Hi,

sorry for the late answer. I have the same laptop and have experienced much better cooling/heat-performance so that the laptop no longer throttles during gaming by doing the following:

• turn off CPU-turbo by setting max performance to 99% in power options
• under-volting CPU using Intel Extreme Tuning Utility (XTU), currently set at -0.125V but depends on your CPU
• under-volting GPU using MSI Afterburner, check thread mentioned below for profiles you can download
• set a frame-cap of 60 fps using RivaTuner
• head-modded bottom of laptop case underneath the fans by drilling holes and gluing on dust-filters
• used copper-tape to remove gap between fans and heat-sinks inside laptop
• using a notebook-cooler with fans positioned to blow air straight at the fans located inside the laptop

Turning off CPU turbo and under-volting CPU/GPU is the least work and have big impact on heat-development.

The following thread has more good information on all the steps mentioned above:
