Compaq presario V200 very hot

I have installed OS of Compaq presario v2000 with windows XP.
In the first step, this installation progress terminated because processor temperature very hot, this is called overheating. And then, i turned off the laptop. I release all laptop casing, with keyboard first and i see that the processor cooler is very dirty, so i take the cooler and fan cooler and clean with the brush.
I plug it back, and the temperature decreases ( normal ).
So i can install OS ( Windows XP SP3 ) until finished.
