Best location I have found for farming Arctic Fur is in Sholazar Basin.
Gorillas located in the Southeastern section of the zone are not hostile so you can pull at your own pace. But, they are close enough to AoE down if you have that capability. Chilled Meat drop off these Gorillas, along with a mass of trash drops. Be sure to have lots of bag space (2 empty bags) available if you choose to farm these for a while. Additionally, if you find yourself filling up, you can visit the nearby villages to sell off the trash items (Frenzyheart Hill for those aligned with the Frenzyheart Tribe; Rainspeaker Canopy for those aligned with The Oracles)
