problems so far :smashin:

    o.k then, feet back on.ive got to cut some of the wood away at the back so the air has somewhere to go because its all sealed off at the back.so my 606 is hanging out of my stand untill that wood gets sorted,nice.

    Just got it today and bought a oaur of Celestion floorstands to start with, very nice.
    First, the main use is for HDMI audio with the V+ box and the PC (both work fine with direct input to the TV (Panasonic 42" plasma).
    The PC works fine directly into the TV under Windows and Linux but not through the 606 (in fact Windows doesn't even find the HDMI audio output).
    I would use the optical connection instead but haven't managed to ocnfigure that yet.
    The other thing - heat! I have free space above the amp nad lots of space all round, it sits on a glass shelf at the top of the stand but gets too hot to touch. Is this because I've only got 2 speakers hooked up so far or is it a known issue?
    :lease:

    The Onkyo only passes standard ED/HD resolutions (480p/576p/720p/1080i/p) over HDMI so if you're trying to send it a funny plasma resolution like 1024x1024 etc. then it won't work.

    If anything it would run cooler the less speakers that are connected to it. As long as it has plenty of space above and around it (6"+) then you'll be fine as they will get hot (especially the back-right area). Also do NOT take the feet off.

    There has been a lot of talk about the heat generated by the 606,and the consensus is to make sure you have plenty of clearance above, mine has about 10" and gets quite warm also leave the feet on it so as to get a flow of air though it.

    Err.. the video is fine and I am defintiely leaving the feet on!
    I've jsut put a low speed (very low noise) PC fan on top of the amp (adding rubber feet) and the case temperature drops to near ambient. This will increase the life of the amp quite a bit.

    Trollslayer is the fan sucking or blowing? will it fit in a 30mm space?

    Cheers

    I don't think it's acceptable that we have to add our own fan for a £400 part! I wonder why they didn't do it themselves? You can get some very quiet fans (like a Scythe Slipstream).

    I'd much rather the option of a silent unit with plenty of space round it. It's easy to add a fan but hard to take one away.

    I installed 3 120mm fans at the back of my tv cabinet to aid cooling, ordered a 5.25 external drive caddy and inserted a fan controller. Cost about 50 quid for all the bits but the benefits were endless. No more hot 606 for me.
