It's 40 mm square, and quite thin (< 10 mm), from a dead hard  
drive.  At normal indoor temperatures (20-25C), it spins from 100-200  rpm.

I chose 45C for the baseplate temperature so it can be used at any  
ambient temperature I'm likely to encounter.  40C was, I thought,  
just a touch too low for that.

Best  regards,

Charles
