							Mac Pro (Mid 2010) Take Apart — Processor Heatsinks, Dual 172 2010-12-06
First Steps
Open computer, lay it 
down with access side 
facing up, and remove:
• Processor tray
Tools
• ESD wrist strap
• Long-handled, 3 mm 
flathead hex driver
Processor Heatsinks, Dual
Note: This procedure applies to Mac Pro (Mid 2010) dual-processor configurations. For single-
processor configuration, see “Processor Heatsink, Single.”
Important: Mac Pro (Mid 2010) processors require thermal grease for proper operation. Every 
time you remove a processor heatsink, you must replace the thermal grease on the processor 
below it. New grease and alcohol wipes for cleaning off the previous grease are included with 
replacement heatsinks, processors, and processor boards.

Removal
Note: See illustration 
for position of CPU A 
and CPU B heatsinks. 
When processor board is 
installed in computer, CPU 
A heatsink sits toward rear 
of computer and CPU B 
heatsink sits toward front 
of computer.
1 Using hex screwdriver, 
loosen 4 captive 
mounting screws in 
order shown.
2 Holding processor 
tray steady with one 
hand, lift heatsink 
straight up out of 
enclosure.
Reassembly
Important: Do steps 1–3 
with processor REMOVED 
from processor board. 
See “Processor, Dual.”
Every time you remove 
a processor, even for a 
few seconds, cover the 
processor socket with 
a connector cap. Spare 
caps are packed with 
replacement parts.

1 Using alcohol pad 
included with 
replacement part, 
clean off thermal 
grease from 
underside of heatsink 
and top of processor.
2 Using syringe of 
thermal grease 
included with 
replacement part, 
apply narrow bead of 
grease to processor 
chip (raised square on 
top of processor). 
Apply in pattern 
illustrated, using 
approximately 0.2 cc.
Warning: Do not 
apply more grease 
than recommended. 
Grease must not 
overflow into 
processor connector.
3 Reinstall processor.

4 Carefully align holes 
on underside of 
heatsink with 
mounting posts in 
processor board, and 
lower heatsink 
straight down onto 
processor. Double-
check posts to make 
sure heatsink is 
seated properly.
Warning: Use two 
hands to hold 
heatsink by its sides. 
Be careful of heatsink 
fins, as they can be 
sharp. Do not press 
down on the top of 
the heatsink. 
Important: CPU A 
heatsink (rear) and CPU B 
heatsink (front) are 
different parts; they can be 
identified by their 
undersides (see 
illustration). Be sure to 
install the correct heatsink 
on each processor.

5 To position heatsink 
screws, lightly tighten  
them (4 lb.-in. or  
0.452 Nm torque) in 
order shown, using no 
more than two turns 
of driver per screw.
Note: While 
positioning screws, 
keep heatsink level 
by holding it in 
place with one hand. 
Reminder: Hold 
heatsink by its sides. 
Never press down 
on the top of the 
heatsink.
6 To secure heatsink 
to processor, again 
tighten screws (8 lb.- 
in. or 0.904 Nm 
torque) in order 
shown until they are 
“finger tight.” Then 
turn each screw (in 
order shown) 1/4 turn 
more.
