Adams is in the middle of the best season of his young career, averaging career highs in points, steals and rebounds per game.
But while, the 24-year-old Kiwi has been overlooked by fans, teammates Paul George (fifth) and Carmelo Anthony (seventh) were in the top 10 frontcourt players in the fan vote.
As usual, the votes threw up a few head-scratchers, with Los Angeles Lakers rookie forward Kyle Kuzma receiving 184,338 votes to sit ninth in the Western Conference frontcourt standings.
A few more surprises came up in the Western Conference guards votes, with San Antonio Spurs backup Manu Ginobili and Lakers rookie Lonzo Ball both featuring in the top 10. However, the two starting guard spots are likely to be filled by two of Stephen Curry, James Harden and Russell Westbrook.
Milwaukee Bucks forward Giannis Antetokounmpo leads all players in fan voting, while Cleveland Cavaliers guard Isaiah Thomas received over 87,000 votes to sit seventh in voting for the Eastern Conference guards, despite having played just 19 minutes this season due to injury.
Fan voting is open until January 16 (NZ time), with the 10 All-Star starters announced on January 19 (NZ time).
