Indoor Temperature Sensor OWC OWCDIDIMACHDD12
The OWC OWCDIDIMACHDD12 in-line digital thermal sensor cable lets you install a third-party SATA drive in compatible iMac models while preserving the original fan control and Apple diagnostics. This wired indoor temperature sensor connects directly to the iMac System Management Controller to provide accurate thermal readings and maintain proper system fan behavior. When used with an OWC Internal HDD DIY Kit (sold separately), it enables replacement of the factory hard drive with up to an 8.0 TB HDD or a high-performance SSD, increasing storage capacity or data speed without disabling the iMac's built-in temperature monitoring.
The inline thermal sensor is a plug-and-play hardware solution that requires no software hacks and is fully compatible with Apple’s diagnostic processes. It maintains correct fan control through the iMac’s System Management Controller, reduces unwanted fan noise caused by unsupported third-party drives, and supports large-capacity HDDs or SSDs when combined with an OWC Internal HDD DIY Kit. The product includes a 27" adhesive tape set for installation convenience.
Install the in-line digital thermal sensor cable inside the iMac following the OWC install video instructions. When replacing the original drive, use an OWC Internal HDD DIY Kit (sold separately) and follow the step-by-step guidance in the install video to connect the sensor to the system and secure the adhesive tape. Verify the connection to the iMac System Management Controller so that the system recognizes the sensor and maintains correct fan control and diagnostics. If you are not confident performing this complex procedure, consider professional installation by certified technicians.
Before attempting installation, watch the OWC install video to assess your skills. Professional installation is recommended for users unsure about performing internal iMac upgrades. OWC provides the install video as the technical support resource for this DIY product and assumes no responsibility for installation damage.
