What temperature is considered "overheating"?

I have been overclocking my CPU lately, sitting good right now at 1.2 ghz. I have it undervolted as well to prevent overheating. My question is what temperature do you associate with too hot? 100 F? more?
I dont like letting my phone get over 95 F, but im just curious to know what is considered a safe temperature range.
I cant directly measure my CPU temp, as that feature is not offered on our phone which really sucks, i have to go by the battery.

I have not the slightest clue but I would think you would go by how it feels in your hand and whether or not you can "smell" the cpu burning. I usually dnt clock it above 1.2 unless I'm gaming which is bad but I have it setup by a laptop cooler so it never overheats. Id say anything more than 90 would be pushing it.....

Not true put it like this our phones automatically shut off @ 122*F I go to 115*F when i play GTA 3 @ 1.5Ghz, but i can clock to 104*F just streaming music on WiFi.
So id say personally probably around 110*F+
Yes 105*F is hot but don't run it that high forever though.
But thats the battery, CPU stays fine so id say if your running 100*F+ For more than an hour than it might overheat??? Not completely sure but like i said everyday i play GTA 3 and get up to those temps.

Do you undervolt your cpu or run it on stock cpu voltages? I'm currently running samurai assassination and my phone always crashes if I undervolt it, and usually crashes when I run it at max voltages, but only when I overclock.

I would consider 114 f overheating, that's when I have setcpu underlock to 800 mhz

Used to but because i play GTA 3 now i dont if undervolt that defeats the sole purpose to overclock so i can play without lag, once you undervolt it decreases performance but however gains in battery life.

His epic is weird undervolting drops his preformance whereas mine increases preformance......

I would agree, 105, 108 would be ok but not for extended periods. Taking the back off usually cools the phone almost 5 degrees for me, but Epics are weird

Sure there is... maybe not for you... I have 5 different profiles set... 1 for screen off.. 1 for battery < 50%, 1 for battery <30%, 1 for temp >116, and 1 for in call...

Yes and has ability to set I/0 Scheduler plus setcpu reads wrong. And is outdated.

I'd say that everyday during the summer in Phoenix I'd be overheating as the daily temp rises to 115+ for weeks.

I do this too, for the battery anyway. If it overheats I uc. If I'm under %80 I uc to 800, %50 600, 30% 400

But not an option to Overvolt, and choose an i/0 scheduler. plus its a bit faster to use and works with other programs nicely

Is there any overheating on your Arc/S?

Just wanna know that is your phone have any overheating problem when doing / playing games, and is that normal for getting 50°C of the cpu?
Sent from my LT18 using xda app-developers app

mine heated up pretty bad when I did play games, but I don't know what °C is considered an 'overheat'

Every damn time when I throw in ICS on my Arc S - the overheat problem is there. It's frustrating.. Specially when trying all available custom ROMs.

Anything over 40 degrees is considered harmful to your phone in general.
I've had my phone to warm up to almost 45 degrees. GPS + Data is the culprit for that. Games can also heat the phone up as said before.
Sent from my LT15a using xda app-developers app

Ive only noticed it gets a little hot during charging. I dont play any games

well, how exactly you monitor cpu temp? I only know my battery temp, 37°c right now. when use data temp can raise to 45°c, cellular signal here pretty bad here.

Is there an app for checking cpu temperature I can't recall finding that in settings?

What's the highest temp you have seen your phone at? Mine currently is at 105° f

I have hit almost 120 F before. Not much to worry about if you're a casual user. Thermal throttle should just kick in.

highest ive seen is a cpu temp of 109C. btw 109C = 228.2F. the devices safety shutdown is at 110C. i have a feeling that you posted a battery temp of 105F. 105F for a cpu temp is quite cool, considering the body temp averages at 98.6F.

Oh, I assumed you meant the battery temp indicator that most programs give out. I'm not sure what I've hit on my CPU, but if you hit a temperature too high, cpu or battery, thermal throttle will either scale down the frequency to cool down your processor or turn itself off/reboot if the cpu or battery hits too high of a temperature, thus saving your phone.

thats battery temp. the trinity kernel toolbox shows cpu temp.

Cpu Temp

Hey all, any idea how hot it is safe for the cpu to run? Using trickster mod to read the cpu temp after a few hours my cpu can reach close to 70 degrees Celsius and the screen feels hot. That seems a little insane. I thought it was aosp rooms causing this but after switching to i747z I can confirm that is not the cause of the heat. What do your cpus run at? Any ideas?

Mine usually stays under 100°F.

I wish mine stayed that cool! I'm consistently around 120 farenheit with the screen on

The battery temp or the cpu temp?

Mine tends to get hot too, sometimes almost too hot to touch.
But never over 70F.
Usually between 20F and 60F, it tends to stay around 50+ during activity.
Im not really comfortable with how hot this thing gets sometimes. I'd be downright alarmed if my cpu temp was over 100F.

Oops, that's battery temp
CPU temp seems to stay around 40C
My bad!

Okay guys this thread gave me the answer i was looking for

Turns out at 70 samsung starts throttling the kernel to cool it down so anything up to 70 celsius is totally normal

Is this cpu temp normal

I have lyapota kernel with undervolt but get this cpu temp. Is this normal?

That looks extremely hot my friend, I have never seen mine that hot.
What was your phone doing to reach those temperatures?
What are your settings?
Which version of kernel?
Governor?
Voltages?
here's my temps
Using lm#17 pre aroma
-75 cpu undervolt
Even under full load I'm only seeing a maximum of around 50-55

Highest at 81°C is normal...it won't go pass that. Stock kernel capped at 85°C. When reach at that temp, CPU will be throttled to maintain below capped temp.
Just don't play heavy games while charging. Almost can fried egg with this phone. [emoji39]
