Samsung sells a VR headset for Galaxy S7 whitch is making the phone verry hot and stops after 15 minutes because of overheating. I designed an adaptor to fit a cpu heat sink (50 x 50 x 24mm high). You must add a 1mm silicone thermal pad between heat sink and phone. The adaptor clips on the phone swkeezing gently the pad without glue or paste. The pad transfer the heat and protect the phone from scratching. I could use the VR set without stop for more than 1 hour an never stops. I did not try for more than 90 min. The screen side will eventually get hot anyways.
