hi, your guy who got problem with the macbook pro / mbp retina temperature, your guys can using an app called "TG PRO" combine with my settings preference to set the fan speed. It will cool down your mac when need. FIRST, download 3 file bellow.

Unzip then install TG Pro, then use the second app, you know what to do... THEN put this 3rd file named "com.tunabellysoftware.tgpro.plist" to this path, this is my setting for TG Pro, i spend a lot of time for optimize it so this setting problably is the best settings for TG pro, you don't need to set anything, just put that file .plist in this path : /Users/[YOUR USERNAME]/Library/Preferences/ If after all step above, your Mac will auto set fan speeds when it need it, and send notification to you when you mac temperature goes too hot, you are good to go If not, you just delete my file .plist then restart the app :) Maybe my setting is optimize for MBP retina late 2013 but not efficient with your mac. IF YOU DONT NEED THE NOTIFICATION FEATURE, you can download an app called "Macs Fan Control" from CrystallDEA, set fan speed base on PECI CPU (46 - 56 Celcius) and you also good to go :)
