I have the H115i, and I can confirm that it runs smoothly on P500A: There are several images of this combination on Google / Reddit.

It's a very good product, no CPU temperature problems (even with overclocking) and very low noise level. It is also very easy to mount (but be careful to remove the old thermal paste).

Another advantage is that it leaves space above the graphics card, which is crucial for optimal airflow with latest generation cards (2080TI/3080FU etc).

According to the manufacturer, this cooling should not extend over the RAM slot.
