Hi panpete, just want to reassure you that everything looks normal - the temps you posted up are quite low and nothing to worry about at all. With the temps you posted, when you hear the fans working it is because they are doing their job well.
It's always a good idea to monitor the temperatures of your components, but you really don't need to worry unless anything hits 80+ and it seems as though everything is currently working well and being sufficiently cooled

Be sure not to put your laptop on anything like a cushion that will act as insulation.
