Hello there. Searching the web I found a thousand of apps that do this but no one does every thing asked in the subject. Is there any app (possibily and preferably FREE) that does all those things? And btw, what's the max heat and fan speed that a Macbook PRO (2018 15" i7 16gb ram and 512ssd) should have? Thanks and have a nice day!!!
MacBook Pro 15”, macOS 10.13
The System Management Controller SMC built into your Mac already sets fan speeds based on measured temperatures inside your Mac in a feedback loop. It the SMC crashes, the fans have fail-safe Hardware that sends them to maximum speed in seconds. If the CPU temperature gets dangerously high, your Mac will do an uncontrolled power-down to avoid damage.
Temperatures of the hottest components of under 100 degrees C are not a cause for concern.
This is NOT a job for a computer owner, and is not a job for third party software. Worrying about internal temperature is an unnecessary distraction.
Forget about this and get your creative work done. Now that you have a Macintosh, we are expecting great things from you!
Hi, thank for your reply! Yes, I'm pretty happy with my new Mac but I'm worried about it for this reason: I came from a late 2013 mbp 13" with 8 GB ram and I've never ever noticed so high heat there. In my new Mac I run the same software version (ableton Live 9) and the same os (macos high Sierra) as in the old one. I noticed high temperature over the touch bar area and fans going crazy with a very low Cpu usage (only 3 Midi tracks and some real time modulation), issues that in the old one were not. So, I was wondering why and if is there something that overload. It should also be the Gpu switch as I found searching the web, but I want to be sure about that. So, there is an app for monitoring those things?
Your new 15-in MacBook Pro has Dual Graphics. The Integrated graphics uses much less power and will be is used by default, as long as:
1) you are Not using an external display AND
2) you set it that way in System Preferences > Energy Saver AND
3) The Applications you use to don't arbitrarily turn on the Discrete Graphics chip. Chrome is a known resource hog that turns on Discrete graphics for no particular reason.
I am not familiar with what Ableton Live does about Graphics use, but perhaps the developer could advise you.
The external display is wired up to the Discrete Graphics processor. If that is the way you use your Mac, you will generate more heat than your old Mac (that did not have a discrete graphics chip, or two much larger screens).
Your Mac was designed to remove the excessive heat by increasing the fan speed to move more air. The fans speed is based on measured temperatures inside your Mac. It is designed to take care of itself.
If you wish, you can use a third-party App to increase the minimum fan speed. You can not defeat your Mac's built-in ability to automatically increase the fan speeds when the measured temperature increases.
I use a second display with Live. Now I'm waiting for an answer from the Ableton support.... You have any other advice for me?
One way to reduce the amount of heat generated by the external graphics is to use DisplayPort family displays over "Legacy" display such as HDMI. "legacy" displays continue to re-draw every pixel on the screen every 60th second. This generates a lot of heat, mostly for nothing. That is what CRT displays used to require.
DipslayPort family displays only send data when the screen changes. If the screen is unchanged, the link goes nearly quiet, and thereby generates less heat in the computer.
