Will the REAL CPU temperature please stand up? - Page 3

post #21 of 29
lol ya silicon melts in the 1000+ C range lol.

And for the record...my bro's Intel chip was running at 85C 24/7 under stock HSF and still kicking...no melting....mind you its NO ADVISABLE and could potentially cause damage in long term (2+years)....but these days most CPUs are used for only 2-3years

P.S. when i noticed his temps, I got him zalman to keep that stuff in check

Huh, i read somewhere that some part of the chip melts or something in the 100C ish range ... if not, then whys the limit 85C?

This is kinda funny but I'm having the opposite issue. My PC Probe is about 10 degrees lower... But it's strange because coretemp, speedfan, PC Probe, and NVMonitor all have some of the same temps...

SpeedFan's is a load of crap. Go with CoreTemp's reading -- that's usually the most accurate.
The best way to test is to buy some temperature probes of your own and do it manually.

The processor isnt solely made from silicon, there are metal oxides and other substrates in the core, plus various imperfections which will cause issues with heat.
At high temps the expansion of the different materials in the core will cause the core to break down and you get that lovely smell of burning electronics

Core temps are like baking a cake...
That is why you don't up the bake time and reduce the time frame... it damages the contents

Core Temps should always be warmer than the CPU temperature. The cores are what warm the over all CPU sensor. How would a cpu get warmer than the cores that are heating it. The heat exchange has to come from somewhere!

That's what I've been saying from the very first post!!!

You're half right!

The only problem is that the thermal diode in the CPU die has its temperature calculated by the motherboard circuitry, so depending on what algorithm the mobo uses the temperature could be read higher or lower than the die actual temp.
For example my abit board reads higher, which isnt a bad thing, better than reading lower imo!

But back to the main q of the thread deffinatly use core temp/TAT, as the digital on die register is calculated by intels algorithm as opposed to the motherboards.

Danny
