2011 iMac SSD Upgrade

[ispperformance]

I am upgrading my 2011 iMac to a SSD drive, and seen a post somewhere about a temp sensor? Something about the fans will run on high if you do not get a special cable with a temp sensor in it to stick on the SSD?

I am ordering all the stuff I need today to swap the drive, can anyone shed some light on this temp sensor thing for me?

Just put in the drive and run this program. Done.

Set SSD disk to “Auto from Smart” and leave default values.

I use HDD Fan Control. Was recommended when we upgraded the iMac years ago.

you have to make a connexion between pin 11 and 12

Im curious, will the HDD/SSD still correctly rapport the temp via SMART?

Also, OP might be interested in the chosen answer from THIS thread..

yes the temp is ok with smart

Ok, so I installed the new SSD, and installed the fan control software. Where is the software getting the temp reading for the SSD? System related? Also, what is the usual temps and fan speeds for the 2011 iMac? Just want to make sure that the software is the option for the long run, I don't mind buying the temp sensor if its a better route to go.

Set the speed/temp for whatever you're comfortable with.

I have mine fairly aggressive so the fans are at 95% at 140F and that's about as hot as it ever gets. The cpu is fine at 175 but I like to keep the psu cool as well.

Fwiw the hdd fan seems to make the most noise with the least contribution to cooling so maybe cap it at 75%.

Press the “SMART” button on the left.
Done deal.

SMART value is read by the SSD internally. It literally has a thermometer (die) built in.

What OSX are you using with HDD Fan Control. I am using it on High Sierra but wasn't sure if it worked on Mohave or Catalina.

High Sierra too. It's the highest version my iMac will support.

High Sierra too. It's the highest version my iMac will support.

FYI: I have an iMac 11,1 late 2009 (Samsung SSD installed) running High Sierra. I heard solid reports of success with macOS Mojave Patcher so converting to Mojave soon. That is the reason I asked about HDD Fan Control.

Macs Fan Control does the job and it does well
It works on High Sierra, Mojave and Catalina
