For 2600K sandy bridge, which would be expected to give better OC's (lower temps)? There looks to be about a $30 difference between them, that doesn't bother me as they are both ~$100 so I consider the price delta a wash. Mostly interested in performance and noise. The H100 uses fans for the rad, so I have to imagine the noise is comparable (unless I put the H100 into a push-pull setup which would then use a total of 4 fans, that would presumably be "louder" than the NH-C14). FWIW I have an ABS Black Pearl which has 2x120mm fan mount at the top which I would attach the H100 radiators (unless anyone here knows this to be a bad idea?). That said, I've always considered these Corsair self-contained water-cooling things to be sorta gimmickie, that is until I saw the H100. So which would be preferred for high-end OC'ing with a 2600K? Edit: Update - I decided to go with both the H100 and the NH-D14, will test them out and see which I like most in terms of OC'ing performance and noise, whichever I like the least will be put to use in my HTPC build.
