Since the game caps at 40% cdr from items, everything beyond that threshold indirectly increases the costs for further cdr items, as you pay for a stat you don't need anymore (that's why I don't like how Riot puts CDR on every other item nowafays).

Frozen Heart (20) + Iceborn (20) + Spirit Visage (10) = 50% CDR.
