you should install Hardware Monitor or its free version Temperature Monitor and then have some real numbers. Haswell processors do run hot in laptops. you may at some point want to upgrade to Mavericks 10.9 as I would assume it will have better hardware support and support 'napping.'
I just saw an article comparing the temperatures of the Mac and others but they weren't all using the same processor or of course the same case, and different OS. Windows on a Mac works but has tended to run warmer and the thermal fan control is not as well built into the drivers Apple includes with Boot Camp.
I think you will find that at 50% cpu loads that it does run much warmer and more in the 60-70*C.

I suggest you return it before its too late,
i think Apple did mention that there is a manufacturer defect that is present in only several thousand units and i guess one of those is yours

I am getting 47 degrees celcius in CPU Core 5, and an average of 40 degrees celcius in all the other CPU cores.
All I am running is Safari internet browser (this forum), my gmail account, a site playing a wav file, and TextEdit open, with full lights on and my battery plugged in.
I can feel the heat on the keyboard.
I used to use a previous 15" model of the macbook pro (thicker) and on that I compiled hundreds of thousands of lines code and worked with a simulation of a semantic language model. In addition I watched videos on youtube at 1080p. And not once, I repeat once, did the temperature of this macbook pro increase or go up. It was stone cold 24/7, no matter the charger plugged in or the brightness. This machine was purchased in 2010.
I am not doing any coding, simulations, etc., yet my machine heats up to almost 50 degrees celcius. Now the parts may be designed to handle higher temperatures, but I believe that regardless, running at higher temperatures will degrade the hardware faster.
All I want is to have a nice cold macbook like I had before (I am not gaming, video editing, etc.). Any suggestions? If the retina really runs this high temp, then it should have been advertised it.

Could need an SMC reset. Could also be the fact that it's charging which definitely heats things up more than they would be otherwise. No harm in having someone give it a look though.
