'''***Step by Step Illustrated Guide'''*** [br] | | These are easy to follow instructions for replacing the plastic stays on the northbridge heatsink in a Mac Pro 4,1 & 5,1 computer with single CPU. These instructions show best practices. [br] | The northbridge heatsink is held in place with spring-loaded plastic stays. The stays are subjected to high temperatures, and after a few years they become brittle and break off. Even machines 4 and 5 years old showed brittle and broken stays. Since these machines are now approachingover 10 years old, you can safely assume that they plastic stays are either already broken or are about to break. If these break off and the heatsink moves away from the surface of the chip, the chip will overheat, fail and take your processor tray with it. This is a strongly recommended replacement for all Mac Pro 4,1 and 5,1 machines. |
