Hi All: Just got the new 15" mac book pro and its fan kicks up with not very much load. This is the model with the AMD Radeon R9 M370X. So I first noticed the fans kicking up to max turbo speed when just going around in 3D maps with the CPUs pretty much with no load on them. So it might be relative to the graphics card, but then this weirdness happens... The fans kickup during boot. So just turning the machine on and booting and the fans spin up. After the machine finishes the boot, maybe about 1 minute later in the finder, they finally spin down. My 13" rMBP (2013) never kicks up doing similar things. The only thing to note is I used Migration assistant on my Mac Pro (2010) to create my account on the new 15 mac book and wonder if there might be some account cruft that might be causing this effect? Any ideas on this. Anyone else experiencing very quick-to-fan bursts on their new 15"? I'm probably going to take this back to apple but was hoping to get some feedback/insight from the collective brain trust. Thanks!
