Onkyo, How to connect Onkyo 616 Cooling Fan to a internal 12v supply. Part 2

[@fixtillbroke]

I had no problem switching to the "writing" 12 v output. However, if my 616 is plugged into AC power, the fan is now constantly on. I find it too noisy as well. If I unplug from AC, of course I shut down the stand by feature, and can't use the remote to power up on demand. My questions are, how do I find out why the fan outlet wasn't working or did my 616 never get hot enough to kick in the cooling fan, that I personally find too loud. I've watched a couple of hacks to install a speed controller to the circuit but it's shown in at least three different configurations. Recommendations?

[@hudsonrobert49]

I have found that switching the HDMI through OFF then it doesn't stay on when switched off hope this works for you.

@@hudsonrobert49 I must tell you, I just got this from a guy who was going wireless and small. He sold it to me for $20 because he couldn't restart it after boxing it up a few months ago. I don't know how I got it going other than I disconnected the black HDMI cord, swapped it around for a tighter fit on the board it plugs into, kept pushing buttons till it finally switched on. This was before I opened the remote, cleaned the contact button insert and wiped down and scrubbed the 'board' and battery contacts. Needless to say, I have not connected this to a video screen, and therefore have no idea about the set up menu or the types of customization I can put in place. So Rob, is this where you go to first shut off the HDMI like you say in your response? I don't see a remote control button that is labeled in a way that suggests it could shut down that 12volt power. I do have a PDF of the manual but I'm too lazy to scroll through it this morning. Someday though. Thanks man.

Ended up buying a variable speed regulator for the fan. I have some pics on how I installed it.

@@fixtillbroke yes the fan does spin quick, you will have to put a link so I can see how you did it please thank you for your reply

[@fixtillbroke]

KZbin won't let me load a slide show of my phone pictures​, I could post to another audio site that you follow or should I just take a phone video and post that? I wouldn't be able to show all the details but I know you would be able to get the idea okay. I'm having no problems starting and stopping the 616 any more since keeping standby on and the temperature very consistent with the fan, which now I don't hear at all.

[@Nick-ology]

I wanted to add my thanks for your very helpful video. I just encountered a scary "auto shutdown" of my Onkyo 616 from what I could tell as overheating with no fan spinning. I'm not sure what caused the fan to no longer work under heat load as it used to, but now I have a permanent fix. If the fan even gets too loud or a bearing goes, I'll probably replace with a comparable Noctua PC case fan in the future. Thank you again, the connector was exactly the same and I was able to slide the casing off without having to unplug everything from the receiver... somehow.

[@hudsonrobert49]

you are welcome I am glad it worked for you

[@mikep95133]

I moved the fan connector on my NR626 to the same place you did Robert. But the 12v connector was smaller. The pin spacing was the same so I just broke the tiny weak walls off of the connector. The fan connector just barely fit. It spins very quietly. The 626 runs stone cold now !! Not any heat to be found around the outside of the receiver !! Thanks for the tip Robert !!

[@mikep95133]

Thanks for the heart Robert. Well over a year later and my NR626 is still running stone cold !!

[@hudsonrobert49]

@@mikep95133 I am glad it's still keeping cool, Mine is still working fine.

[@izzy76slo]

I Just did it on my 626. Fan works, let's hope no blackouts for my receiver anymore :D Thanx to both of you :)

[@fixtillbroke]

@@izzy76slo Does your fan shut off when you go into stand by, with the power switch on the remote or the faceplate pushbutton?

[@izzy76slo]

@@fixtillbroke yes it does

[@thersten]

Hey thanks for posting this. I had to shave my connector a bit for it to fit, but it works. One of the transistors burned before and I had to repair it. Hopefully that won't happen again.

[@hudsonrobert49]

You're welcome.

[@almariojr.clemente1746]

It has a thermal resistor switch! When reached a certain temperature it will auto turn on the fan

[@rpcomhem]

You just saved my day. Thanks 👍👍

I'm very glad I could help you

TURN OFF THE POWER before opening a receiver! And DO NOT touch any of the components - capacitors have a lethal discharge even when the unit of powered off! Also try not to carry or move the receiver when the lid if off. The chassis is poorly designed causing the boards to move and cause problems - or at least cause the HDMI's to fail. I added a fan from a TX-SR608 (that had the HDMI failure) to the inside of a TX-NR515 using the 'writing' 12v port and its working great. The connector fits straight in. There is also a dedicated fan 12v - but I dont trust it firing up the fan early enough.. The NR515 has the indentations on front fascia to accommodate the fan cage - - but the back chassis has no screw holes to fasten the back of the fan cage. I was against drilling new holes as of the metal filings that could cause a potential disaster. I used a good blob of hot glue instead which holds fantastically well. The unit is running cool and the fan is super quiet. Im amazed the TX-NR515 has no fan on shipping- after all, the ports are available and the front fascia has been built with a fan in mind. Penny pinching I imagine.

I have one tx nr 646 its works?its same?

[@dtwistrewind7361]

Sorry fella I haven't seen part one, had the original fan headed died or is it thermostatically controlled?

[@hudsonrobert49]

Hi for part one click the link here kzbin.info/www/bejne/foS4dpmfjdp6arM, the fan was thermostatically controlled,

[@vladdaniel7994]

I installed an additional fan to cool the dts chip and connected it to the 12v socket, but it doesn't stop when I turn off the receiver! What settings should I make to stop once with the receiver?

[@hudsonrobert49]

I have found that switching the HDMI through OFF then it doesn't stay on when switched off hope this works for you-HDMI through should be found in audio settings

[@scarydudu5826]

Can we plug on the board 2 coolers? Have you tried? Heating is the devil for this device.

[@hudsonrobert49]

Sorry I haven't tried as one keeps mine cool.

[@Tiger-dl1yn]

Good evening, but is the fan not to heat up the HDMI card?

[@hudsonrobert49]

it's supposed to keep everything cool inside but it doesn't come on until it gets extremely hot which by then it's Burnt things out

[@Tiger-dl1yn]

@@hudsonrobert49 thanks,i have the TX NR 905 which doesn't have a fan and i'm watching a lot of modifications on youtube, i.e. videos where they add a fan, and i don't know whether to add it too. what do you recommend?

[@hudsonrobert49]

@@Tiger-dl1yn sorry for late reply I would do it put a fan on it somehow if I could gets too hot

[@Tiger-dl1yn]

@@hudsonrobert49 thanks for the reply, the only place to mount it is outside above the grid of the HDMI board, which is where it heats up a bit, because the amp will be placed in the cabinet so you won't see it afterwards

[@dorszes]

The question is, why my fan in TX-NR828 wont kick in, when plugged to the right power socket? Will try to heat the thermostat with hairdryer to check if fan will kick in.

[@RuiSilvaPT]

It will turn on after the right thermal value is reached, it's common to act this way because no one wants to hear the fan when idling or not pushing the AMP on these equipments.

[@dorszes]

@@RuiSilvaPT any clue what's the thermal requirement to turn the fan on? Just wondering.

[@POWERMAXUM]

Will it work for onkyo 609??

[@hudsonrobert49]

Sorry I don't know

[@POWERMAXUM]

@@hudsonrobert49 thanks for your answer.

[@hudsonrobert49]

All I can think is if you remove the cover and see if there is a spare 12v socket

[@mrcrazyjonpresents4312]

Bloody typical by the time they made the 609 they decided get rid of that spare plug thing you plugged into

[@hudsonrobert49]

Idiots

[@POWERMAXUM]

Really¿ i hace 609 and i thought both 609 and 616 were Almost the same. Wanted to do the same

[@mrcrazyjonpresents4312]

@@POWERMAXUM You can do the same sort of thing with the 609 you just have to wire it up to a usb plug then plug it in the usb port
