Well the title says it all. I'm down to these 3 options. Almost same price in my country. Not plan to oc more than 3,9-4,00 gHz on my i5-4690k. I'm definitely using push-pull configuration regardless the cooler i will get. You can recommend me other solutions for cooling my cpu for less than 60-70euros, but i think these are the best choices in my country(Greece). Only water coolers please. Don't start to mention the hyper 212 evo. I know its good but i want a water cooling solution.
