i fixed it i change the max fan speeds to something a bit faster of a rpm and that seems to fix it   
Im getting a system shutdown and random times. The system logs in Dell osma say  The system board IOH THERMTRIP temperature is outside of range. when i check the impi tool i see most sensors are off how do i re-enable these sensors and how do i see the thermal trip range and change or modify it
