Peltier VS Water Cooling?

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
I was wanting to know what difference I would see in a Petier<sp> and
a water cooled system?

What temp drop do each give you over a standard HSF?
Anyone had any personal experience with this?
Also, I've built 6 systems in my life, so considering that, how hard
would it be to do either setup? peltier v water cooling?

thanks people!!

Hi Pedro.
Something for you to read here, if it helps

With just a water cooling system, there is no danger of the
processor or socket going below ambient temperature. The result
is there is no danger of condensation and the resultant corrosion.

When using a Peltier or a phase change (refrigeration) system,
the temperature can be driven below ambient. The processor and
socket area must be protected from condensation. Even with the
best of efforts, there could be corrosion in less than one year.

Peltier also wastes a tremendous amount of energy. Some
Peltier coolers draw 200W of electricity. This doesn't make
a Peltier cooler a very practical solution for everyday

Since the Peltier pumps heat from one side of the device, to
the other, the heat must be removed from the back of the Peltier
for it to work well. You can see in this sample product, that the
Peltier is actually using a water cooling system, to carry away
the waste heat (the 200W mentioned above).

A water cooling system, by comparison, only uses energy
for the water pump and for the fan attached to the radiator.
That is much more efficient and a much more reasonable solution
for overclocking, than Peltier or phase change. Overclocking
on water means you can run it that way all the time, with less
of an impact on the electric bill.

This is an example of the insulation used to prevent condensation.
Some people use grease-like materials and neoprene covers, to
insulate the area around the processor.

This is an example of placing Neoprene around the processor.
Some people use several pieces of material, each trimmed to
a different shape.

If you look in the cooling section of these forums, there
are six subsections. You will find all you need to know about
the various cooling options in those subsections:

   Air Cooling
   Liquid Cooling
   T.E.C Cooling (Peltier)
   Chilled Liquid
   Vapor Phase Change (refrigeration systems)
   Dry Ice (CO2) and Liquid Nitrogen

Versus neither of them, both will cost more and have little
to no benefit unless you were grossly overclocking.  Versus
neither, both will also increase noise at the expensive of
time and money to implement.

Are you doing extreme overclocking?  If not, the answer is
use neither, they would only be detrimental.  There are
other severe environments where a system might *need* exotic
cooling, but these situations being the exception rather
than the rule, one would think the situation would be
mentioned as a primary criteria in cooling type selection.

Depends on exactly what you get.
It's a bit like asking "rollerblades or skateboard" what
speed will a random kid be able to go if we dont' know where
he's using them.

"In general", a properly sized peltier and support cooling
(which may also include water cooling of the peltier hot
plate) can allow going below freezing,   while water will
always keep the temp a little above the ambient temp of the
radiator (the room temp).  

The lower temp possible with a peltier  can be seen as good
or bad, since going below the frost point  anywhere means
you need to insulate either the peltier-cooled parts or
everything around them to keep moisture from causing
problems.  They also use a lot of power, or rather, waste it
unless you are trying for some experimental overclocking
contest entry which couldn't hope to run well long-term.
Cooling mad-overclocked parts is not as difficult as keeping
the motherboard power circuit cool as it was not designed to
dissipate that kind of heat long term.  For the short-term
it might manage ok, so winning a contest is the best
application, or just a hobby you feel like doing for the
practice rather than a reasonable cooling solution on a

Do you need either of these?  What is your goal?
Most people would be better off with a high-end traditional
air-cooled heatsink, large/thick fan, and well designed
chassis cooling subsystem.

Given your experience level, if you "had" to do one or the
other the water cooling would be a better first project, but
if you have never tried high-end air cooled heatsinks, have
not used them and hit a heat limit when trying to
excessively overclock, the more important step is to get
this extreme overclocking experience first.

Just a slightly different slant on this, but Peltier devices do have
their applications in areas other than over-clocking - for example in
locations with very high ambient temperatures where air conditioning
isn't an option. The object of the exercise isn't to get temperatures
down to or even approaching zero, but to get them down to those that
might be expected in a normal environment.

Peltier devices allows the interior of a system box to be maintained at
25C, whilst the box is sat in a 40C room...

...  of course, see what I wrote above.

The importance might be seen as designing forward instead of
backwards, know and consider the design requirements towards
choosing the cooling method rather than randomly picking
between two methods.
