Evan sounds like it only addresses boiling but that's not the issue, it's
cooling, and with those high temperatures, the oil is starting to deteriorate
as well, now you're into a whole new list of problems.
Again if you have not read the TEAE article, it gets to the heart of the issue
which is effective cooling and ways to do it.
