What is the point in buying an air cooled THEN upgrading to water cooled when they can be had for the same price
air cooled
I see you did not answer this point.

I doubt you can install a water cooling system for £3, and in fact I would not even bother buying a pump that cheap.
Remember that this is my opinion, if you have a different opinion that's fine, but personally I prefer air cooled
I did not say you could install a cooling system for £3. Yes it is your opinion and having reread all your other posts with opinions I will not be replying again to this one.
