Heat Sink & Retention Module Installation
It is highly recommended that only the M-855 Heat sink and fan (Figure 4), designed
for use in the chassis be used. The use of other heat sinks, including those boxed
with CPUs, may damage the M-855.
Make sure that good contact is made between the processors and the heat sinks.
Insufficient contact, incorrect types of heat sinks, fans, or thermal compound used or
improper amount of thermal compound applied on the CPU die can cause the
processors to overheat, which may crash the system.
The Retention Module is used to hold up the weight of the Heat sink and fan.
