i just used ptct to cool down lol
bryiscool, and I also tryed blocking the water exit so it can cool down more, and well... In the starts works well, but after a while, it is so hot that the water can't hold and starts turning into steam instantly, and can't cool down, so that's all the answer to your question.
You can try it your self, block all steam exit, and after a time, it would be hard to cooldown the steam, but maybe in the future I'll fix it.
The cooler cant hold so much steam at the same time, it would be so hot and with high pressure.
one question, why does it have steam exits thats just wasting the water instead of putting it into the cooler to be more efficient
