Hey, I just built my new PC and on Open Hardware Monitor it says that core 3 and 4 are in the 85-95C range at idle. It also shows core 6 as -21C. Any ideas or tips would be greatly appreciated.
Seems like the Monitoring software is not reading the Temperature sensors correctly.
Download and install Ryzen Master and see what it actually shows. Uninstall Open Hardware, temporarily only, before installing Ryzen Master.
