[rescue] loud fans

[Ryan Thoryk]

I was wondering if anyone here knew how to solve this problem.  My Sun Ultra 2
has extremely loud power supply fans, and I could've sworn they used to be
quieter about a month or so ago (???).  As you know the Ultra 2's have 4 fans,
2 on the left for the RAM and CPU modules, and 2 in the power supply in the
back right.  My SGI Indigo2 is really quiet compared to this machine... 
anyway, is there a way to change the fan speeds, or replace the fans (this
would also be good info for people owning older machines with insanely loud
fans).
