I put in a turkey yesterday for a cousin's Thanksgiving dinner and after an hour I had issues with my HM and probes. I believe my Gravity feed was alot hotter then the 325°F setpoint, as my door warped Grease deflector spot weld broke, yikes. Anyways, my HM was supper hot also. When my temps are below 300, the HM stays cool, but it can and we'll get very hot if the temperature does increase. I stuffed my cavity as much as I could without compressing it, as I still have 4 boxes of insolation available to use if I needed it.
