Figure 14: Replacing the Heat Sink
Step 9
Using the syringe of thermal grease provided with replacement CPUs and servers, add 2 cubic centimeters of
thermal grease to the top of the CPU where it will contact the heat sink. Use the pattern shown. This should
require half the contents of the syringe.

Note
Cisco UCS B260 M4 and B460 M4 Blade Server Installation and Service Note for Servers with E7 v3 and E7 v2 CPUs
The thermal grease has very specific thermal properties. Thermal grease from other sources should
not be substituted because it may lead to damage.
CPU spares come with two syringes of thermal grease; one with a blue cap and one with a red cap.
The syringe with the blue cap is used with this server.
