Now I have a higher capacity more reliable disk, and a very useful iMac.Įxceptions to the general rules of thumb exist. If I had not been able to run a fan control app, I would have had to pay for an expensive unreliable disk every 2 years for the pat 8 years. That 8 year old iMac is still my work iMac which gets used every week day, runs the groups web server, does backups for some critical group services, etc.
I eventually got a special SATA cable from OWC that included a chip that emulated the custom Apple firmware which reported disk temps. There are several, but I was using SSD Fan Control. data to monitor the temperature, and adjust the fans accordingly. Using a 3rd party disk causes that model iMac to send the fans into Overdrive! The solution was a utility that uses the disk's S.M.A.R.T. You either got the Apple branded replacement, and suffered a failure again in a few years, or you used a 3rd party. The disk itself was prone to higher failure rates than other disks. In my case, the Late 2009 27" iMac uses a disk with custom Apple firmware, that provided the disk temperature. But there are situations were it is needed. Using a fan control utility should be the exception and not the rule.

Iv now installed smcfancontrol 2.2.2 and when I change the fan speed they change for around 4 seconds before going back to default. Im Moment funktioniert nur das Anschalten, welches jedesmal bei einem schwarzen Bildschirm und lauten Lüfter endet, und das Ausschalten, durch das Gedrückthalten des An/Ausschalters für 6. I simply right clicked on the fan control 1.2 icon in the OSX Prefferences menu and clicked 'Delete fan control 1.2' and restarted.
