Occasional spike to 90+ are normal behaviour with these ROGs.
Don't trust those who write they never pass 80-84°C, this might be true only if they play lite games (Overwatch etc.). In that case with some games low temps around 76-82°C are perfectly normal. There are much more demanding games though… e,g. the Rise of the Tomb Raider benchmark etc. Try these 2-3 times in a row and you'll easily see spikes of 92-96°C.
In particular AIDA64 stress test on most of these laptops with i7-8750H (apart a few very lucky users) very often reaches spikes of 92+ but the important thing is that are just spikes, and then the processor sets a lower power consumption limit reducing MHz and temp... e.g. run AIDA64 stress test, in the first seconds can reach up to 96°C then lowers the clock and stabilizes also the temps (e.g. 3300Mhz, max 84°C constantly). This is normal and is ok with these laptops.
