Kraken X62 High CPU temperature normal?

I have an Kraken X62 water cooling that cools the Ryzen 2700X. When I looked at the temperature in Fortnite MSI Afterburner, I noticed the high temperature about 72 ° C (see picture). The fans are mounted correctly and also blow cool air to the radiator. The voltage from the processor is all on AUTO and the fans are set to perfomance in the CAM software. I ask for help!

72 ° C are completely normal under load

But the processor is certainly offended because it is used for Fortnite. XD
