No Peltiers don't need big heatsinks - that's a misconconception and a
design flaw. They aren't popular since they were initially introduced
prior to the Pentium1 (several patents were filed); however, passive
cooling in those days was more than adequate. Passive cooling needs big
heatsinks - even with big fans - with today's CPUs. You will still
need to put in enough case fans to exhaust the heat your pulling off.
The biggest mistrake poeple make is not setting the heat pump voltage
properly or choosing the wrong heat pump. Many people erroneously think
that in order to cool the CPU (overclocked or not) you need to chill it.
You don't . You just need to drop and regulate the temp to 15-20
degrees celsius - and thus no condensation. These devices are extremely
efficient and effective at cooling. I have had great success with them
in the past. - not just for CPUs, but also for a variety of scientific
instrumentation.

I don't use them anymore simply because it is easy and relatively
inexpensive to pick up a faster CPU, mobo, and/or graphics card.
Although I do a bit of gaming, mostly my PC runs office apps, www
browsing, a few DVDs, and some video/image editing, I only see a small
difference real world performance in overclocking. With 3GHz CPUs, most
tasks are done before I can reach for the mouse - anything that may take
a few minutes just means that I can check my email or go take a ****
while I'm waiting. Going faster the 100-150fps in an OPENGL shooter at
1600x1200x32 full quality, FSAA 4x, etc, is just a bunch of weenies
saying "mine's faster!" So what? I used to have the same discussions
with motor heads over whose car was faster. Big whoop.

Didn't I read somewhere that peltiers cause condensation around the CPU? I'm
pretty sure I did.

I think if you investigate you will find that most overclockers who use
Peltiers these days (there is nothing new about their use in
overclocking) water-cool them. With a Peltier you're dissipating the
heat generated by the CPU and the additional waste heat generated by the
Peltier. If you can't cool the CPU without the Peltier then you don't
have a chance in Hell of cooling the CPU _with_ the Peltier. And
Peltiers introduce their own complications.

can water cooling cause corrosion, cause I will be water cooling my
gf3 card as a test, then i will use my radeon 9700 pro AIW if the out
come is good
