Welcome to PCHF
The motherboard temp does seem high, although with that program you may have selected the wrong temperature sensor to monitor. Usually the motherboard will be between 25-35 deg and your
CPU, if it's cooled correctly shouldn't really go above 55 deg. Run your PC with the case off for a while to see if that brings the temps down.
You should check that your
CPU heatsink and fan are seated correctly and if you are happy that they are, maybe you want to consider changing up to a more powerful/effective heatsink and fan.
