Cholesterol increases fluidity at low temperatures. Does the function of cholesterol stay the same at warmer temperatures? Also, how exactly does cholesterol increase fluidity? I know it wedges between fatty acids.

No, it has the opposite effect at warmer temperatures. It increases fluidity at cold temperatures by disrupting the great amount of hydrophobic interactions among slow-moving tails.
