Test TjMax Temperature (max allowed CPU T) on your Mac

Post by Steven »

It's highly appreciated if you can run this simple app on your Mac:

on Windows (running Boot Camp) (RECOMMENDED)

1. Download and extract this small (100kb) ZIP file
2. Open cmd, run the following command

Code: Select all

tjMaxTest_win.exe > output.txt

3. Paste here contents of newly created output.txt file.

on OS X (only works with SIP, System Integrity Protection off)

1. Download and extract this small (20kb) ZIP file. There should be 2 files inside (runTest and macsfancontrol.kext)
2. Open Terminal and go to this directory (runTest). After that execute the following commands:

Code: Select all

sudo chown -R root:wheel macsfancontrol.kext
sudo kextload macsfancontrol.kext
./runTest > output.txt
sudo kextunload macsfancontrol.kext
3. Paste here contents of newly created output.txt file.

hi, i am unable to run the test, terminal comes back and says illegal. macbook pro 2009. any advice?
my fans started running noisy just today. CPU Diode is 163.4F Left fan is 3870 rpm, right side 4181. i haven't changed fan speed yet until i find out whether its due to temp.
i have activity monitor running, nothing using up alot of cpu.
recently repaired permissions and freed up 100gb of free space on machine.

is there a manual or instructions for this app???
thanks for any help
