I have set up several Dell Latitude E6430 / E5430's, with different hard drive configurations, and all appear to have the same issue; the hard drive runs at a constant 118*-122* F. I've tried tweaking several settings, but nothing seems to help. The drive operates at a normal 80* F when booted to Windows or Ubuntu, so it's clearly not a BIOS / Hard Drive issue. And as I have already mentioned, this is consistent across several different systems. I haven't found any other reports of hard drive's overheating, but can't believe that I would be the only one. If you find that you also have this issue, please post a "Me Too" in the comments with as much information about your system as well. HWMonitor Screen Shot: Just to clear up some possible assumptions; I have been successfully building hackint0sh's for about 10 years. I have only recently started messing with Hackbook Pr0's (about 2 years). Initially I was using Chameleon, but decided to switch to Clover when I found Chameleon seemed to have trouble performing certain tasks (like patching the video output for Intel Graphics). While using Chameleon, I was actually manually patching the binary with the outputs of my system to get everything to work as it should (if you have no idea what I'm referring to, it doesn't really matter, so don't even worry about it). The problem with doing this was upgrading. Every time I needed to upgrade the OS, I would need to re-patch the updated kext. Such a pain! In finding that Clover did this rather simply, and that updates would no longer be an issue, I made the switch. Since using Clover, the main things I've had to fight with are; getting the trackpad (which works pretty well (with multi-touch)), bluetooth, and the battery percentage to function properly. But, addressing those things are issues for another time. Shortly after I switched to Clover, I found THIS VERY HELPFUL GUIDE (Thank You VERY MUCH pokenguyen!!!), and tweaked things from there. I probably have several hundred hours in tweaking, and researching, all the configuration settings/options in Clover itself. And although, I don't completely understand everything it can do, I know enough to get a system working as it should. I've just come to an end in trying to address this overheating hard drive issue, which seems to only exist in laptops. The one thing I have absolutely no understanding in, is DSDT...and maybe that's where my issues are. I really wished I understood the code within an aml file, but sadly, I do not. I am very good at learning how to take knowledge from someone else's experience and convert it to something I can apply to my own hardware, but aml files are beyond me. I'm going to post as much information as I can about the system(s) I am using, and would appreciate any suggestions/feedback on how to resolve this Hard Drive temperature issue.
