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
