Turns out different programs report wildly different values for temperatures.
Things like iStat Pro and Temperature Monitor report values in line with what I reported earlier.
smcFanControl reports ~102 degrees C under 100% load.
Temperate Gauge Pro reports an average of 91 degrees C under 100% load.
Which are correct? I don't know. Some of this may be apps like iStat Pro and Temperature Monitor reporting on the "proximity," which I take to mean the sensor next to the heat sink, versus the temperature on the die itself. Without an understanding of what's being measured and how that intersects with recommended tolerances, this discussion is somewhat pointless. But it's been pointless for 5 pages now...
Yeah I've noticed the various programs reporting different....I think it was iStat Pro I had (it was a demo) that specified if it was showing the die temp, or proximity temp while another didn't specify but both widgets did show semi-accurate readings proximity wise. Either way gamers have used cooling pads for a while now and while I have one I don't really need it unless I want to be "nice" to my rMBP or if I'm working from my bed where hot heat shouldn't be blowing into blankets and what not (I use a breakfast in bed table and cooling pad 😀 Hard drives and capture deck sit right next to it, yes I'm single haha). Either way I've done some pretty insane rendering from 3 programs at once just because I could and it didn't kill my computer, I did it on my old MacBook Pro too and it always ran wayyyy hotter then my rMBP. Maybe heat wears down parts faster but seeing as the RAM in this thing is soddered its not built to last 20 years, I mean its going to last me a long time but in 3-5 years I'll probably end up with a with a real workstation and my rMBP will be doing less heavy lifting. I always like to have a desktop and a laptop but right now I am using just my rMBP because Mac Pro options weren't looking too nice 4 months ago and I can't really afford it (or fully justify it) yet. I think allot of these concerns are a bit over worry some.
