Would my loop freeze in -15? - Page 2

While the motion of the water will prevent the entire loop from freezing, ice will form in places and it could cause permanent damage to your WC gear. This is much like how a flowing river usually freezes over except for a small part in the winter.
Excellent answer!

Plus, if the RAD is mounted to the outside of the case it would become like a brick of ice due to the small tubes in the RAD trying to transfer heat.

He would need to run with the arctic glycol coolant mixture in his loop. The arctic glycols can keep the loop running down to -50. However, the condensation issue would be the next thing to account for.

I run my loop with a 1-gallon glass pickle jar. In the winter, the jar sits up next to the outside window glass. With the cold glass and the draft of the window, I do not need to place the glass jar oustide for extra cooling power.

is there any risk to break the pump if the liquid freezes and there's no flow in the loop?
Will the pump overheat or something? I mean, it will try to push though the frozen liquid...

condensation would not be an issue. The air has to be warmer then the loop for that to happen. Which it wouldn't be. Since the ambient temp would be -15, he would have to cool the loop colder then that to get condensation, at which point the condensation wouldn't be water, it would just form frost. so unless he is using a TEC it wouldn't be an issue.
