Never, unless you remove your heatsink/cooler. Some pastes even benefit from not changing it, as they have a long cure time- AS5 is an example of this.

Stock pastes are often of lower quality and dry out over time. Usually the stuff that costs $10 per syringe never really do. You should only need to replace it if you remove the heatsink.

And for that reason, it's highly suggested that you spend the extra $10-15 for decent TIM.

Apply once, and save you a lot of trouble in the long run. A solid TIM will give you a noticeable decrease in temperature over stock TIM.

Its brand specific,some lasts quite a while while others needs changing every 12 months.


EDIT:

IC Diamond: "We have one system application where we have been running approximately 2 years with no change in thermal performance in a normal office environment."
Found Here

Thermalright Chill Factor: "Life expectancy after use: 12 months"

Depends on whether it is the kind that can dry out over time or not. Just read the directions and instructions for whatever kind you have.

Testimonial: I used AS5 on my desktop, and I don't think I've reapplied TIM for at least 2 years.
