Processor Support
3.5.2.11 Intel ® OS Guard
Protects the operating system (OS) from applications that have been tampered with or hacked
by preventing an attack from being executed from application memory. Intel
protects the OS from malware by blocking application access to critical OS vectors.

3.6 Processor Heat Sink

Two types of heat sinks are included in the compute module package.
On CPU 1 – 1U Standard Cu/Al 91.5mm x 91.5mm Heat Sink (Rear Heat Sink)

On CPU 2 – 1U Standard Ex-Al 91.5mm x 91.5mm Heat Sink (Front Heat Sink)

Warning: The two heat sinks are NOT interchangeable.
This heat sink is designed for optimal cooling and performance. To achieve better cooling
performance, you must properly attach the heat sink bottom base with TIM (thermal interface
material). ShinEtsu* G-751 or 7783D or Honeywell* PCM45F TIM is recommended. The
mechanical performance of the heat sink must satisfy mechanical requirement of the
processor.
Note: The passive heat sink is Intel standard thermal solution for 1U/2U rack chassis.
