    Hi everyone

    A while ago I installed an OCZ Agility 3 SSD in my 2011 MBP.
    Since then, my device indicates the "hard drive temperature" as 128°C (constantly)... Is something wrong? Clearly, the SSD is not that hot. Did I break a sensor while putting it in or something?

    Thanks for enlightening me! :)

    Just ignore temperatures for an SSD... they don't overheat. The temperature sensor in my OCZ in my desktop has never worked. My Crucial doesn't have a temperature reading at all. So yea... just ignore it.

    I am having the same issue with my corsair force series 3 ssd. It turns out that most ssds don't have a temperature sensor and the null reading given out makes the macbook think your sensor is broken, thus spinning the fan up to max just in case your computer is that hot. I've been looking for a solution for months now and the only thing that I have found is to use smcfancontrol to set rpm parameters based on cpu temperature. It's not perfect but its better than just letting it spin up to 6200 rpm. If anyone else has a better solution, I would love to hear about it.
