I suspect that those of you who are having overheating problems with the compressor haven't installed the new version of the ifi_aliases.h file. The relayx_fwd and relayx_rev aliases are reversed in the original version of the code, and that makes it highly probable that you've been running the compressor backwards. If the compressor polarity is reversed, it will still compress air, but its internal cooling fan will not work properly. Make sure the light on the Spike supplying power to the compressor is green. If not, either swap the compressor wires or fix the programming using the new version of the header file from IFI.
