I've been hearing about liquid cooling for a computer. Is liquid cooling better than air cooling? If so, why is it better? Is liquid cooling for all computers ? Do only gamers use liquid cooling? Why aren't computers manufactured with liquid cooling? My new computer was bought in Sept.2005 Can I have someone add liquid cooling to an OEM (Compaq Presario)computer bought at a retail store, while it is under warranty? With my last computer= the hard drive & power supply burned up, and I never saw the problem coming. Now we are worried.
