Reg MKII's and cooling fans.

[John Lussmyer <Cougar@CasaDelGato.Com>]

Ok, I can get some little 1.38" muffin fans for 89c each, though I may get 
the 2"x5/8" blower for $2.25 instead (it'll be easier to mount).

Now I have a choice on hooking these up.
A) Add Yet Another set of wires to the mess, so I can power the fans and 
only have them come on when the charger is connected. (Use a relay off the 
AC to connect the fans to the 12v supply)

B) Use some 75c thermostats to switch the fans on when the regs get 
hot.  The problem is the ony cheap thermostats I can find turn on at 135 
deg F, and they are almost as big as the heat sink.

C) Figure out if I can easily make SOMETHING that would let me hook them up 
to the MKII (Internal Load) regs so they come on when the reg starts 
dissipating heat.  There are external load connectors on the reg, but I 
don't know if hooking up one of these little fans to them would cause a 
problem.
