Too Much Heat! Need Some Input - Blu-ray Forum

DrinkMore · 07-29-2007, 03:38 PM

I finally finished "touching up" out wire problem for our plasma and in doing so I decided to dust and clean up the receiver/cable box and ps3.

There is a big issue with the Onkyo and the Comcast box getting super hot. Hot to the point the metal can burn you. So, for now - the comcast box is sitting on its side (vertical) to allow the Onkyo to breathe much better.

I guess my question is, is there something they make that can raise the boxes a few inches above each other so more air can flow? I guess they would be called feet. These sit in a cubby hole so that might not help.

Anyone know of a super THIN fan that I could buy? Like a box fan but much smaller?

Thanks! I will post a pic.

I have the same issue. I would think you could just take two small pieces of wood and run them along the receiver and sit the cable box on that. That should give it some more space for airflow.

to the ppl with ps3's, if they have them close to the receiver i suggest notebook coolers. they're USB powered and do the same function as your willing to pay for that almost 200 dollar mechanizim. your looking at like 20 bux a pop. 3 powered fans, works good. (btw, i dont suggest stacking ANYTHING above the onkyo ESPECIALLY if its already in a tight spot. over heating it that much will cause damage. i say if you cant find a spot for that time warner box, then think about one of those coolers)

I have the same issue. I purchased a Nyko power cord replacement ($3.99) and a Link Depot 110v computer case fan ($17.99). Spliced them together and plugged it into the ac outlet on the back of the Onkyo so when ever the reciever is turned on the cooling fan starts and draws the heat out of the top of the unit.

Great idea on the notebook cooler...never crossed my mind.

DrinkMore · 07-29-2007, 05:11 PM

I took the PS3 out because there was so much heat. I don't think I will put the PS3 back until I find a solution.

Although that is a good idea. I might just buy a super small fan and put it back there. See if that helps.

WriteSimply · 07-29-2007, 05:40 PM

You can buy a whole bunch of USB fans and cool your system. Some are for notebooks and some are coiled. Just make sure you get a USB hub and a power supply for that.

You can also wire up cooling fans for PCs so long as you know the voltage and the fans are quiet. Good suggestions, everyone!

Sorry, I don't have a link, but I know there are several web sites that sell 80mm or 120mm PC case fans that have an AC cable on them. I mounted one of these on the back of my entertainment center behind my Onkyo to help with the airflow. (I think I bought it @ Radio Shack.)

My Blu-ray player is above my receiver, but on its own shelf that has about 5" clearance over the Onkyo. I won't deny that they both get hot (the receiver more than the BD player), but they are MUCH cooler than they were.

Was browsing my sites as usual and came across this if anyone wants to pick one up and try it out..

you might want to separate your 360 from your entertainment system...

that should fix the problem..

Hot to the point of burning? I would be more conserned about fire hazards than keeping my components cool.

I have lot of ventilation. I never stack my consoles on a reciever or each other it's got a lot of airflow, i tie my cables so that they don't block that good air flow (in my TV/Component center). Never have any heat issues. PS3 seems louder now, but It's been 90 degrees (average) with high humidity every day for a whole month. My room can feel like a sauna when i come home from work.

i got airconditioner, but i try to keep electricity usage down, so I use a ceiling fan unless it's totaly sticky. (It could be 87 degrees but humitiy make it feel like 95)

But i beileive more and more people are becoming heat paranoid. a good example is Hard drive coolers. I have two old Hard Drives from PCs made in 2001 and they were encased in rubber skin (like the ruber skins used on Ipods, and Wii remotes) i dubbed the HDD condom. These drive never overheated, they were 7200 rpm drives, but with only 2MB cache (made in 2001 what do you expect), and to my knowlege, still work today, just forgot where i put them. I beileive back in 2001, people were more worried about impact damage to their HDD causing loss of data than overheating, thus the rubber "condom".

Keep in mind that fans generate tons of electromagnetic interference (EMI). Keep them away from analog audio lines and your receiver if you can help it. Don't run the fan's power cord parallel to those signal lines either.

I keep my receiver on the top of the stack so the heat can go straight up. Also I've found that the PS3 stays at a lower fan speed if it is standing up.

How exactly do fans generate EMI? They are a bearing and plastic. If the AC cable from the fan is shielded (as, ya know, most are) it shouldn't generate any more EMI than anything else you've got. In fact, it would be far far less because it's such ridiculously low power use.

Guys, Onkyo designed these things and I am sure these units went thru a rigurous QA effort. If Onkyo didn't put any additional exhaust fans on it, it's most likely not needed.

Just make sure you have plenty circulation around and above the unit. I have about 3 inches between my unit and the shelf above. Yes, my unit gets very hot to the touch as well, but I am confident that if you follow the ventilation instructions in the manual ... you have nothing to worry about.

Agreed. The electronic components inside probably have a max temp of over 200 degrees Fahrenheit. Keep in mind that there are heat dissipation components inside the unit casing, but the case itself is made of metal and thus absorbs much of the heat that gets "blown out" by the fans and such. I would only WORRY if I started having performance issues. If the heat is too great, the receiver will hiccup long before it's in the danger zone of failure.

That said, the reason I personally use an auxiliary fan on my entertainment center is because I having closing doors that hide the components, thus trapping the hot air inside the center. The fan is to help remove the ambient heat floating around in there.

An electrically charged magnetic motor perhaps? Otherwise it wouldn't be a fan, it would be a windmill.

Also, PS3's need to breathe, move it out on its own, it helps, really. Get a stand and put it on the floor near the TV/components, not with them.

Do you have a notebook cooler under your PS3? If so how loud is it? Also, was your PS3 fan loud before?
