It was working fine all day when I was setting up the 920 and the 980x but after a high load bench I heard a click noise and then I noticed that the 2nd stage was loosing temps fast. So I shut the computer and the Cascade off and let it sit for a day... Today I turned it on as usual but the Second Stage is stuck... It doesn't turn on anymore, just hangs there with first Stage on -41c and nothing happens. When I press Hot Bypass valve I also don't hear it kicking in anymore...
