While browsing the owc site, I came across the instructional videos. I found out they have a video on how to upgrade the original hard drive. On that video they show a replacement SATA power cable which fixes the sensor problem, so the fans don't spin up.
I browsed the site but could not find where they sell this cable.
Check it out!
