Nottingham Panthers coach Corey Neilson said his side were not at their best as they rounded off a perfect weekend in Scotland with a third consecutive win.
Panthers beat Braehead 5-1 on Friday and thrashed Edinburgh 5-0 on Saturday
But they were made to work harder for Sunday's 5-3 victory over Fife Flyers.
Neilson said: "Overall we started slow and struggled to adjust to the ice and rink but in the second period the guys got their act together, moved the puck well and we carried it through."
The result takes Nottingham level on points with Sheffield Steelers at the top of the Elite League standings.
Meanwhile, defenceman Martin Tuma has not fractured his kneecap in the win as was first feared.
He will miss Tuesday's home game against Edinburgh, but should be fit when Panthers host Braehead on Saturday.
