And it's been the coldest summer for something like 5 years...

A Peltier cell is just a semiconductor heat pump. It effectively just
reduces the junction-to-heatsink thermal resistance, allowing you (in
theory) to use a less efficient heatsink (or have the CPU run cooler
with the same heatsink. The downside is they they're relatively
inefficient - your power supply will need to supply an extra 3-4A at
12v and you need to dissipate that extra power. Unless you
significantly improve the airflow through the case, you'll probably
find that the internal temperature rises significantly - further
stressing everything except the CPU.
Note that the chip that most needs cooling may not be the CPU - the
big support chips can also run very hot.
