The difference of the rpm is negligible, and you can always change the fans if you like (more rpm or silent ones), but the h100i is old at this point and the tubing may have been degraded in the box like mine did and the cover cracked (luckily not leakage)after a year and then I got the H100i GTX which is basically the same as H100i v2. The radiator, the static pressure and the overall performance are better. If the prices are comparable go for the H100i v2. But be aware that the v2 radiator is bigger and maybe harder to fit or not compatible with your case, so check the dimensions before buying. also the tubing is very stiff due to the braided tubes and you need to not have obstructions in your case.
