Believe it or not I had a bad time with this specific model too, I had it replaced and the replacement failed within a week or something aswell. I got credited by PCCG and went with the Hydro series H110i 280mm instead and it's been fine since 9 months. Both times the pump failed, tubes were hot for me too and my pc was switching off when it got too hot. Send it back. I remember at the time the reason we decided to stick with a different model from corsair was because they were both going through different manufacturing so we took a gamble and apparently they do it right. Forgot where and how we found this but it's out there, whoever is making the model you have failed hard IMO.
