A SAS Scandinavian Airlines Boeing 737-800, registration LN-RRT performing flight SK-4490 from Oslo to Longyearbyen (Norway), was enroute at FL370 about 30nm southeast of Trondheim (Norway) when the crew decided to turn around and divert to Oslo due to a number of error messages with several computer fans. The aircraft landed safely back in Oslo about 65 minutes after departure.
A replacement Boeing 737-800 registration LN-RCN reached Svalbard Airport with a delay of 2:15 hours.
The occurrence aircraft is still on the ground about 11 hours later.
The airline reported, there was an error message with some fans for computers on board.

The aircraft thus returned to Gardermoen Airport for practical reasons.
