Extending a CPU's lifespan?

So, I'll finally be buying a new CPU in about a week, and I was wondering if replacing the stock cooler with a better one would extend the CPU's lifespan at all by keeping it cooler. Any noticeable difference, or not?

Typically, cooler temperatures do increase lifespan. Stock coolers have come a long way though and if you're not looking to overclock or don't live in a house that is sweltering hot in summer then you probably won't really benefit much in terms of longevity. I like to get aftermarket coolers just because they're quieter. I don't think I've ever really pushed the envelope on my CPU to the point where I would have needed the aftermarket cooler though.
 


At the moment it's 35c...
 


In that case I would personally get an aftermarket cooler. It may or may not extend the lifetime, but the noise is going to be a lot more bearable.
