Gap pad/Putty pad identification and location
Follow the information in this section to identify their shape, location, and orientation of the various gap pads and putty pads used in SD665-N V3.
Installation Guidelines for gap pad and putty pad
For the gap pad and putty pad used in SD665-N V3, see the following sections:
Attention
There are two types of thermal pad: putty pad and gap pad.
Gap pad—Replace gap pad if it is damaged or missing.
Putty pad— When replacing components, always replace putty pads with new ones.
Do not use expired putty pad. Check the expiry date on putty pad package. If the putty pads are expired, acquire new ones to properly replace them.
