Okay I have a MBPR 2015 6100. So right now I have 10.11 but even before i update even on 10.10.3 it was running hot now my question is i had it under Scaled `More Spaces` @ 1680*1050, Having it on this res. Will it make it run it hotter then normal ?? Its just I've had other MBP R 2014 models and they never ran this hot before .... Also 10.11 runs so much better then 10.10.3 ... Thanks :cool:
 
I don't feel like my 2015 13" rMBP runs hot. I'm running at 1680x1050 resolution as well.
 
I am running my 2015 13" rMBP @ 1920x1200 (custom) and it doest not run hot, so 1680x1050 should be fine.
 
Typically the 13" retina does not run hot, high temps are generally associated with the 15" being a owner & user of the 15" MacBook Pro forever; Over the years the 15" has frequently struggled with it`s thermals, especially when an external display is connected as the dGPU switches on as default, internal temperatures soar;
  • Elevate the rear, aluminium passive coolers generally work best (I use RainDesign`s mStand & iLap)
  • Increase base fan RPM to 3K or as much as you are comfortable with (MacsFanControl or SMC Fan Control)
  • Swap out Chrome for Chrome Canary as it`s way more optimised for OS X and will extend battery run time, reduce thermals
  • Swap out VLC for Movist as again it`s a reduced load on CPU/GPU
  • Uninstall or block Flash
  • Powered coolers are very much a "mixed bag" when it comes to Mac portables, you need one that has a high capacity (100 CFM minimum) and preferably a large single fan, this can help to keep the 15" internal fans below 4K which for many is good enough as often it`s this point and beyond where the fans become intrusive. Don't expect a powered cooler impact internal temperatures, beyond a couple of degrees
  • Cleaning the cooling system is also an option, depending on which year, the complexity varies. A good an indication as any is the environment.
  • Replacing the thermal paste has been hit & miss, some with very positive results, some with no improvement over stock. Personally I would only do this on a Mac Portable that was either very old, or one that I can confirm was definitely running hotter than stock.
The key to a quiet life with a 15" MacBook Pro is several incremental changes that do add up to reduce thermals. From my experience over the years if your going to push a 15" hard the fans are going to max out fast, with associated noise. If your using it with a moderate load life can be made cooler & quieter. For the most part the 15" MBP runs hot as that`s how Apple designed it, the trade of for form over, function, thin & light...

The old adage still applies; it`s easier to keep a system cool, than cool-down an already hot machine. This being said it`s not strictly necessary, equally it`s nice to know that there are options for reducing temperature out there :apple: My own 2014 13" rarely if ever heats up or spools up the fan. Remember if your running 10.11 its Beta, so it may impact the thermals of the system.
