There are a few options you can take to lower the operating temperatures.
You can try undervolting your CPU. I have my G752VT running on a -140 mV undervolt, and it is perfectly fine and stable with a significant drop in temperatures from stock voltage.
You can limit your processor to 99% which will limit the CPU clock to ~2.5GHz and, again, drop the temperature significantly, but also with a drop in performance(I have seen a 4-10fps drop in CPU-bound tests in 3D Mark when testing).
You can add an external laptop cooler. I use one from time to time for some games, and I have seen a 4-8 degree Celsius drop in temps in some games like Mechwarrior Online, which tend to make my laptop run pretty hot. Most of the time it doesn't really do much, just a degree or two difference. I had it as a leftover from a previous laptop.
And finally you can drop the temperature of your room. Maybe kick that AC down a few degrees and hope it helps.
