Hey i am completely NOOOB to these CPU watercoolers to the regular sinks with the heat adsorbing fins and the fans. I am thinking of getting one and stepping up little by introducing some water to my system 
The question i just want to ask do they require any maintance work over-time mainly with the liquid?
Do they have a good life span?
Do they loose there cooling momentum (I don’t know if that the right word to use?)
Your opinion of the Pro's and Con's of using a CPU watercooler, or would you stick with a normal sink?
Hope i aint thinking to much into it
thanks
