I am aware of the dangers of using a peltier, but when I built it I insulated the cpu throughly with vaseline (of course not on the top) to avoid the problem of condensation and right now the system has been running more than a year, sometimes several hours straight at 55mhz with no problems.

Here you can see the vaselined cpu, on the sides, on the bottom and between the pins (that was a pain in the ass, with a brush):

After that I cleaned the top with alcohol prior to applying the thermal glue.

Yes, I finished this build on July 2018, but didn't get around to document it xD
