What *can* happen with thermal grease is over time the conductivity  
of the grease does start to fail. If you removed the heat sink from  
the CPU then you will have disturbed the heat sink -> grease -> CPU  
transition, so i recommend you reapply.

There is a lot to say about how to do this, so the best thing to do  
is to point to a website with more information:

(These guides are for Intel processors, but once you understand the  
important points you can apply them to any processor).

Top tips:

1. Don't use too much grease

2. Make sure all exposed areas are covered evenly with a credit card  
or similar plastic card to spread it.

3. Make sure both surfaces are clean of grease before you begin.

4. Once you place the heatsink  on the the CPU don't remove it again!
