If I recall correctly I got the setup powered but stopped short of actually putting it on my CPU when I couldn't mount it all in a way that would let me contain the condensation with what I had.
Maybe it was pccooling or pccasemods dot com? There was a really strong community forum back then where it was all going down, people were nitrogen cooling their PCs, watercooling was a big deal, and CPU temps of 60c were considered unsustainable.
I still overclock my computers but usually my aim is a silent computer under 60% load, so my goals have changed. Peltiers are not something I see taking over PC cooling even now. You still need the same radiator capacity, the peltier just moves the heat away faster and can get below ambient temps at the CPU.
