The North Stars won another at home despite the Hounds' efforts.
Notre Dame's Jakob Breault opened the game's scoring about five minutes into the game, off power play due to a Matthew Fletcher roughing penalty.
Ryan Gil scored his tenth of the year, followed two minutes later by Austin Becker.
The North Stars machine kept rolling in the second period and didn't look back, off goals from captain Cody Spagrud and assistant captain Braydon Buziak.
The third period opened with a fight Notre Dame's Conor Maclean instigated. The scuffle resulted in a total of 31 penalty minutes, 17 of which went to Maclean, while he and Ryan Gil were ejected.
The Hounds couldn't muster many chances thanks to some solid defensive play by the North Stars, and their nine shots in the third period amounted to no goals.
Number 19 was all over the scoresheet, as first star MacGregor Sinclair earned three points, placing him 11th in league scoring.
Humboldt comes to town Tuesday night.
