From what I've seen on many forums, the S6 is known to be the worst for overheating. We've concluded (based on logic, but NOT backed with any data!) that this is due to its small size compared to the S6 Edge and compatible Note Series phones. It may be that its smaller surface area doesn't allow the heat to dissipate as quickly. The S7 apparently addressed the issue by adding dedicated hardware to help dissipate the heat (cooling pipe or something??).
Again, this is all speculation, but it certainly seems to be true that the S6 overheats more often than other Gear VR compatible phones.
