Overclocking will show a slow linear temperature increase the higher the Mhz, overvolting will show an exponential increase of temperature.
    I agree with you on the fact that electronics are not as sinsitive as people think, the problem with this statement is the biggest concern is not whether or not you cook your chip, it is what happenes to the battery when it overheats.

    I also disagree whither this whole voltage not increasing BS. Anyone who understands even the most basic electronics (primarily ohms law...V=IR), will realize that voltage isn't what causes things to cook, its current. Every time the CPU does an operation the chip pulls a little bit of charge through it, and when you overclock, you increase the # times per second that this occurs. The result? More charge pumping through the Chip in the same amount of time. This current spike increases the CPU and battery operating temprature. This may not cause catostraphic failure, but will significantly reduce the life of your hardware, especially the battery.

    That is not how CPUs work. CPUs can work just fine up to a certain MHz given certain conditions. The main condition that increases temp is voltage.

    Quoted for truth

    yes overclocking regardless of voltage increase or not will increase heat from the higher loads it can run and it "might" decrease the life of your device depending on what how aggressively you overclock and how you use apps like setcpu to underclock when you don't need the full speed. This results in better performance but cooler temps and better battery at the same time depending on setup.

    But it's heat that kills the chip. At least from personal experience.

    also of note is the fact that noone really knows what the cpu temp is unless someone has opened up their droid and put a sensor probe on the actual chip. All the temp sensors are reading the battery afaik. For most people concerned with overclocking battery temp seems to be the biggest issue anyways.

    Uh...not even sure what you are trying to say. Maybe I should take over. You generally can overclock systems in two ways: 1. Modify the oscillator which is what sets your clock speed (generally a hardware modification) or 2. upscale/downscale (Software configuration). The way upscaling works is it "tells" the systme to perform x numer of operations per cycle or x number of cycles per operation. The operations usually take fractions of a cycle, so there is genrally lots of "dead" time where your CPU is doing nothing. This is why people find it terribly usefull to overclock their systems because theoretically they can handle it. All types of processors in current technology are essientially a wafer of silicon with millions of transistors printed on them. Any time one of these transistors cycles, there is a voltage drop across them. Where did that energy go you ask? It is converted into heat. You increase the number of times that happes every second, you get increased heat.

    If v=I xR then v/R the more voltage u have the more current so voltage does inturn cook chips. I know what ur saying just thought I would add some sarcasm!

    But in a chip voltage is what variers and current is rather fixed so overvoltages causes the heat issues along with fast switching as the person before me stated

    I am not going to quote anyone on this for several reasons. There are pieces and parts of each of the above posts that are right in their own way.

    You can't change OHM's Law. Heat is created by resistance, and the amount of voltage applied to that resistance. When over-clocking, you are not varying resistance, voltage, or current. You are varying CYCLE's. Therefore you end up with more heat because the CYCLE time does not allow for the device to cool as it did prior to the over-clocking.

    It is nothing more than that. If you had modified the voltage applied, resistance (load), you then would in result modify the current being drawn.

    well there is an app that actually reads the CPU temp sensor called Temp monitor but it only works on the newer Tazkernal overclock. And i notice there is no major temperature difference.

    I used to have my phone OC to 900mhz, I saw no diiference in performance and actually caused some performance issues. Plus my phone ran real hot and the battery life decreased, ended up going back to stock where it was more stable.
