Id say its worth it. It is by far the best cooler I have ever used.
Tho from reading the forum here, it seems to be kind of hit and miss quality wise. The good thing about that is Corsair stands behind their products, so they would fix you up if you had an issue. I havent used a CM 212, think a TRUE, or a NH-D14 would be better then that? If so, then the H100 easily sucks up volts better then they did. If I had a little cpu like you guys had, Id run that biznatch at 5ghz+ if the chip was willing..
If you really want the goods, then replace those crap corsair fans with some 120x38mm finger maulers, and you have the next best thing to a custom loop
