I noticed when I purchased the Core i5, 2.6GHz model, my temps always hovered around 40-60 deg C even when under load. The fans almost NEVER came on even running Handbrake. Switching to the Core i7 3.0GHz model, I noticed I'm regularly hovering in the upper 90s, sometimes hitting 103-105 deg C according to smcFanControl. The fans rev up and the laptop does get hotter then the Core i5 model but nothing compared to my older Macbook Pros. I'm wondering, for users who has the rMBP, what's your average CPU temps? On a good side, no image retention.
