Easy fix: Macs Fan Control. Free, runs great on bootcamp (at least with Win 7/8, no 10 support yet....), and fully controllable settings. Nearly perfect software.
I have run WIn7 Pro and Win10 Pro via BootCamp and they did not get hot at all. Seldom hear the fan in my MBPro 15 Retina. I run Win7 Pro for years now on all my macs. No heat problem here.
