The CPU Cooler Enermax should be more than enough to keep your Ryzen (TDP 65 Watts) cool under heavy loads. According to Enermax specs that CPU Cooler is designed for Processors rated 230 Watts TDP.
What are the Ryzen temperatures at idle and while under heavy loads (e.g. while playing a game) but not being artificially stressed by using AIDA64 or some other stress related software.
Edit: 03/13 Needed to delete the troubleshooting steps in this reply in which I mistook your CPU Cooler to be an AIO. According to Billy72, Your Air CPU Cooler temps seems to be normal for that type of CPU Cooler.
The Maximum Temperature for your Processor is 95C. So as long as it stays below 85C you are in good shape.
