I live in west Texas where it can get very hot (100 F) and I just got my CPU, but not the other parts. Is it possible my heat sink paste on the fan will melt before I get the other parts?

NO nothing will melt, heat sink paste is already melted and its job is just to transfer heat between the cpu and heatsink. As for the heatsink itself, aluminoum melts at 660c or 1220 F so your fine there as well.

100 F might cause your cpu to throttle due to overheating but it should not overheat too much.
 


You make me want to leave a heatsink outside in the sun to see what it does :). I have some stock coolers with the stock thermal paste on them.

 
Even sitting in the sun it would only get like 150F. Nothing would happen to the heatsink itself, though you'd want to take off the plastic + fan. Thermal paste is made to handle much higher temps during operation so nothing would happen there either, other than it drying out.
