OWC In-Line Thermal Sensor (OWCDIDIMACHDD09) is a wired temperature sensor designed specifically for 2009–2010 iMac models to enable installation of third-party SATA drives while preserving proper fan control and system diagnostics. The plug-and-play cable provides a hardware digital thermal sensor interface to the iMac's System Management Controller, avoiding software hacks and maintaining compatibility with Apple's built-in diagnostics.

Advantages

This in-line digital thermal sensor eliminates erroneous fan behavior by supplying accurate drive temperature data to the iMac, allowing third-party HDDs or SSDs to be installed without disrupting fan speed control. The device is easy to install as part of an OWC Internal HDD DIY Kit (sold separately) and supports large-capacity drives up to 8.0 TB or high-speed SSDs when used with the appropriate adapter, while keeping original diagnostic functionality intact.

Suitable for

• 2009–2010 iMac users upgrading or replacing internal SATA hard drives
• Users installing third-party HDDs up to 8.0 TB
• Users installing SSDs via a NewerTech AdaptaDrive or similar adapter
• Technicians performing DIY internal drive upgrades while retaining system fan control
