Temps are fine for average Joe, but now that it's built I have to look to the next adventure, so why not see how far I can push it, that's all. I am looking to try out TEC's, which is probably where I will end up since I haven't tried that yet, but I would still like to be able to use my chiller if I want too. I designed it to quickly connect to my current loop using QD's, that way i could use it anytime I want without a lot of hassle.
