SP 120s. The SP120Ls that the H100i comes with are really really loud.

SP120Ls are similar to SP120s that you can buy, difference being they have grey rotors, don't come with the rings and have no vibration isolating mounts. If you are looking for better performance, though, look elsewhere. The SP120Ls spin 400 RPM faster than even the performance edition of the regular SP120 and that's why they're louder but the aerodynamic side of things like blade shape and stuff is the same for both. If they are run at the same speed the normal SP120 can still be quieter due to the vibration isolating mounts, but I don't think it matters much seeing as the heavy radiator will absorb most of the vibration. Just pick whatever looks best I'd say.
