I purchased the Titan one and when installing the CPU water block I am unable to get a propper seal. I tried a different fitting and it still won't seal. I tested it with the psi tester also from bitspower, at it is leaking air. I have yet to put liquid into the system and can't move forward. Since this came with the case, I can't just take it back to the store and now my build is at a hard stop. Please let me know how to proceed and if you can send a replacement CPU waterblock ASAP.
