I am assuming that the cpu that you are using is fully compatible with the board and it is on the board compatibility list.
First thing to do is to:
check for latest bios release notes and if needed update to the latest version:
2) Where are you reading the temperature from?
3) Are you using any tools? If yes which one
a) If it is an intel motherboard, try the tool from Intel to read the temperature
Note: This cpu can go up to 71.4C (even 5c more i will say).
If you have temperature higher than 75C using the Intel Desktop Control Center, then it can be due to any of these:
a) bad integration
b) PSU not ATXv2.2
c) Chassis is not TAC (Thermally Advantage Chassis)
d) Test the system out of the chassis if needed
Hope this may help you.
The maximum temperature for your processor is 74.1°C, if your current temperature is below that one, this means that your processor is running within the normal specifications, you can check your processor features here:
In the case that the processor goes beyond the maximum temperature it will automatically shuts down the system to avoid any damage. In case you have overheating problems, please check the following URL:
