Figure 31. Example of Heat Plate Up with a Heat Sink 

 

 

Installing the VL-HDW-416 Passive Heat Sink 

1.  Apply the Arctic Silver

*

 Thermal Compound (VL-HDW-401) 

 

Apply the thermal compound to the heat plate using the method described on the Arctic 
Silver website - 

http://www.arcticsilver.com/

  

2.  Position the passive heat sink 

 

Using the figure below as a guide, align the five mounting holes of the heat sink with the 
heat plate.  

 

Orient the heat sink fins in the direction of the system airflow to maximize CPU cooling.  

3.  Secure the passive heat sink to the heat plate 

 

Affix the passive heat sink to the heat plate using five M2.5 pan head screws.  

 

Using a torque screwdriver, tighten the screws to 4.0 inch-pounds.
