Amazing value for an all in one liquid cooler. Build quality is top class, overall design is good with a decent length on the tubes to enable you to fit the rad in the roof of the case. The supplied fan works well and isnt too noisy, and the ability to run in push pull is very desirable if you have the space. *NOTE* As we are yet to test the cooling, its difficult to compare this to other coolers, but once this has been done we will update.


Would of been nice to see the Cooler Master logo shine a little more on the CPU block.
