Well, the system makes a good anchor when the CPU burns up. VERY bad  
idea.

Seriously, go google "Replacing CPU heatsinks" you'll find a lot of  
info, 99% about PCs but in this instance, there's no difference  
between the Mac and the PC.

Remove the heatsink.

Clean the old compound off the CPU, and the correspondign contact area  
of the heatsink; you may need to use a razor blade to scrape it off,  
you may need to use isopropyl on a Q-tip.

place a tiny amount of Arctic Silver in the center of the cpu or the  
heatsink contact area. By timy I mean a blob a < 5 mm in diameter.

Attach heatsink, making sure all four corners are properly secured to  
provide even pressure across the CPU.
