ok im on a mission today and i can't find the answer.
what is the conversion for watts to celcius when your talking cpu's.
ive seen the equation before and for the life of me i can't find it and its going to burn a hole in my brain until i find it.

now i know one of you math geniuses knows this ive seen people post it before i just cant find it here

??? Watts is a measure of power and degrees is a measure of temperature. You can't just say 100w = 1°C rise in temperature because 100w is going to raise the temperature of something thats small a lot whereas it won't do anything to the temperature of a chunk of iron.

You cannot do that without knowing the thermal transport capacity of your cooling solution in your environment. And that capacity is certainly not constant, so you have a pretty big mess on your hands if you want to develop an approximate formula.Originally Posted by Lestat
There's a formula for watts to Joules, of course, but none for watts to Celsius like uOpt said. In theory it kinda makes sense as heat and energy are related, but they're not directly comparable.
yes there is and when i find it .....
now it could have been a calculation per cpu brand, i cant recall.
but you know as well as i do a 65w cpu runs cooler than those beasty old 150 cpu's is that cuz of the voltage ? no cuz they actually run similar voltages, its the wattage output of the cpu.
have you never heard of 150w of heat ? now i know as you that there are 1000000 other variables to take into consideration that can change that temp, its just a temp at the core of the cpu.
i know when i did find it it took lot of searching but the guy had a calculation to tell you volts, watts, cpu freq. = such-n-such projected temp.
it also wanted to know the thermal conductivity rating of your heatsink.
its not a simple watts to celcius calculation i know that, but there is a way to figure the thermal/wattage rating of the cpu to degrees.
hopefully me just describing it more helps.
oh its frustrating cuz i had it bookmarked before i reloaded my system last time and i never said my bookmarks.

Yea power (watts) is dissipated across a resistor in the form of heat.....but this isn't a direct comparison, as this relates to serveral variables as stated above. Such as resistance, current, voltage, capacitance.......

remember the 2nd law of thermodynamics.
The only W/°C rating I know of is for heatsinks, which basically is the measure of how much heat can be dissipated.Originally Posted by Lestat

yea and that is because its one solid element or compound, not a mix. that relationship isnt linear either, imo the best way to test is to actually do the trials. increase the voltage and see how it affects the temp. its most likely logarithmic, and after u plot a bunch of points u should be able to use any graphing program to derive a regression line.Originally Posted by Kobalt
But then you actually have no way of measuring the wattage of CPU at different voltages. It can be done on a dummy heater - i've seen such thing on some polish site, they have built a copper block in shape of CPU core and it's heated from inside by heating spiral (don't know the right english word). There you always know the current and voltage and can measure watts/celsius curve for a cooling solution.
