Processor Heatsinks for
2.8 and 3.0 GHz Processors
This procedure applies to 2.8 GHz and 3.0 GHz congurations of the Mac Pro (Early 2008). For the
3.2 GHz conguration, see the procedure “Processor Heatsinks for 3.2 GHz Processors.”
Note: The heatsink for 2.8 GHz and 3.0 GHz processors requires thermal grease for proper
operation. Every time you remove the processor heatsink, you must replace the thermal
grease. New grease and alcohol wipes for cleaning o the previous grease are included with
replacement processors and logic boards. Instructions for applying the grease are included with
this procedure. Note that replacement processor heatsinks come with the grease already applied.
Tools
The only tool required for this procedure is a long-handled, magnetized 3 mm athead hex
screwdriver.
