Question Good Temps

In general I like to keep my CPUs below 70C and GPUs below 80C.
Sometimes stock GPUs will get into the low 80's. That's OK.

Intel only gives a Tcase spec on that CPU.....67.4C.....but that's not the core temperature......so you can't go by this. The core temp generally can go quite a bit higher than Tcase.

For intel chips, core temperatures below 80°C are recommended.
Above 85°C is not recommended.

If I am not mistaken the TJunction Max temp for the 3470S is 103°C - but my source is limited.
Max temp for RX 570 from my understanding is around 75°C - so keep below 70°C

You can see the Intel temp guide here https://forums.tomshardware.com/threads/intel-temperature-guide.1488337/ ( thank you @CompuTronix )
Tcase is only a factory measurement on the Integrated Heat Spreader that users cannot measure themselves so is not an effective reference point as already stated - this appears on all 6th gen and earlier intel specifications.
