Mine never leak, but they did a complete recall whether yours was leaking or not. If anything got damaged by the leakage they replaced that. EK has top notch customer service. It was their first one so it was bound to have some sort of issue. I just asked for $50 reimbursement as I had to disassemble everything and order new thermal paste. They paypal'd me the $50 without question.
A friend had his GPU get killed by leakage, they covered an exact same card.
