Anyone have a good estimate of what the max safe temperature for the armv6 cpu is? I have setCPU configured to throttle back at 46 degrees, but could that limit be safely set higher?

Curious about this too, I have mine at the default of 50 °C
Sent from my Liberty using XDA Premium App
What I was able to find out in the past was that a mobile phone cpu could safely reach up to 80-90°C. The motherboard and/or components on the motherboard can start to fail around 65-70°C. And for a lithium-ion battery it's best to keep the temp under 50°C for longevity, 60°C is absolutely going to affect battery life. I was never able to find anything specifically on the armv6 or where exactly the temp sensor is on the Aria. I have setCPU configured to throttle back at 46°C, and I have the charging profile throttled back because of the heat generated when charging.
Just remember that the temps being monitored are the battery temps. The aria doesn't have the ability to measure actual cpu temps.

Right, so the CPU could probably take higher, but it's the battery that's the limiting factor.
I think I'll keep the profile as it is now, by the time the battery hits 46 that's hot enough. Don't need my Aria bursting into flames from thermal runaway.

For now just use the overclock widget. set top two settings as high as you want up to 998 click on off screen frequency. set between 246 and next number you choose. set at boot save. define settings at what mhz you like and experiment. do not run on screen and off screen freq at max. i have had my battery sweating and even plugged in all day and not gained a single % of charge. until boot loader is cracked.... this is all you can do.

Although it's impossible today because of bootloader, note it's always dangerous and not great to overclock embedded cpus.
You can't overclock a lot, as you have a battery (X10 works about 5-10 hours with full speed - 998MHz), and the CPU only has passive elements to cool. Overclock can damage your CPU and your motherboard, stress all elements and low your battery life (battery charge and cycle of charge). (Even there's a self shutdown when too hot)
You can get an idea of overclock on Nexus forum, as we have the same CPU (Snapdragon 8250) - I saw overclock up to 1300 MHz, but it's really not looking safe to me
Thanx everyone..

Depends also on the voltage (as long as your voltage isn't increasing as you overclock, it isn't really that harmful as long as you watch the heat), and what you have your underclock speed set to with screen off (as this can in some sense reverse some of the possible "damage")...
I had my htc hero overclocked to 710 with the screen on, and underclocked 176 with the screen off and it ran a lot better.
I digress, I see no purpose in doing so when you already have a 1ghz processor that is super fast. I only really see a point in overclocking if the possible benefit is greater than the possible harm, and in this circumstance, I really don't think you would see that much benefit.

I have seen considearable difference when maxed out. however the dangers are high of overheat. ive done it once and onetime only. kept on and off screen at 998 and hat it plugged in all day with out a single gain of battery. it was like on life support and was hot enough the phone was sweating even when sitting next to a fan blowing on it constantly.:-( since then i have made adjustments to run between 700 and 998mhz on screen and min 246 and 400mhz when screen off.
if looking for better performance without the overclock and good drain of battery, download and install sysctl from market and follow settings below.

Not in all instances. Depends on the quality of the chip. Lot of chips are capable of handling higher speeds and temps but are set lower quality assurance.
For instance, I've got a NookColor that has base CPU set at 800MHz and is now overclockable to 1.2GHz
We'll have to do stress tests on some to see what they're capable of.

Well don't say that if you are not sure. 61°C is high, but no way you can say that as insane.
I was reading some articles about Cortex A9 CPU's and found this,
http://www.phytec.com/products/som/Cortex-A9/phyCORE-OMAP4430.html
So the TJ Max of the CPU is 85°C. But for safety you shouldn't let it go above 70-72°C.
But do remember one thing, that is the CPU temp I was talking about, not Battery temp as you mentioned. It's very common that Battery temp will get higher if CPU temp increases.

Yeah, people see battery temperature, but 61 degrees seems pretty high. My battery didn't pass 48 degrees, even when playing complex games. A high temperature will shorten battery lifetime and there has been one report on this forum about plastic inside SII melting down cause of heat, but no info about the temperature that melted it.

Well the battery & CPU, both temperatures are also depending on the ambient temp. It is also advised to mention the ambient temp along with battery temp.

Normally mine operates at 42-46. Maybe it's because I live in a tropical country. Once it got to 53 degrees celsius. Got kinda worried, don't know whether to take it back or not. Is this normal?

Hey all,
I've been noticing over the past few times I've been playing GTAIII and MC3 that the internal temp of my phone rises drastically, to a point where I can barely hold one side of my phone without having to let go every few seconds because it is so hot. From where the battery is positioned, I assumed it might be the GPU heating up, but other att gsII users said their batteries were heating up.
So,
1) Is anyone else experiencing these problems
2) If you are, has anything happened to your phone
I'm debating whether to trade it in for a new one, because I'm still under warranty.
Welcome to high performance electronics. If you push the CPU/GPU hard it's gonna heat up. It's like a desktop, if you do something CPU/GPU intensive it'll heat up. It's a simple byproduct of inefficiency.
As to batteries heating up, that could just be because they're close to the CPU/GPU. Batteries will warm up under high current draw as well.
Do you have a case on your phone? Those tend to trap heat in as well.
Sent from my SGH-I777 using Tapatalk
If your phone is overclocked, the processor will be running at the max clock you have set while playing the game, which is higher than what it's supposed to be running at, i.e., the stock clock. Prolonged usage at this higher-than-normal clock will generate excessive heat.
Sent from my SGS II.
Yeah I don't play GTA3 anymore because of this kind of stuff. It doesn't get to the point where I have to literally move my hands because of the heat though. I simply don't like my phone getting even remotely warm. I'm just really anal about stuff like that. I fear that doing it will shorten the life of the device and I love this phone way too much to let that happen.
I'm sure it's designed to run at these higher temps since mine is completely stock with regards to cpu speed and voltage. If I can't play a game due to this, then I simply pass on the game. Same with my computer but I digress...
Download an app to check the temperature. Yes, ideally cooler the better, but the phone is designed to handle a certain amount of heat.
From what the op is describing, that is definitely too hot. Over time the components life can be shortened. But what you'll see first is your battery life going down, even quit working all together.
Underclock the processor. That can help keep the heat down. Even as low as 500mhz can pay many games. 800mhz should be plenty for most high end games.

I'm not overclocked, but yeah, same thing happens with me when I play MC3. I got scaredish since it got a bit too hot, seemed more hot than it was supposed to be.
download the diagnosis app and set it to check your batt temperature, if that gets above 45c I would be worried and think about underclocking/undervolting.
As long as your phone is cool enough to handle, don't worry. There's a lot more to it, but the electronics can take a lot more than most people credit them for. The battery is the most sensitive to temp, but so long as it's not for terribly long periods of time, you shouldn't even notice any additional degradation over the long run.

Average day to day operating temps are between 30° and 40° celsius.

If anyone's interested, I have pretty much eradicated the heat problem while also boosting battery life and conserving performance. This was done through setCpu: http://forum.xda-developers.com/showthread.php?t=505419
The problem was that apps were just running the processor like crazy on the 1.2 GHz speed setting, and it used a considerable amount of juice that was unnecessary, heating up the battery to a ridiculous amount.
But anyway, here's the profiles/voltage settings I use:
Main Governor: 200 MHz - 1200 MHz on demand
Profiles:
- Charging, 800 max, 200 min, ondemand, priority = 100
- Temp > 44.1 Celsius, 500 max, 200 min, conservative, priority = 100
(this is a conservative temperature, but most place the *dangerous* amount of heat at 50 degrees before battery life starts decreasing, the CPU/GPU components have solder that melts at 70 degrees)
-Screen Off, 500 max, 200 min, conservative, priority = 75
-Battery <25%, 800 max, 200 min, powersave, priority = 75
-In Call, 800 max, 200 min, conservative, priority = 50
Voltages:
(I was able to undervolt by 50-75 mV for each and still remain stable, these are tested btw)
1600 MHz - 1400 mV
1400 MHz - 1225 mV
1200 MHz - 1200 mV
1000 MHz - 1100 mV
800 MHz - 1025 mV
500 MHz - 950 mV
200 MHz - 875 mV
and that's it! It's working great, I don't have the heat issues I used to, now I can play graphically demanding games and the temp doesn't rise past ~42 degrees, pretty solid improvement. I also get 24-28 hours of battery life with 2-2.5 hours of screen on time per day.
No need to worry about this. That's nowaday phones designed to be. Just normal heat.

I agree that's how they're 'supposed' to be. But things mess up. AMD processors are designed to handle heat, but they are still known for getting too hot and damaging the graphics chip. Better safe than sorry.

Agreed. theory and actuality are two incredibly different concepts
I have my SGP5 overclocked to 1.5ghz at the moment via Tegrak. Everything is running smoothly but the spot on the back where the CPU is gets warm to the touch. Not hot or anything, but obviously warm.
Before I had it overclocked to 1.45ghz and it stayed a lot cooler, but to get to 1.5 I had to bump the core voltage to 1.35v. I also have the up-threshold set to 35% so it spends a good amount of time at max speed.
Since these things don't have CPU temp monitoring, how do you tell when it's too hot? My battery temp never goes much over 80*F, so that doesn't seem like a good indicator of anything.
Sitting here playing music with Mufin my IR temp gun reads a max of 100*F on the back of the case over the CPU. Battery temp is reading 77*. Is that too warm? How much of a temp differential can there be between the outside of the case and the CPU itself?
I'm no noob to overclocking PCs, but this is my first Android device so I don't really know it's limits as clearly.
Any help would be mucho appreciated!
DISCLAIMER - anything within this thread has the potential to do permanent damage.. I haven't had any issues yet but will not be held responsible for any damage!
So I just pulled the back cover off it. Running the same program for 10-15mins the CPU never exceeded 82.5*F which is well within safe limits imo.
I guess that goes to show how poor the cooling is in one of these things with the back cover on. I'm going to keep running 1.5ghz and report any issues. The difference in smoothness between 1.4 and 1.5ghz is pretty dramatic.. web browsing is very very smooth now. I probably won't be going any higher than 1.5, but for now it seems safe.

Ondemand from my understanding, scales processor speed using the values in the up/down (I believe System Tuner refers to down as "powersave bias") threshold. From my experience it's the best governor to use as far as customizing it easily and getting it to respond well.
Whatever you set the up-threshold to, when CPU load exceeds that value it bumps the speed up to the next "level" and ending in full speed. Then when CPU load falls below the down-threshold, it scales it back down to the next lowest level, so on and so-forth. You can also adjust the sampling rate too - lower frequency means it checks the CPU load more frequently and essentially makes the governor more responsive.
When I set mine to 35%, almost any program aside from stuff sitting almost completely idle will trip the CPU to hit 1.5ghz. This makes everything real responsive and may use more battery.. but I prefer having a more responsive device. You can also adjust the up-threshold to a higher number to try to lower temps and extend battery life. You can really play around with it to suit your needs, there's not really anything to screw up there.
There shouldn't be any danger using it with the ondemand.. but since I haven't tested this for more than a few days right now just keep an eye on temps (especially while playing games) and watch out for any "stuttering" out of the blue. Mine gets warm but nothing excessive. You'll be able to feel it on the back between the speakers.
I have to say though, even running such a high clock speed I'm not really seeing any negative effect on battery life so far.
Lemme know how yours goes!
How can it not have any risks? When the heat is too much somethig will explode wouldn't it?
No just kidding, but seriously. There is a risk of overheating a hardware and 'destroying' it, there should be!
Sent from my GT-I9000 using XDA
Well of course there's always some risk in overclocking! Especially when you don't know what you're doing.
As far as using one governor or another though.. when it comes down to it there shouldn't be a huge difference.

Hi, I've got an annoying problem...
As far as i know the first thermal threshold for kicking down the CPU freq to 800MHz is set to somewhere around 80oC in SGS3. But in my case it kicks in after achieving just 51-54oC which makes some games unplayable after 5 mins
I've read somewhere that the battery temperature (45oC or so) is also considered when throttling down the CPU frequency, but my battery hits just 41oC when it happens...
Could it be a faulty temperature sensor(s) or just faulty almost 2 years old battery? I have no more clues, could anybody help?
Thanks a lot!

That's tricky... Afaik you CAN change some system files to avoid throttling but I don't believe that that would be healthy... Your temperature sensors could also be faulty... I don't know

yeah, but is it possible that it's throttling down on such normal temperatures? Or maybe there's another safety mechanism involved (dunno, maybe GPU temp sensor)? But my GPU runs on stock freqs and voltage...also it doesn,t matter if i'm undervolted on CPU or not, still the same
