[X4U] firmware update creates the fan from hell

[Bob Virzi]

I had to do a firmware roll back once, and it was not pretty.  I forget the
exact steps, but it was pretty close to installing an older version of the
OS and then applying all the updates to get me to the one just before the
one that broke.  I was a half day affair.

I had a problem once with google desktop causing my fan to go berserk.  You
should probably run the system monitor to see what may be running to get the
machine so hot (if it is actually hot).  I find that iStat Nano is also a
great little widget for monitoring temps, fan speeds, etc.  Maybe it will
give you some ideas as to where the problem is.
