Selecting T for condensing fluid

[eureeca]

In cooling distillate off a column, is there a disadvantage to making a condensing fluid in the tube side of a shell and tube too cool? Assume melting points of the condensing material are below the Temp, so nothing is solidifying.

Thanks for the input!

"Too cool?" Cracked tube sheets, pulling material backward into the condenser (air plus flammables = boom), cutting reflux ratio (wasted distillation step) --- you can run with it from here.
