    I just got my 13" rMBP early 2015 yesterday, and i am loving it so far!
    The only thing that has me concerned is that when i installed iStat and Intel Power gadget i noticed that under full CPU load the cpu temp would reach just over 100c before the fan ramping up very slowly to a max of 3000 rpm.

    Is this normal? It seems the MBP has a fan curve set to a max core temp of 100c, is it like this with all MBP's? I know TJ max is 105c for these chips, but it just seems very high. I have tried an SMC reset.

    3000rpm? What is the idle fan speed? In my 15" the rpm range is from 2000-6200rpm.

    Idle fan speed is reported at 0rpm, then it starts up and goes to roughly 1200-1300rpm, before slowly rising to 3000rpm at full load and 100c. 2000-6000 was more the range i was expecting.

    Apple's EFI EC controller is much more conservative in a way that it lets the CPU reach Tjunction before it really ramps up the fan. That's per design so don't worry about it. When it shuts down on you then that's the time you should worry.

    Alright, thanks, that's what i hoped for! I actually prefer it being this way, as it means a lot less fan noise (one of my biggest complaints with Windows computers of different brands). As long as it doesn't damage the chip. I'll go back to enjoying my Macbook again now!
