Do the late 2013 MBPr's run cooler than the early 2013?

Do the late 2013 MBPr's run cooler than the early 2013? Read today that someone's computer runs at 30 C idle or near idle. Mine runs 50-60 C typically.

*edited: I am referring to 15"

13" or 15"? My late 2013 13" rMBP idles in the mid 30s, and only feels slightly warm to the touch.

My 15" also is around the mid 30s when idle. Most of the time it's near the 35-39 Celsius mark. During some medium load, it's usually about 40-50 degrees Celsius.

 

[red321red321]

My computer has never ever run in the 30s before.

No, hotter

My early 2013 15" is usually 46-48C when web browsing, according to smcFanControl.

I suspect neither do theirs. You have to take what people report with a bit of a grain of salt unless then specify which program they're using.

I very much suspect people reporting temps in the 30's are using a program like iStatPro. iStatPro does not measure CPU temperature, it measures CPU Heatsink temperature. There are other monitoring programs which only report heatsink temperature too.

Whereas qtx43 is reporting using smcfancontrol, which does report the actual CPU temperature.

To back that up:

at idle I'm getting 46-47C from smcfancontrol and 34C from iStatPro.

Also, software on the Windows side reports high 40s to low 50s at idle.

oh and this on an early 2013 15" rMBP

My Haswell 13" rMBP runs at 46-47 degrees C at iddle, way colder than my old june 2012 13" rMBP. The old one would feel very hot on my lap, the Haswell is a keeper!

You are correct, I was using iStat Pro to report the mid 30's temperature but I didn't know this only calculated the CPU heatsink temperature. That said, here is my smcfancontrol temperature and my iStat one.

Apps currently open are iMessages, Safari, Mail, iTunes, Tweetbot, IntelliJ Idea, iTerm, Activity Monitor, Dropbox, Last.fm, ReadKit, and Gfxcardstatus.

Still getting a 38C report from smcfancontrol. These are my idle temperatures. I'm not doing anything too heavy, and I've just finished watching a doctor who episode.
