Intel Desktop Board DH55HC Technical Product Specification 
56   
To ensure functionality and reliability, the component is specified for proper operation 
when Case Temperature is maintained at or below the maximum temperature listed in 
Table 31. This is a requirement for sustained power dissipation equal to Thermal 
D
esign Power (TDP is specified as the maximum sustainable power to be dissipated by 
the components). When the component is dissipating less than TDP, the case 
temperature should be below the Maximum Case Temperature. The surface 
temperature at the geometric center of the component corresponds to Case 
Temperature. 
It is important to note that the temperature measurement in the system BIOS is a 
value reported by embedded thermal sensors in the components and does not directly 
correspond to the Maximum Case Temperature. The upper operating limit when 
monitoring this thermal sensor is Tcontrol, as shown in Table 32.
