SSD Fan Control

What SSD Fan Control is
SSD Fan Control is a free macOS utility for noisy hard-drive fans in iMacs fitted with third-party hard disks or solid-state drives. It includes an application for monitoring and controlling fans, plus a background daemon that resumes management if the SMC resets. Users can override automatic control and set fan speed manually, or choose SMART mode for third-party hard disks. The product lists SMART temperature information. The latest listed version is 2.13, dated October 31st 2013; that release fixes SMART temperature readings for Samsung 830/840 SSDs and possibly other SSDs. The page states compatibility with macOS 10.13 High Sierra and lists OS X 10.8 Mountain Lion support as an earlier addition. Installation requires downloading the package and running an installer that reboots the iMac. If the app fails after an operating-system upgrade, the page advises trying an SMC reset, with reinstallation possibly required.
