s about GPU Overclocking

Hi. I'm just starting out with overclocking and want to make sure I understand before proceeding. Right now I'm using Unigine Heaven for benchmarking, and my system details are:
CPU: i7 4790
GPU: EVGA 1070 ti Reference
RAM: 16GB DDR3 @ 1600mhz
PSU: 500w Power Supply (Dell XPS 8700 stock)
Without any overclocking and pushing the fan curve to 70%, my GPU temperatures are around 80-84%. Is this typical or safe? If not, should I skip overclocking or go underclocking instead?
Also, is it safe to experience voltage or temperature dips? I often hit those limits briefly and they come back down (see graphs here: https://prnt.sc/oh18nk https://prnt.sc/oh1867).
EDIT: I reached these limits even without overclocking, sorry.
Regarding my GPU voltage, how much should I increase it? I'm a bit worried about raising it further since my power supply is only 500w and I don't want to risk overheating.

I wouldn't increase the clock speed of a 1070ti reference board using an OEM PSU.
The blower cooler doesn't provide much room for temperature management, and the standard PSU might struggle.

That's exactly what I was concerned about. I also have another PSU, but I'm unsure of its quality. It isn't modular, so I won't need all the cables, which would make it a cluttered bundle. It's a Thermaltake TR2 500w.

That Thermaltake isn't up to the job either.
It's a lower-end 80+ unit.
