It's my opinion about it. ;)
If the best closed loop cooler (240mm) radiator is the Water 2.0 Extreme and that's only 38mm then this might be the new king. Assuming the fin density is there and that fans are able get air through them.
Yep, it would go quite nicely with LEGEND's build, based on the profile picture. Also even nicer with a Fractal Design case. Silverstone EA'd the water cooling business :P
Silverstone has 2 new CPU coolers on their website. The TD02 and TD03. Personally I think the TD02 will be the new king of 240mm radiator closed loop cooling. It's 45mm thick!
