CoolIT Eliminator and Freezone CPU Coolers Review
 

These two all-in-one water cooling units from CoolIT provide plug and play performance cooling with help of several TEC elements to keep CPU load temperatures down. We stress test the Eliminator and Freezone models on an overclocked Intel processors to see how they stack up against the competition.

the condensation seems troubling. eventhough it only formed with the case open, it's no guarantee it might not happen under certain circumstances with a closed case.

it only happened with case open + idle system + at maximum performance setting;

as you can see from the dBA reading, you don't want to have it running at max performance all the time, not good for the ears, as soon as you throttle it back, the Pelts use less energy, less risk for condensation, you work at your PC, every small load will increase temp, no condensation, closed case = forced airflow front>back, less change for condensation.

It all depends on humidity level in the area of use. It's called or similar to pipe sweating - http://www.wisegeek.com/what-is-pipe-sweating.htm

If you are in hot and humid climate; running at max level with ATX case that has a large screen side panel might have a problem. Naturally, operating such system in North America other than the State of Florida in summer, likelihood might be less.
