Question CPU overheating?

[xyz7]

Hi,
I have new build with CPU i7 9700K and motherboard Gigabyte Z390 UD with graphics Gigabyte GeForce GTX 1650 OC 4GB and 16GB memory.
I'm not using this PC for gaming or overclocking, just for personal use and 3D modeling - not professional.
When I render in Keyshot some model, temperature of CPU raises up to 90+ °C. When rendering is over it drops immediately for 40 °C and then still goes down to about 40 - 45 °C - which is average temperature of CPU.
Is this okay?
Tnx

My i9-9900K is overclocked by PCI bus at 125Mhz, XTU Banckmar 3200, running all cores at 4875MHz, cache multiplier x37, all cores multiplier x39 (PCI bus 125 Mhz) so it is very cold, under windows, 39 °C, liquid cooler Kraken X62. Under XTU long running benchmarking max remp is 90 °C, so comparing to your stock temp, I whould recommend replace cooler system and paste with more efficient one (bigger more effective, aero coll 125W etc, to have a reserved capacity in heat dissipation)

It seems the problem was in power options.
I changed maximum processor state from 100% to 95% and now when I run software Keyshot is temp not raising above 60 °C and when I'm rendering is the same temp.
The fans are on silent mode.
