Late question, sorry. What's the maximum operating temperature of the metal frame of the appliance? I've met some that are happy with 70C internal frame temperature, which would be only 10C off the maximum operating temperature of the device. That will limit the cooling capacity of the device. --=20 James Cameron http://quozl.linux.org.au/ --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
