New Build - CPU temp concerns

[Klordane]

Hoping someone here can help a liquid-newb with a question:

My new build is an i7-13700 with a 360mm H150i top-mounted in a NZXT H7 Flow. Everything went together fine and the system has been running perfectly. CoreTemp and iCUE show the CPU package temperature going up and down pretty rapidly when the system is under minor load (like downloading/installing a bunch of stuff). At idle the CPU hovers around 30-35C (coolant temp 27-30). But during these modest loads the CPU goes up and stays around 55-63C, while the liquid temperature stays at 30. The CPU is not overclocked right now.

I know 60C is perfectly safe, but I'm wondering if I should be worried that it's hitting those temps when it's not really doing heavy lifting beyond downloading and installing a mountain of software. 

I cleaned off the stock thermal pad using Arctic cleaning solution and replaced it with Thermal Grizzly Kryonaut paste, and as far as I know the block is correctly installed on the CPU, but as I noted above this is my first time using an AIO. What do you all think?

Thanks in advance!
