The Best SSD Fan Control Alternatives for Quieter iMacs
iMac users who have upgraded their systems with third-party hard drives or SSDs often encounter a common frustration: an excessively loud hard drive fan. This occurs because Appleās fan management relies on temperature data from the SMC system, which typically collects information from external sensors or proprietary internal hard drive temperature readings. When an original drive is replaced, the SMC can lose its temperature monitoring capability, leading to the fan running at full speed. While SSD Fan Control has been a go-to solution, allowing users to manually configure fan speeds and override the automatic system, it's worth exploring other robust SSD Fan Control alternative options that offer similar control and advanced features.
