I just replaced my Macbook Pro's Mid 2012 HDD with a Samsung 850 EVO SSD. The performance is great and I am very happy, but I noticed that the fan seems to run faster. It is not a drastic change, but it is noticeable. I have downloaded iStat Menus, the Exhaust of the fan is 2000 rpm and the Temperature is a bit over 50°. Is that normal and is there any chance I did something wrong while replacing the HDD? I am running Yosemite and I did a SMC reset.
Have a look at Controlling the fan speed in Mac models after an SSD upgrade. Extracted from that article:
- Download the app “smcFanControl“
- Install smcFanControl into your Applications folder
- Open Automator
- Create “New Application”
- Go to Utilities > “Run Shell Script” and delete the word “Cat”
- Copy the following code into the Shell Script:
/applications/smcfancontrol.app/Contents/resources/smc -k F1Mx -w 1770
- Test the Shell Script by clicking on “Run” and your fan should stop running at full speed
- Save the application to your SSD as “maxfanadjustment”
- Open System Preferences, go to Users & Groups, the tab for Login Items
- Click the “+” to add a new application and navigate to the Automator file you just created and add it.
Don't download smcFanControl, infection "PUA.OSX.InstallCore" found in the .dmg file.
