and yes, Puma fan bearings would appear to be a regular failing from
the number I get in for repair

The fan has been making a lot of rattly noises over the past few months
although this seems to have gone away recently. (Possibly not a ood
thing?!) Is it possible this is a fan issue?

Do Pumas need regular servicing? I'm always wary of inviting someone in
who could charge me hundreds for something I don't understand.
