Best cooling fan for Onkyo 876.

anhchungdoan

As much as I love my new Onkyo 876 but I have to deal with heat. Yes, heat in a small 14X16 room in a winter time. The Pio SC05 in another room is cool as cucumber all the time.

Even in stand by mode, the 876 is warm. With my Sanus Modular stand, I have only 1.5 " clearance on top so it starts getting hot after 1/2 hour of playing. I use the 110 Volt 10" fan to circulate the air then it's cool to touch but the 10" fan at low speed is running loud and can be heard 4/5 feet away.

I need assistance from 876 owner to find a quiet 110v fan. Thanks in advance.

I am awaiting for my BXT-dual fan (50mm) from BuyExtra.com however Id like the idea of 110v quiet fan if it can be found.

Thermal Solutions? (I think thats the name) makes excellent, very quiet cooling devices. They are a bit pricey, but I owned one and it worked very well. They are very quiet, and use the fans at 1/2 speed to accomplish this. They use a thermal switch, which i bypassed, and simply turned it on anytime the amp was on.

If your Onkyo has side and/or bottom vents, it's probably best to "pull" (vent) the warm air out, rather than blowing air in. You can switch the fans around to accomplish this. Also, blowing air in also blows dust in---something to think about. I used mine in this fashion to exhaust hot air, and encourage flow across the heatsinks on my Parasound HCA-1500 when it resided in a closed rack some years ago.

I have ordered an extra Sanus audio rack and 5 extra 12" poles to raise my clearance up an extra 3" but the people at Home Furniture savings took my money on Dec 2nd and they had not even have a tracking number for me. My order is in "stage 2 processing". What's a joke ! I should have ordered the Sanus from Rackandstands but they run out of the 12" poles.

Do you have the model number by any chance? Thanks.

Here you go, it's "Active Thermal management." Here's the "CoolIT", the model I had. They have numerous others

I'd recommend putting some stick-on rubber feet from radio shack on the corners, rather than having unit sit directly on your equipment.

Thank you, guys. Good info. Now I have to search and make a decision between the Cool thermal and the Parasound Breeze since they are in the same price range.

Why don't you build your own fan/enclosure? Like some of the Middle Atlantic cooling fan units?

'cause I am an idiot when dealing with soldering and electrical connections. The biggest project I've ever done is to install my ceiling fans:D

I look at the web-site mentioned and I wish that I could do it myself but ...:(

I would be looking at PC fan's, you could get much more for your $$$

Believe me, I did but most of them do not come with the power supply. I wish I know or some one can show me how to wire the 3/4 pins to the powe supply and what model or part should I look for.

I went to Ratshack and found some PC nice fans but the clerks have no idea what else do I need. Bummer!:D

The tough part about DIY is getting the fans QUIET. I tried a few DIY's useing Vantech stealth fans--still waaay too noisy.

It's not a big deal if your equipment is enclosed, but if its open, it'll annoy the **** out of you.

The Active Thermal CoolIt-II is so quiet, you have to put your ear up to it, to hear it.

You need a power supply. A 12V DC power adapter will work, so will the ones from an answering machine or cordless phone.

Just make sure the output of the power supply is enough for the draw of the fans, i.e. if you have a 500mA power supply then a 300mA fan would work.

I am not sure about the other products people are recommending as i have never seen/heard of them. Another option to consider is a laptop cooling pad. You can place it upside down on top of the onkyo. When i was looking for cooling solutions this was recommended to me and is a fairly cheap alternative. I have since purchased a new stand and do not have the AVR in a enclosed space so heat is not an issue.

A laptop cooling pad would work too. If you have a device with USB (HTPC, cable box), you can connect it to that.

Bought one of the unit. Super quiet and effective. I cound not use the steel case, so I added 4 rubber feet to each fan and place them on top of the Onkyo 876. Highly recommended for Onkyo owner with tight space above the AVR.
