In the last year self contained water cooling kits have gotten more popular. This is mainly due to some users that want the benefit of water cooling but do not want to either custom build a cooling loop or have the money to throw at a custom loop. Enter companies like Corsair with their H series coolers and CoolIT with their A.L.C. series. Today we are looking at the ECO A.L.C. 240 from CoolIT Systems.What is different from the self contained kits we have looked at so far is that the ECO ALC 240 has a 240mm radiator, not a 120mm radiator. The radiator comes with two 120mm 1900 RPM 63 CFM fans, but can support up to four 120mm fans for a push/pull configuration. With more cooling capacity, a bigger radiator and more fan capacity, the ECO ALC 240 could be a very good performer for its $125 price tag.Now the new ECO ALC 240 is just like the ECO ALC 120 in regards to the types of fans and pump/block unit. The only difference is the larger radiator. The ECO ALC 240 is a self-contained, sealed loop CPU water cooler. With the unit being sealed there is no need for the system coolant to be filled or topped off like a custom water cooling loop would require due to water evaporating from the coolant reservoir. This maintenance free operation is also one of the attractions for some users to use self-contained units
