I put a brand new 240 mm ut60 at the bottom of the case in a phantom 630 for my kid. When the build was completed, i filled the res with distilled water in order to start the leak testing process. I never even got to turn on the pump, the reservoir emptied out so fast i figured i must have left a port unplugged. After tightening everything again and troubleshooting every connection, it became apparent that the ut60 itself must be leaking, so i removed the pump/res combo mounted to it, and uninstalled the radiator for inspection and testing.I attached a barb and some tubing to the same port i had been using as "in" and, after filling with distilled water, plugged the "out" with my thumb and blew hard through the tubing. I saw three distinct jets of water project out of the rad in different directions, two from the bottom and one from the top, plus a lot of bubbling under the fins in one of the corners. The thing wasn't watertight at all.I looked it over and couldn't see any bent fins, so this didn't appear to be shipping (or user) damage, but rather, a manufacturing problem. I don't know whether it has bad soldering, defective materials, or both. I don't care, either. I bought a premium brand watercooling component, and it failed catastrophically because of bad manufacturing.Now i have to wait for the replacement (not alphacool!) to arrive, and rebuild my loop. The only electronic components that got wet as a result of the ut60's failure were the motors of the fans that sat under it, so i'm hoping there is no damage to my system. The moral of the story is to check every component before putting into your system.Other issues of note, which collectively might have subtracted one star, are the soft material of the screws that come with it, which strip very easily, and the difference in branding/appearance between the photo on outletpc and the actual product. What i received had no branding, with alphacool logo stickers in a separate baggie. While i like the clean look better than manufacturer's logos all over my system, i don't like differences between what i decide to buy and what i actually get.
