Kiprusoff, pulled before the third period of Game 4, was barely tested by the sleepwalking Sharks, who had only a handful of scoring chances among their 19 shots.
Nilson, added to the Swedish team for the World Cup earlier in the day, scored his second goal of the series on a broken play two minutes after Iginla's short-handed tally.
Conroy added his fifth goal of the postseason midway through the second period when Sharks defenseman Kyle McLaren loafed after a deflection. Conroy sped past him for a two-on-one with Iginla, then beat Nabokov from the slot.
