Surface Temperature Measurement Points; Surface Temperature Measurement Points And Standard Values - Fujitsu MPF3XXXAT Product Manual

(4) Ambient temperature
The temperature conditions for a disk drive mounted in a cabinet refer to the ambient
temperature at a point 3 cm from the disk drive. Pay attention to the air flow to prevent the
DE surface temperature from exceeding 60°C.
Provide air circulation in the cabinet such that the PCA side, in particular, receives sufficient
cooling. To check the cooling efficiency, measure the surface temperatures of the DE.
Regardless of the ambient temperature, this surface temperature must meet the standards listed
in Table 3.1. Figure 3.5 shows the temperature measurement point.
