Fairbanks is in middle between of two mountain ranges while Barrow is about 300 miles of flats away from the mountain range and are on the ocean coast.
Sure there is a difference, especially on warm days by almost a 30 degrees difference. The cold in Barrow stays around a lot longer due it's longitude. Just take a look.
Barrow - Climatological Data - Barrow
Fairbanks - Climatological Data - Fairbanks International Airport
What's better to compare is between Vancouver, BC and The Dalles, Oregon with both near large body of water and similar elevation.
