Hello OMs,
I purchased an Orion fan OA109AP-11-2TB for my Alpha 8410.
The product details page shows the holes for the screws are 4.22 mm
so I purchased M4x45 machine screws.
The screws fit the motor perfectly, but 4 mm diameter is too large for the 
holes on the rear of the amp.
And 45 mm length seems to be too short.
Does anyone know what are the correct screws to use?
