Five unanswered goals meant a fifth consecutive win for UNO.
After falling behind in the first period for the first time of the season, UNO answered with a flurry of goals in the second period and pulled away in the third for a 5-1 win over Alaska Fairbanks.
Chayse Primeau and Taylor Ward each scored two goals for the No. 13 Mavericks (5-1-0), who swept a weekend series from the Nanooks (1-3-0). Primeau added a pair of assists for a career-high four points.
UNO outshot the Nanooks 32-20 and scored a pair of power-play goals. Isaiah Saville made 19 saves on 20 Nanook shots, including 17 in a row after Alaska Fairbanks' early goal.
Saville lowered his goals-against average to 1.81, which is second in the NCHC for goalies with at least three starts.
During its torrid start to the season, UNO's offense has been potent. The Mavericks have scored at least three goals and have outshot their opponents in every game.
The Mavs are averaging 30.8 shots per game and have converted on seven power plays through six games.
Ward scored the equalizer with 10:40 remaining in the second period when he scored a one-timer from the right dot on a pass from Tyler Weiss. Weiss assisted on three goals for the Mavs.
Less than eight minutes later, Primeau skated around the crease and backhanded in a goal on a Weiss' rebound to put UNO ahead.
"We weren't happy with our first period," Ward said. "I think that we came out and really pushed the pace there in the second and just sort of played to our identity. We just stuck to the game plan, and it just all worked out. It was good to get rewarded for, what we believe, are doing the right things."
It would prove to be enough for Saville and the Mavs, who killed four power plays.
But UNO wasn't done, pouring on three more goals. Brannon McManus beat the buzzer for a power-play goal on a rush with one second left in the second period.
With an open net, Primeau chipped in another rebound on a Weiss shot, and Ward tacked on a power-play goal with just under 12 minutes remaining.
The Mavs' five-game winning streak is their longest under coach Mike Gabinet, and their first since the 2015-16 team opened the year with six straight wins.
Gabinet said he liked the way his team responded after falling behind.
"It's always nice when the players realize what's bringing them success," the coach said. "They start talking about it and holding each other accountable. You know that you're making progress when that happens."
The Mavericks' season-opening homestand continues with a series against Long Island starting Oct. 29 at 7:07 p.m.
