A few months back I cleaned the fan on the processor, and the heat sink on
the graphics card. There was a noticeable drop in their temperature.
(Neither had been cleaned in nine years.)

My son had to clean my wife's laptop computer fan when it started
getting noisy. She is not a neat/clean-nick, but keeps her computer
area clean, and it still partially clogged the fan fins after about 3
years. Now it runs nice and cool and quiet.
