a Noctua nh-d14 will be more than enough if not better than the Corsair h100 in terms of price and performance for hitting a 4.5ghz on IB.

if you own the H100 for free, just use it. there is only a little different performance of h100 compare to dh14.

but if are consider for buying a h100, it is always better for you to get the dh14 or a custom water cooling kit which is almost the same price as h100 and better in term of cooling efficiency.

hope this can clear up your confuse.
