I used peltier coolers on K6 processors 1M computer years ago. They worked great and lasted about as long as the PCs did. Not long after I bought mine, they disappeared from cooler offerings. I've wondered what became of the tech.

I remember one objection to Peltier coolers in that application is that could possibly cool the CPU below the dew point and cause water condensation, something a fan can't do.

Remember that Peltier coolers don't make heat disappear - they just move it from one side of the cooler to the other, and produce a lot of additional waste heat in the process. There are better ways of transferring heat from a hot IC to a heat sink nowadays - like liquid cooling for really high-performance systems, or capillary-action heat pipes for more typical needs.

They are inefficient and dump a bunch of additional heat into the heatsink that you need to get rid of.

For this we calculate the dew point with 2 sensors and react accordingly in my temperature controller.

I'd really like to try out these better peltiers, our current ones suck. And the fans to remove the heat are huge and loud.
