One of my Drives died yesterday as well due to heat problem, even Corsair D900 Case with descent cooling was unable to save it.
This is the only disk which was installed into motherboard and second one i have in cooling cartridge from Angel Bird Wings PX1 Company and it stays around 42 c and the one which was unprotected was able to reach 72c in idle mode.
i did send request for warranty already but still waiting for them to respond.
Again i would recommend something like Bird Wings Adapter in order to cool it down .
It works Great!!!!!............
