I'd consider your local temperatures when deciding on cooling, do you have aircon?
any air or basic watercooling is only going to be able to work above ambient temps, so if your room is 50'c, you are going to struggle to get low temps,
and that means overclocking would be a big no no
I have moderate cooling in my room ( the temperature varies 30'-40' C)
will i still need water cooling??
and suppose later I decide to upgrade Fan cooling to Liquid cooling, will that pose any problems?
