I have not used the alphacool kit but I have used a couple different versions of XSPC kits. I have the XSPC 750 EX360 kit in all three of my rigs right now and really like them. I have found the kits to be very good and the revision 4 pump in the current kits is really quite good plus the block is rated really good from all of the reviews I have read. It has keep my i5 3570K to about 27c idle and around 50c full load.
With the XSPC coming with everything you need minus the coolant it is really good for beginners but has the quality in the components to make it equally good for experts as well. While I did not get the Alphacool I did read alot of reviews when I was getting my kits and the XSPC really won out and I think it was the best of them.
Thanks, i will go for xpsc then, can u tell me do you have your 3570k oc? or stock?
And which kit si better ? ax? ex? rs? rx?
