My machine won't regulate processor thermal heat

Hi i'm Leslie,

Ive got a lenovo g580, i3 with 8GB RAM running on Windows 10 (v1511) ,

my main problem is the Processor Thermal.

I tested my machine with the Intel Processor Diagnostic Tool 64bit latest version, managed to pass everything else but failed with the following error :

...

Entering run forever

1 degrees C below maximum

Test Result - FAIL

Expected Greater than 1 degrees below max

Received 1 degrees below max

Test FAILED

Please check your Processor Thermal Solution

...

Kindly help us with a solution for the problem because its been making my machine shut down unsuspectedly without notifying. This has caused instability when i'm working throughout the day.
