Beginning with the Late-2009 model, upgrading the hard drive in your iMac was no longer as simple as installing the new drive of your choosing.
As we reported on the Rocket Yard, Apple changed the game when it came to hard drive upgrades. In Late 2009 and 2010 models, Apple introduced a different cable for each brand drive that forced users to install the same hard drive brand in order to upgrade.
But with the evolution of modern hard drives, this is becoming harder to accomplish. Fewer and fewer drives can actually still be swapped brand for brand. Since 2009, several of the major hard drive manufacturers have merged companies and technologies.
So thermal pinouts on some drives had started changing and other drives no longer even had the thermal sensor pins to connect to in the first place. Our former recommendation of swapping out brand-for-brand is now outdated, but that doesn’t mean we’re leaving our customers high and dry.
OWC announced today its In-Line Digital Thermal Sensor kits, which makes the brand-for-brand drive swapping a non-issue! With this OWC solution, all the compatibility issues are fixed and you’ll be free to upgrade your iMac with ANY brand 3.5″ SATA hard drive. So not only have we expanded your drive options for updating your iMac, we’ve done so with no software hacks necessary and complete AHT diagnostic compatibility.
That’s not to say that brand-for-brand drive swapping didn’t work. For those who’ve already done a brand-for-brand swap and aren’t experiencing any issues, your iMacs are good to go and safe to operate. But for anyone who is experiencing fan speed issues or for anyone looking to do a drive swap in the future – we recommend the new OWC In-Line Digital Thermal Sensor kit. We even provide helpful instructions with our step-by-step installations videos!
