O2 Heating Problem

[bendejo]

Ola Amigos

Have had the O2 since Nov. 17 and REALLY love it. It got a good work out during a 2 week trip to thailand and everything is wonderful-video playback, pictures, sound quality and overall operation. I will write more about all this later; however I am concerned about the lower back portion of the player become very warm during operation, but not during charging with A/C adapter. None of my other cowons-2 X5L's, G-3. Anyone else have this experience? I will probably return to amazon US if this is abnormal and get another one.

How long does it talk to get "very warm" once you turn it on?

[bendejo]

After watching a video for about 30 minutes, the player begins to feel very warm, not hot. With music, it takes about 60 minutes. Since I have not this issue discussed anywhere else in the forum, I believe it may be just my player that is defective. As I previously said, this is one of the best players I have ever seen or used and LOVE IT.

I did find mine tended to get warm but it did die and had to be RMA'd. when it died it stayed warm......maybe yours has a similar problem to mine....mine died all of a sudden. Details here: http://iaudiophile.net/forums/showthread.php?t=24174 btw could someone please show me how to embed a link in some text?

btw could someone please show me how to embed a link in some text?all you do is type a word such as "Link" and highlight it then input the link with the insert link button.

I haven't noticed a heat problem but I haven't used it outside of the leather flip case much which might make it harder to feel the heat. I'll check it out the next time I have it going for a while.

edit: I checked it out and after a 25 minute video the back was definitely a bit warm but not hot in my mind. After another 25 or so minute video it was maybe a touch warmer but if it was it wasn't by much.

I only play videos on my O2 (which is now on its way back to Cowon - touch screen stopped responding to touch) and he bottom portion of the player always gets warm. Maybe it's a videochip and the heat is normal?

[emorphien]

Don't know what's down there but I am not really thinking anything of it. With the processing that goes on inside it I would expect there to be some heat.

i usually can't distinguish whatever heat goes on between my body heat and the o2 when it gets warm.. i wouldn't worry about it until i saw a significant drop in battery life or charging issues. The warmest mine got was when i used it with it plugged into the wall. I had it on the calculator while i was doing homework and it got pretty darn warm, but i didn't worry that much.

Ok but is it normal for the O2 to warm alot while only charging? (that's my O2 [sad])

Yup, definately[yes] Not so warm as to be uncomfortable but indeed very warm indeed.....I'd say 5 or so extra degrees.....

[schris]

Same problem with mine~ sometimes (not always) gets very warm~
I guess more than 5 degrees ...

I charge my O2 nightly... if I take it off the charger while the light is red (meaning still charging) the player is pretty warm.

I haven't paid attention to how warm the player is when I take it off the charger in the morning when the red light is off. I'll check it out tomorrow morning and edit this post.

Other than that, my O2 is cold when it's not charging and is not powered up.

let's hope it is a portent of the amazingly beefy processor in it that will allow it to tear through any apps made for it..........

[BruceBanner]

i think the heat is largely due to the small little cowon elfs whom make small camp fires within the o2 to fool us into thinking the o2 is actually a useful electronic device.

Actually, if it's a DaVinci processor as I've been lead to believe, it is rather beefy. During development for the O2 I made a program to repeatedly fill the screen with random pixels. With no text library yet I cant get a definitive framerate, but it goes fast enough to where you see flickers as the screen refreshes but you couldnt come close to estimating how fast. If you consider that is 130560 random values likely over 20 times per second, and that generating a random value isnt the easiest task to accomplish, its realy quite a feat.

Another rather subjective but interesting benchmark is my bounce and pong applications before I implimented timing code, so the speeds the balls moved at were entirely based on the processor speed. The O2 versions ran about 2-3 times slower than the version compiled for my 2.6ghz linux box. Thats not to say its really that fast as they are both quite different processors, and the rendering and such was done in a very different way between the two. Regardless, I suspect the O2 will be fast enough for most anything we would want to do with it(realisticly).

With the beefy hardware, the O2 is likely to get a little warm. The davinci processors seem to have a 200-300mhz ARM processor, plus coprocessors for decoding video. Also, obviously, battery charging in any form generates a good deal of heat.

Go back to your Touch or w/e.

The O2 got warm after about 1-2 hours of Video usage for me. Playing audio does nothing to the heat.

Thank you Queue for the comment to Mr. Banner. This thread is about the heat on the O2. After using mine about 5-7 hours per day since mid november, I think it is just normal. My laptop gets much warmer than the O2 and when I originally posted the comment, I was a little nervous because I have always waited about a year after the release date until purchasing a new electronic product. But with the 32 gb of the O2, combined with the expansion slot and ever superior sound quality of all my previous and present cowons, I took the chance. I really don't think the heat is anything to be overly concerned with. Enjoy your O2's.

it's Dr Banner actually.

Don't make him angry, O2 "overheating" will be the least of your concerns.
