EK Water Blocks - EK-RES X3 Anticyclone Long or Short?

[Circaflex]

I am purchasing an EK X3 Res 400 and noticed it comes with the foam or you can get a nice little EK piece that acts as an anticyclone. I am assuming because this is the larger res i should use the EK Water Blocks - EK-RES X3 Anticyclone Long but i cannot find this to purchase anywhere in the US and i cannot order it from EK unless i purchase more items from their store (something about keeping shipping costs down i need to order more than a certain amount). I am assuming the short one is not too good for this size of res and i should use the long version?




EDIT nevermind I guess it comes with this piece already, this was not noted on PPCs and i couldnt find it easily on EKs site, but once i found an instruction manual it seems this piece comes preinstalled
