be that the fan inside the unit is showing wear. The good news is that

replacing the fan is an easy and rewarding task.

I knew my fan was starting to die when it sounded like it was wheezing

during spin-up. The fan, a Sprite model SU2C7, uses sleave bearings,

whose lifespan is determined by the lubricating oil supply in the

bearings. When enough of the oil evaporates, metal will grind against

metal resulting in heat and resistance that cause the fan to quickly

lock-up. Better quality fans use ball-bearings, but Kensington

apparently used the cheapest component available. Even among the models
