You're both right I should say. I myself have hit more than your so called "temp limit of 62 degrees". To be honest, throttle never happens before the chip hit 80 for more than a few seconds with mine. I even run mine with temps hitting 90s. But like Mega Man said, it's okay if it's just for benching.
Thermal shut down happened on me once. That's when I hit 89 right after doing a Cinebench CPU test. System shut down halfway the test. If you've been doing Cinebench, you'll know for a fact that even if you have Primed your chip, You'll hit higher temps when doing some rendering. That man, should be your concern. Gaming can't push your temps to the wall. Even if you've hit past 65 just to get your chip stable at let's say 5 GHz, you don't have to worry as long as you have already set your goal on the things you will be doing with your chip.
If your rig is involved with serious rendering, It's advisable to stay below that 65 degress wall when stabilizing your chip. As we know for the fact that rendering will push your chips past any Stress softwares out there.
If gaming is just your thing, you will never hit the temps you'll get with prime or whatever.
One thing to note too, people have been preaching about that temp limit for the chip. And one man already said this, "you've been preaching about that number (62 degrees I believe) to everyone, yet you also have the nerve to run your chip with Prime for 24 hours? or even just 7 hours? and say you never hit 62?, but how many degrees far from 62 were you for all those times? 5 degrees less? Let's be realistic people.
62 for sustained operation, the way my head understands this is that, at extreme cases, you should not run your chip past that temps for operations that require hours to complete. Temp spikes will always happen for a short time. But if it's sustained for hours, truly your chip will die. (assuming no thermal shutdown or protection causing your chip to throttle down happens)
"Also, voltage never create heat. Amperes or current do"??
Man you should also point that current is directly proportional to voltage and power. Power, my friend, is what gives you heat. You should not point out one and neglect the other.
P=VI ; it only happened that your voltage do not wander far from the setting you made. +- 0.1 volt at the maximum while your current depends on your load. But it's wrong to point out that current is the one creating your hight temp.
You also made a very EXAGGERATED example on how current and voltage relate to heat. 0.00001 Amp and 200 kilovolts would give you a power of what? 2 WATTS? that 2 watts my friend will not really give you enough heat.
what about the other way at same power. 2watts with 1 ampere as you said, will need just 2 volts. Can you say that at exactly the same power, increasing your current 10000 times will put out more heat when voltage dropped from 200K volts to 2 volts? NO!
In your example, assuming the voltage was keep the same at 200Kvolts, and current jumped to 1 ampere, MY FRIEND, your current jumped 10000 times. Don't you expect a 10000 times jump in power too? And 10000 times more heat?
Again, the other way around, 0.00001 ampers with 10000 times more voltage, are you saying the heat at increased current will be higher than when voltage itself went up at the same factor?
So give a more meaningful example my friend. At 1.55 volts and (assuming the chip handles or can pulls out 200 watts like it's rated TDP) again, assuming TDP=Power Draw (they are way too different that explaining this exactly will be longer than your screen can display), current draw will be =129.03 AMPS!!!
What if you experience Vdroop, and your voltage dropped from 1.55 to 1.50 volts, your current will rise to 133.33 AMPS!!! That's a 4.3 amperes increase. how much more heat will that give you? too small my friend.
That again is a problem. You see, in any electronic system, current draw is always limited by other components. And once your voltage drops, don't expect your chip to pull out the same amount of power or more current. Since voltage will NOT ever drop when there is plenty of current.
In your MOBO and CPU for example, If enough current can be drawn at low voltages, your chip will still run since it is assured that voltage will not drop off its value even when your chip will run on full horses. But because that thing never happens, you need to increase your voltages. Since other components limit the current draw. That will put out heat since voltages like I said, like current, is directly proportional to POWER.
Bottom line, POWER, VOLTAGE, CURRENT are all in a circle. But in an electronic system, current is the one limiting factor. That is why voltage has been given an option to be increased when power is needed.Edited by mus1mus - 9/27/13 at 5:18am
