Ryzen 1600x Temperatures

Hello! I am using a ASRock AB350M PRO4 motherboard with an Ryzen 5 1600x CPU. I am using a Noctua NH-L9x65 fan cooler.

 

While idling the temperature fluctuates between 35-50 Celsius and while gaming it got up to about 75-80 Celsius (monitoring it with Ryzen Master software). I checked task manager and it said it was only using 50% performance, but when I stress tested it for 10 minutes at 100% it gives me the same temps. I am concerned that I either need to get a better heat sink or reapply more thermal paste even though I coat a thin layer to 90% of the surface.

 

Does anyone know if these temperatures are nothing to worry about or should I look into buying a new cooling system? I would rather not spend more money if I have to but don't want to destroy the CPU.

 

I currently using the stock settings and not overclocking. Also to ensure airflow wasnt the issue I opened up the side panel of the computer and was reporting the same temperatures.

 

Any help is appreciated!
