Yes mate, it is under warranty, they only give them 2000 hrs, but in our experience they typically last five times that! Howver, being a weekend we can't conrtact the suppliers 'til Monday, other than send an email, which I'm going to do next.
It didn't seize-up though, it's liquid cooled and pressurised so that the coolant can't get to the bearings and the casing was barely warm to the touch. It sounded like one of the many silicon-nitride balls has broken up and caused a cascading disintegration of all its little companions. I just got a spanner on it and managed to turn it a little, it sounds like a tin of broken biscuits, which is a very good analogy of what it's become
at least we are never going to be at 30,000ft when something hits the fan (or the fan thingy bursts and hits something else)!
By my reconing, Reg is due back pretty soon.
Keep up the good work mate
