Titolo: The Liquid Of Choice ?

A question that has been on my mind for some time now. What is the best
liquid to use in cooling a chip? There are several different properties
one would need to look for when saying, “Yes that one is the best”.
Every one knows that when constructing a heat sink or a *water* block
the best material is copper, good heat conduction and relatively small
price, and non toxic.  Now what about a liquid, most people I’ve seen go
with water, cheap (Free?), non toxic.  How ever a downfall of water
rests in the fact that most if not all life is basted on H2O, so you
might get little things growing in your system. You could add some
chemicals to kill them, this raises the toxic level and we are going for
the best.
So what liquid has:
     The best heat transfer (What we are ultimately going for)
     The least toxins in its final form [After all additives] (We need
to be safe, especially with a open ended system where evaporation could
take place)
     The least cost / The most availability (Hey I’m a college student)
     The least likely hood of freezing (Lets assume we can get that
cold)
     The least likely hood of corroding other components. (If it eats
your pump what good is it)
My vote goes to plain simple Ethyl Alcohol for a closed system.
Possibly Hydrogen Peroxide, but I might be a little worried about the
warning on the label “Keep away from light and HEAT.” Could heat
possibly cause it to breakdown in to Hydrogen and/or Oxygen?  BOOOOOM?

Fluorinert is the proper family. It is designed not to damage electronics,
even if it contacts live circuitry.
It is probably just a wee bit expensive, and not available at the local auto
parts store. (I saw it used to cool a $US20M sensor package in the
laboratory.)
But, hey, if you wan the best...

    Just a wee?? Maybe it depends on your difintiontion of wee bit.  Fluorinert
isn't something college student would want to pay for his computer.  For that
cost, you can buy an unoverclocked PC with the clock speed same or greater than
the goal speed he is trying to get from current processor.

how bout r12 or r121 same stuff they use in your car

There is just no way to beat a water / propylene glycol mixture for forced
convective cooling a CPU in the - 55 C to 50 C temperature range and
pressures near atmospheric pressure.  All this other discussion is just
wheel spinning.

I cast my vote for the low tox engine coolant stuff. Think about it, it's
designed to conduct heat, kill growing things (algae) and to run in an
aluminum/latex eviroment (the rad and the rubber hoses) so should be safe
for anything you wish to run it through. The fumes won't kill you (the few
there are) but you may want to run it in a closed system anyway.

I think flourinert was $500 a gallon when the liquid nitrogen cooler was
built.

   I don't know... with a specific heat of .26, it would heat up much more
quickly than water, lowering the rate at which you would be able to
extract heat from the CPU.

  Aw, come on, maybe they'll come up with an allow of mercury that won't
go solid at -38. : )
  (on that topic, didn't the Russians use molten metal in some of their
subs for heat transfer?)

  Yeah.  I know.  It was a joke. : )
