A few days ago I took apart my laptop to see if my processor was removable. My dad was watching over me and after I removed the heatsink (I think that's what it's called. It's the part connected to the fan and directly above the processor) a small greasy sticker-like thing ripped, half was left on the processor and the other half the bottom of the heatsink. He said that it was processor grease needed to keep my pc from overheating and that I should replace it.

Is this true, or was it something else like a "void warranty if broken seal"?

He's correct, that was the thermal paste (grease).
It's a heat conducting paste.
It helps with the heat transfer from the processor, to the heatsink.

No matter how smooth the processor, and the heatsink look, there are imperfections on the surface.
The paste fills these imperfections, creating more surface area to conduct heat away from the processor.
The more heat removed, the cooler the processor runs, and the longer it lasts.

The paste should be applied as thinly as possible, as too much paste, will have the opposite effect.
