In order to avoid condensation, is it as simple as making sure the coolant temperature doesn't drop below the ambient temperature? I'm curious because I'd like to create a shroud, or cold-box, to place around my mora, and see if I can drop temps to near-ambient during overclocking, using a standing A/C unit that I have. Though I'm not entirely sure it will prevent condensation all together, because only the mora would be placed in the cold-box, and not the rest of my bench setup. Which means fittings and cpu/gpu blocks would be exposed to higher ambient temperatures than what would be inside the cold-box, right?

Thank you for all the responses!

My idea was to use the A/C unit to drop the temps as close to ambient without getting to ambient or lower. As far as efficiency, it wouldn't exactly be a priority since this wouldn't be a daily driver kind of thing. It would just be used during the 3-5 minutes of benchmarking, depending on what I'm using to benchmark at the time. And at this point, with all the good points and information posted here, I feel like I could probably just run the A/C unit so that it is blasting cold air into the intake fans on the rad, and that may allow me some amount of drop in coolant temp, but most likely wouldn't approach ambient so I wouldn't need to worry too much about condensation. So I guess the question at that point would be, would the drop in coolant temp allow me to push the processor another few hundred megs. I would need to first see how far I can push the processor without the aid of the A/C unit.

I realize going subzero for overclocking is the ideal scenario, but I just don't have the money or equipment to do it. This is the next best thing for me, even if it's a little janky and doesn't net that much more overclocking headroom.
