    I have mid-2010 21.5" iMac (or EMC 2389). My Seagate HDD is part of the Apple recall and I'm interested in using this opportunity to replace the HDD myself to an SSD (Samsung 830 256 Gb). I've been thinking about this for a while but have always stumbled upon the issue of the Apple HDD heat sensor not being compatible with SSDs resulting in the fans maxing out. I know there are software solutions such as SMC Fan Control but they can cost money and do not work in Bootcamp/Windows (which I do use). I've read about people 'short-circuiting' the temp sensor but this sounds a bit wild to me -- opening the iMac is scary enough.

    It is interesting that I only now found out (if I understand what I've read correctly) that there is a near-perfect solution. Apparently the temp sensor used in the optical drive of the iMac can be used with the SSD (and I'm not talking about replacing the optical drive).

    Could someone confirm that this solution indeed works (replacing the stock HDD with SSD) and that one should use similar cable to iMac's existing optical drive temp sensor, in my case this cable?
