Are my 4070 Super temperatures too high?

I've just upgraded to a 4070 Super, and HWiNFO64 gives me three different GPU temperatures, which peaked at the following temps (average was a fair bit lower) while running Control at max settings (RT and DLSS on):

GPU Temperature: 75.1C

GPU Memory Junction Temperature: 78.0C

GPU Hot Spot Temperature: 86.6C

It also tells me that the thermal limit is 84.0C. Should I be concerned that the hot spot temperate is higher than this? And which of the above temperature readings would get used for throttling?
