after editing about 78 canon 5d markII files through lr3, it was time to export. nothing else running and the fans completely silent until i hit okay. fans were a' blarin' and istat put the temps at 197 Fahrenheit at their highest. It sped through the 78 files, fans dropped down to dead silent again and my temperature is now around 124 Fahrenheit with only firefox running. . . so, my question is was all of that normal? i know the fans kick in to cool it, but is a temperature of nearly 200 degrees damaging to my computer. I'll be using LR3 almost everyday, if that matters or not. Thanks again!

That's fine. The CPU can withstand temps of up to about 220F, and if it gets high enough to cause damage, it will shut itself off. You shouldn't have issues with that though.
Thank you very much. got worried when it sky rocketed. although i must say, even though it got so hot and so loud, it was worth it. I've never seen anything process so much so fast. Thanks again!
Looking up the proc on the intel website gets 100degC (212degF) as maximum Tjunction. Tj is the limit for the actual die. I would be curious exactly how the temp monitors in the MBP are calibrated i.e. what does istat saying 100degC mean in relation to Tj. Usually in electronics Tj is a calculated value. One controls a thermal sink to a given temperature and then there is a temperature rise to the hot spot of the die determined by power in the device and how good the thermal sinking is from the die to the (usually metal) sink. The actual temp rise is governed by many mechanical factors like how it is soldered, the thermal resistance of the packaging on the die and the attach to the sink...... etc etc......
It is possible to have a thermal monitor built into the die...... does anyone know if Intel does this??
Lastly...... 100degC is hopefully a bit conservative. Many electronic circuits really will function to more like 125degC so I don't worry so much about damage.....
FWIW.... I have seen istat hit in the 90s on my 15" MBP...... For now I will put my faith in Apple and see how the machine does over the first year.....
dont know what 200 is in celcius,or farenheit[i forget] but mine peaks at about 90-95 when gaming or editing raw images in iphoto,or even exporting gets a bit hot too up to 80,ive heard that if its new spotlight takes a while to index and may account for heat,if it starts to smell bad and smoke pours out,go for replacement,otherwise,just monitor with usual progs like fan control or istat etc,should be fine.

This also shows where most of the heat is generated an vented. Pic is a little blurry but it's late and I'm going to bed. I'll post a clean one tomorrow, hottest point is 86.8 in the middle

during exporting tiffs from Capture One Pro i was landing on mid 60s, photoshop brought it down to 58ish, and general browsing is steady at 39/40.
SC2 though.... now that fella will bring me up to 80/85 :O while idling with nothing running stays under 30.
I'll wait a few more days for the paste to settle after reappliacation and jog the cpus a bit with yes /dev to see where Im at under stress.

Heatpipe & Thermal Compound
Interesting heat dispersion even with the heatsink design. Another option if your a DIY'er is to replace the thermal compound on the cpu/gpu. Great writeup can be found in this post
