Message was edited by: overkil6 Late 2009 iMac, Mac OS X (10.6. Has anyone come across this in the past and if so what was the solution to getting a quieter iMac? NB: I've already tried the SMC and PRAM resets. I would like to be able to set the max speed but if this is resorting to a firmware controlled setting I am not certain there is a software solution to this. My question is, are there any other options available to me? I know SMC Fan Control is out there but it only allows you to set the min fax speed. Other than the fan the system runs fine - just loud to the point of annoying. They said that in order to fix it I would need to replace the logic board (ballpark cost of $900). I ran a system diagnostics but it came back as normal however the retailer states that 'AST-105 finds HDD proximity sensor error. 2) Tried the HDD in a new iMac and the fans on that ran at max. What the tired: 1) Tried a new hard drive and the fan still ran at max. They said that it appears that both the HDD temp sensor (integrated) isn't reporting the temp properly AND that the logic board could also be the issue. I took it to an Authorized Apple retailer for support (it's out of warranty). Thus providing the maximum cooling it can, this should be below the maximum operating temperature for your drive.All, I have a late 2009 iMac where the HDD fan is constantly running. This is the temperature that the fan will have reached its maximum speed of 6000rpm. This is the HDD Temperature that the HDD Fan will start increasing its speed from, reaching maximum speed at value specified with “Temperature that Fan Speed is at maximum”. Temperature that Fan Speed will start to increase from enclosures have internal fans, especially devices with multiple hard drives. You may want to increase this to provide extra constant cooling to your drive, but note this will increase the fan noise. SSDs can use traditional HDD interfaces and form factors, or newer interfaces and form factors that exploit specific advantages of the flash memory in SSDs. Note: Hard Disk Drives (HDD) produce sound because of their spinning parts. Now both 'Macs Fan Control' and also 'smcFanControl' can't control the fans anymore and the. This was a near-perfect solution until I upgrade my system to macOS Sierra. The fan has a hardware low limit of 1000rpm, and cannot go slower than this, for most users this should be the setting you use. To solve this issue, I installed a software called 'Macs Fan Control' that can read out the temperature from the SMART status of the drive and control the fan speed itself. What you are generally trying to achieve is to reach the max fan speed of 6000rpm, about 5C below the max operating temperature for your drive.įor when the fan starts to increase we would recommend setting this about 5-10C above normal idle HDD temperature. This shows the higher the temperature, the faster the fan. The graph on the preference pane shows the fan speed to temperature relationship, temperature along the bottom axis, fan speed up the side. We would only recommend changing settings if you have a drive for which they are not suitable, or you wish to have the fan running more, or less than the defaults provide. So for most users you should leave the defaults in place. We have done lots of testing to find the best defaults to suit most drives and situations, and will continue to improve the defaults in updates if necessary. ‘HDD Fan Control Preference Pane’ Default Settings
