CPU Core Temp. reached 95°C overclocking Intel i4790k to 4500MHz, is this okay?

[Mogu]

Boosted CPU to 4500MHz and core voltage was 1.250v. Core Temp. got to max 95°C, when I started stress test prima95 + in-game Rocket League + streamed to twitch + opened a lot of apps (OBS, Streamlabs, Steam, Temp apps) + 5-6 pages in browser. (CPU usage was %100, game kept crashing every 2-3 minute)

This is my rig:

I had to pull it down to 4400MHz and lower voltage to 1.200 to stabilize. Now when I ran the stress test + everything at these values, i got max 87°C.

Without stress test, temperature is much lower around 70°C or so. I wanna make it 4500MHz, would it be okay to go with it?

The 4790K already goes up to 4.4GHz with Speedstep alone. Without any manual overclocking.

If you run into voltage trouble and heat problems at 4.5 already your chip either ain't a good pick for OCing or there's something wrong with your system (cooling) to begin with.
