It's a new system with Enermax Liqtech II TR4 Watercooling. Nothing is overclocked, standard BIOS settings (auto). When starting Windows 10 I've got temperatures higher than 40° C. When rendering animations it goes to 68° C and GHZ drops 3 to 2 GHZ. System is always loud. Cooler runs at 1500/3000 rpm constantly.
Is this a hardware defect? Or can this be fixed with some good settings?
Screenshots attached (from Ryzen Master). Both idle and rendering.
