BeforeyouinstalltheCoolingSolutionAssemblyreplacetheThermalPadswith
ThermalGrease.
16. RemovetheThermalPadsfromtheCoolingSolutionAssemblysurfaces.
17. ApplythermalgreasetotheCPUandNorthbridgeModules.Useapproximately
onequarterofthecontentsofthegreasesyringetothetopofthebothasshown
