Kraig,

You don't need an external transducer and don't want one. You want the
ambient environment of the CPU circuit board, which is reliably reported
by the quartz crystal resonant frequency, assuming it is calibrated.
For this appliation you want to maximize the temperature coefficient, rather
than minimize it, which is the usual practice.

As for knocking about in the steam tunnels, rewind history to circa late
fifties, when some of us installed miles of surplus field-telephone wire in 
the steam tunnels between the student dorms, along with broadcast carrier
transmitters. That 40-watt monster under Alice Lloyd was my contribution.
