Looking at the Heat Sink Requirements for the IDT PES24N3:
http://www.idt.com/products/getDoc.cfm?docID=18446090
It indicates that the chip's normal operating temperature is anywhere between 100 C and 125 C, or 212 F (boiling point) to 257 F.
It can go higher than that, 145 C with no heat sink..
I'd say that if it's hot enough to boil at the low end, then probably just a passive heatsink won't do.
