Using TG Pro to Manage Mac Book Pro Temps (and find your max working load)

by

I blogged about opening my Mac Book Pro and removing dust here. Here is a review of the TG Pro software from Tuna Belly Software. Below I show how you can stress test your Mac help find it’s thermal limits (and manage fan speeds with TG Pro).

You can download TG Pro from here: https://www.tunabellysoftware.com/tgpro/

Stress Test your Mac

On OSX

  • Open TG Pro (right).
  • Open 4x terminal windows (blue) for the stress testing tool (yes).
  • Open 1x terminal windows (green) for the top command line task manager.
  • Open Activity Monitor (bottom left)

Once you start the stress testing tool you will need to manually end task the “yes” processes or reboot your Mac.

In each of the (blue) Terminal windows type: yes > /dev/null &

You will need to fire up as many top processes as required (depending on your processor) to get to 100% CPU activity in Activity Monitor.

You will see 4x process ID’s outputted in the blue terminal windows (remember these as you will need the process ID’s to kill the processes). The process ID is also shown in the green windows below. Failing this you can end task processes in Activity Monitor GUI.

With stock cooling profiles (Apple) in action, CPU temps jump to the low 90’s.

I clicked Auto Boost in TG Pro and temps jump down 10c each core.  This was still with the stress test in action.

What will TG Pro – Auto Boost in Idle situations due to CPU temperatures? Instead of High 50ciI am getting Low 40’s. Nice.

TG Pro is awesome software and I use it to auto boost my Mac Book Pro fans post cleaning dust and reapplying thermal paste on my CPU/GPU.  I paid for the software used in this review (this is not a paid review).

Hope this helps someone.
