Check the CPU temperature in the BIOS.
Check the Thermal Specification for the CPU if it is still within the range of operation.
Get your CPU sl number and search in the link below.
If it is much over the range then, check the following:
Check with board manufacturer for CPU compatibility as sometimes CPUs with different SL number are not validated.
Contact the board manufacturer whether they have any bios fix regarding this.
Make sure that you have a PSU Atx Version 2.2 at least. (Intel Boards)
Make sure that the chassis is TAC - Thermally Advantage Chassis
Check for proper aeration in the chassis. (cable)
Re-integrate the cpu with new small amount of thermal paste (clean the cpu before)
Check and test the system out of the chassis and see if it behaves the same way
For Intel boards, there is their own monitoring, unfortunately, i dont have any information for your board.
3 Series and 4 Series (new boards) should use:
Intel Desktop Utilities:
Hope this helps a bit.
