Thanks. Am I endangering my computer by waiting until the fan goes?
I mean, will I have some sort of warning or will it just quietly
overheat and burn up the cpu if I don't do anything and the fan
decides to let go.

Theoretically the CPU will shut down on overtemperature before it fails.
However, the same may not be true of other components in the laptop. I
would clean the fan and if necessary, replace it now.
