New to subaru need advice

[Sunshine2888]

Hi all 

Just purchased a 2000 plate legacy 2.5gx auto with full service history last service being 5000 miles ago which was major one!! Drove home tonight done 80 miles and engine fan was coming on as I was stopping is this normal everytime? And it also seems a little rough idle and pull away isn't great any ideas? 

Thanks for any help

Was the water temp normal? Have you check the coolant? Check it asap.
