The fan will run slower with 5V. Whether that will provide sufficient air movement to give the cooling you need, I don't know.

Not AFAIK. You can cut the end of a USB cable and the end off the Noctua mini-Molex cable and connect the red and black wires from the USB cable to the Noctua. If you connect them the wrong way around the fan won't run, so be sure to test it before you finalise the connections.

Personally, I think a 12V 2A 'wall wart' power supply, which will run 2 fans, is the better way to do it.

I'm not sure the Noctua will even start spinning with only 5V. I'll have to research that. I have found a 5V Thermaltake 120mm fan with a USB connection cable. A bit noisier than the Noctua though.

The wall wart method would still require cutting and splicing cables, correct?

Don't all of these fans exhaust upwards? Doesn't that just trap the hot air above the 80.3? That is why I like the one that I do, it exhausts to the rear, away from other components.

The Noctua will spin but more slowly. Check the airflow on the USB fan to make sure it is enough. Yes, the wall wart requires cutting and splicing cables. I used some solder and some heatshrink tubing but a simple tape join would be fine with these very low voltages.

It depends what is above the unit of course. If there is a tiny gap between the top of the fan and the housing of the unit itself, then yes. If there is a gap more like the Onkyo recommended gap of 8 inches, then no. But you are correct that the warm expelled air needs to have somewhere to go.

Four inches seems to be enough for me.

Yes, I'd expect so. So long as there is room for the fans to push the warm air away and it isn't 'pooling' on top of the unit, it will be OK.

I agree bi-aming isn't worth the trouble. Use your 80.3 with wide and high speakers and Audyssey DSX in a 9.1 set up, you will be amazed at the results. Any perceived improvements from bi-amping will not be noticed.

Agreed. And for people who don't use Wides, they might want to try Dolby PLIIz for the height channels too as this doesn't reduce the SPL in the surrounds, nor does it decorrelate them. Some people prefer DSX, others, me included, prefer PLIIz.

Bi-amping done properly of course, with external crossovers, does bring some significant benefits and is often one of the reasons why 'active' speakers sound so good for their size etc. But yeah, doing it with passive crossovers in the speakers, the Onkyo way, is pointless.

I always run external cooling fans on my Onkyo/Integra receivers and pros at below nominal voltage. I use old cell phone chargers and feed 5-9v into 12v computer fans, receivers get a bank of 4 serially linked 60mm, processors get 2 fans over the warmest area, usually the HDMI board.

At below nominal fans run quieter and last a lot longer.

Update: DHC-80.3 on the rack, King Cobras analag and XLR interconns (and stereo) too, Salamander Archetype rack is awesome. Tons of work with sticky labels and cable management, while at it put MIT AVT1 cables all around the Escient 1200DVD changers, after all Marvell Qdeo should make these shine. Secondary monitor up too, thx God this unit allows dual displays unlike the DHC-9.9, now i can enjoy SACD and read titles without the PJ.

I use one 120mm usb powered fan over the HDMI board and it seems to perform well, my 5508 runs just warm to the touch.

Isn't the benefit of using the 80.3's USB port to power the fan (rather than the wall wart method) that you don't have to worry about either leaving the fan constantly on or turning it on and off manually? It would be on only when the 80.3 is on.

My USB in the front and back are hot regardless if my receiver is on standby or not, so the fan will always be on. I have Onkyo 3009 so it maybe different but highly unlikely. Best to use a smart power bar if you want the fan to switch off with the unit.

Theresa, does your USB powered fan run constantly when the 5508 is on standby? Does the fan run constantly when the 5508 is powered off?

The DHC-80.3 is on a small back order.
Mine has been ordered since 1-13-2012.
(Per my A/V Dealer)
I also a few days ago ordered the Integra DBS-50.3 Blu-ray player.

I just plugged a usb drive into the front of my 80.3 when off and it lit up, so it must be hot all the time.

Thanks very much N8Dogg. That's what I wanted to know. It seems that I can't rely on the 80.3's USB port if I want to have the fan on only when the 80.3 is on then.

Just checking - the 80.3 was powered off and not on standby, correct?

Onkyo seem to have changed the behaviour of the USB port on the rear. It used to power up and off with the unit (standy mode not full power off) but now it seems to no longer do that.

Got my replacement 80.3 and now have 2 working HDMI outs. It's nice to have and OSD. Now I'm greedy and wish the OSD was on both outs. Kept hitting the home button thinking something was wrong while watching a movie on the PJ.

Just amazed at what XT32 does. Everything is just seamless and smooth. Though I run full range mains and surrounds XT32 chose to cross everything over at 40Hz. Sounds great even in 2 channel but sometimes I'd like to just run things in stereo at full range. Is there a way to save another profile with no crossover and disable Audyssey. Or do I need to manually change the speaker configuration to full range every time? I also assume that if I change the settings then change them back then the Audyssey curves will still be there, correct?

Thanks

Andy

Keith, just want to make sure I understand you. . .

On a new 80.3 unit, I should expect the USB port to provide power at all times the unit is either ON or in STANDBY mode, but the USB port will provide no power when the 80.3 is in full power OFF mode.

Is that correct?

So the OSD is not on both HDMI outputs? That's disturbing as 2 HDMI outs is my primary reason for getting a new processor. (I have an Anthem Statement D2 presently with only one HDMI out)

Both are active at all times but the OSD is only Active on one as far as I can tell (hope I'm wrong). It's no big deal if the unit is in view (processors front display is prety clear) but if you have it in a cabinet well...

I also changed from D2 (to Onkyo 5009). One of primary reasons was for two hdmi outs so I would not need to turn pj on for music and setup. Needless to say I was very disappointed that osd was not available on both outputs. also very disappointed no trigger on main on 5009.

would love to see osd issue changed with firmware update. I doubt that would happen with Onkyo.

TBH I have never tried it in full off mode. The USB port used to power on and off with the unit (standby mode) but now apparently it is powered all the time the unit is on or in standby. I would expect it to be powered off if the unit was powered off (can't see how it could be otherwise).

If you do not mind sharing with us that have them on (Back-Order) what is your source of info. on the Date ?

Just trying to see when I can expect my New Gear to be installed.

I just read the review in Sound and Vision. I have a DHC 80.3 on order (backordered, of course). The only thing that disturbs me in the review of the 80.3 is that the "trim level" is limited to center channel and Sub1 and Sub2 only. Due to huge differences in the way movies and concerts are mixed down, not to mention DTS MA and Dolby THD differences, I use the "on the fly" level adjustments on my Integra 9.8 preamp all the time, especially on the rear channels. I can't believe that Integra would have limited that adjustment to just center and 2 subs. Can someone verify as to whether this is true or not?
Thanks!
