Marlen, that sounds peculiar -- it shouldn't be running that hot, not even close. It maybe a bad batch or a broken processor/gpu so the others have to work extra hard... not sure.
I have the 15 inch Retina as well, but the one model below yours I believe. 2.3 ghz / 8mb / 1 gig gpu. So yours should be running as cool or cooler (depending on activities).
Most stores (I got mine from best buy) allow up to 30 days to return. I'm hoping you kept receipt. They won't reinburse you in money, but give you store credit for same price. I would try to get another. Same model, or maybe the model I have. I been really happy with mine, the heat was a little strange - but first time MacBook Pro and apparently they are known to get hotter then most laptops. The aluminium cover attracts the heat from the processors, that's why it's often hot to touch (but it shouldn't be running near 100C , like I said 75-85 C under heavy use is my prediction). Final Cut Pro is a pretty hefty video editing software if I remember corretly from college. Haven't tried it but I still wouldn't think that computer would go above 65 C running that and a couple other programs.
I got the 1 year warranty, it's 150 dollars but the rep. told me it covers basically everything, including overheating and water damage, etc. 2 years was 350 (ugh)..You have to do this within 30 days. Maybe if you exchange for a different one, get a 1 year warranty too.
If it's been within 30 days, and you have receipt, definitely go to store and tell them your experiences - it's getting really hot and system freezes. They should let you exchange it receipt provided.
Is the room where your computer hot? what temperature program are you running? Depending on the program , mine says different things. Right now - I just got this browser open and itunes and smcfancontrol reads 41C avg. temp at 2150rpms.
Where as Temperature Gauge reads 36 - a 5 degree difference.
Best of luck.
