However, that temperature sensor cable has but two wires (one light and one dark) and only 6 pin sockets. Western Digital drives have an 8 pin connection for plugging the temperature sensor cable into. The second most common reason that the fans on the iMac go haywire is when replacing a Western Digital drive with another Western Digital drive. I installed a Western Digital drive exactly like the old drive and my fans are still going nuts! The LCD temperature sensor cable is located here on the motherboard: If the Optical Drive and/or CPU fan shows the fans spinning over 2,000rpm – then it is the LCD sensor cable that most likely isn’t fully seated. If the hard drive fan is spinning over 2,000rpm, chances are the cable isn’t fully seated at one end or the other (or you’ve installed a Western Digital drive – see the next section of the article). If your fans are each in the 1,000rpm range (give or take a couple hundred) everything is running normally.
If you install the iStat widget you can determine easily which fans are running faster than normal and in turn, identify which sensor is giving you problems. The LCD sensor controls the optical and CPU fans. The hard drive sensor controls-you guessed it-the hard drive fan. The LCD sensor and the hard drive sensor control different fans inside the iMac. Luckily you don’t have to rip your iMac back apart to diagnose whether your LCD sensor is the problem. If that sensor does not get plugged back in during the re-assembly process, the iMac’s fans will run at high speeds even if the hard drive’s sensor cable is plugged in correctly. During the process of removing the iMac’s LCD to get at the hard drive, the LCD temperature sensor is removed from the logic board. The most popular reason for the spinning fans is that one of the temperature sensors was not seated fully (or at all) during re-assembly. So why are the fans in my iMac spinning wildly after my hard drive upgrade? We’re proud to announce that after some extensive testing with every current 3.5″ HDD we carry, the swapping of brand for brand is still 100% completely valid in those models. This would make any previous hybrid partitioning irrelevant anyway.After seeing an uptick in reports of out of control fan speeds in 20 iMacs, we decided to revisit our suggestion of the same brand for brand swapping of the main hard drive in those models to verify that our information was still current. Since you only want Windows on your Mac, then you can use the USB Windows installer to erase your entire drive before installing Windows. High Sierra and newer versions of macOS no longer hybrid partition a drive when creating a ExFAT partition. I should point out this is not the only way to acquire the Windows Support Software. There is a option on the Boot Camp Assistant menu bar for downloading the Window Support Software. The best way to insure you are using the correct Windows Support Software is to use the Boot Camp Assistant installed on the same Mac that is going to run Windows 10. The image shows the WindowsSupport folder was copied instead, which is incorrect.Ī Windows installation can fail if the wrong Window Support Software is being use.
You are suppose to copy the contents of the WindowsSupport folder to the root folder of the flash drive containing the Windows 10 installation files. In other words, I would expect to see the path shown below. There should not be a WindowsSupport folder.
The $WinPEDriver$ folder should be in the root folder. Your link contains the image shown below.
The end goal of this process is to get windows only running on my mac, I do not want a Mac OS partition due to the limited hard drive space I have available, which is why I am attempting to install the whole thing from a bootable USB instead of bootcamp. I have downloaded the Windows 10 ISO repeatedly from Microsoft and am sure it is not corrupt and do not have any idea what is going on. ( ) Despite all of my efforts I cannot get the installer to recognize my computers hard drive. I also manually used fdisk to ensure a hybrid MBR partition scheme is not used, as detailed here. The drive is 256GB total in size and I have a windows partition formatted to exFat to try to allow the installer to detect it. I am running into much the same problem detailed at
The issue I am running into is no disks are displayed, and if I try to go into the WindowsSupport directory I added to the USB drive after downloading from bootcamp while it does have a AppleSSD64 driver it does not appear to function or allow the OS to detect the drive. The USB boots up just fine, and allows me to get to the part of the windows installation where it asks me to select which disk to install the OS onto.
I have been trying to install Windows 10 via a bootable USB on my Macbook pro (2016 running Mac OS High Sierra 10.13.6) for some time now, but I continue to run into issues.
