> Not true.  The precisely machined surfaces of the bearing face shrink
towards the center of mass for the outer and inner races as the temperature
drops.  These bearings are designed for correct clearances for most
efficient operation to be achieved at the normal operating temperature of
the drive which is usually close to 50deg. Centigrade.They will function
correctly up to 90deg. Centigrade or higher.
They are made of a precision bronze alloy and the metal will experience
enough shrinkage at - 0deg. Centigrade for a stuck bearing to free itself
for an indeterminate period of time.
The read/write head will also be slightly farther away from the platter but
still within designed operating tolerance.
You have to chill the drive long enough so that all of the internal
components reach a stable low temperature.  15 to 20 minutes will only give
you a chilled outer casing unless you have access to a commercial cryo-chill
facility.
