![]() ![]() Hopefully the Apple Silicon MBPs will be way better on this front. Honestly, my experience with this MBP has been poor, the thermal management just isn't there regardless of what specific component is pushing it too hard. Here's a screengrab of TB plugged in left vs right side. I can confirm that swapping sides the TB is plugged, almost instantly affects temperatures between the left and right sides. It hangs at 140F normally with fans on and when the issue occurs with fans manually on low, it's very close to 150F. I believe in my case this could be my limiting factor. Other sensors seem to have more a percentage swing like the airflow and thunderbolt proximity sensors, particularly on the left side, which unsurprisingly is where my TB cable is plugged in from my dock. Website and Check for updates is pretty self-explanatory. The CPU only seems to swing from 150F to 160F before it kicks in. Show Macs Fan Control will take you to the program, if you have it hidden in the menu bar. Speed fan controller and temp monitoring for MacBook Pro Unibody (Nvidia) for Windows under BootCamp. Just guessing that the SMC is configured to throttle the processor at a certain temperature on a certain sensor and it manifests itself through kernel_task cpu usage. Current Macs properly manage temperature and fans. That's why I came to try MFC to force them to be more quiet, but slowing the fans leads to this kernel_task issue also. ![]() I'm not entirely sure why as load and temps seem pretty light. Automatic control wants to run the fans at full blast much of the time anyway. The processor needs fewer Watts of power to do the same tasks, so in theory there should be less thermal loss.FWIW, I have a 2019 MBP 15" w/ i9 and use it with two 4k monitors and run Docker desktop (therefore a background VM). My theory is, that is shouldn’t be normal. So my question is – what do you experience with the 2018 model, and maybe the previous few year’s models: is this normal? When the tasks stop, the fans quickly slow down. When the load remains 100% on at least one core for more than a few seconds, the machine quickly heats up and the fans kick in their 6000 rpm maximum, which is similar to a vacuum cleaner. Optionally, you can select Sensor-based value for both your fans and. Adjust the speed of the fans and press OK. Here’s how to do that: Open the Macs Fan Control and click the Custom button on the left side fan. When the machine is idle, the fans rotate at ~2500 rpm, but when I open a heavier web page (Facebook sometimes, a few minutes of, Pinterest), run an Xcode build, or basically do whatever, it quickly gets above 3000 rpm. If your CPU has a low heat approximately 45-50 degrees and the fans are at full speed, you may need to change that as well. Even the smallest task spins up the fans. The construction of the cMP concerning airflow is very well thought and efficient, and leaving the side panel off is not recommended and will effect negatively (mainly) the CPU compartment Temps. (I’ve got Xcode build times around 1-2 minutes.) The Mac Pro 4,1 and 5,1 default fan settings (like most Macs) are aiming for very silent operation but can result in (too) high Temps. ![]() On normal daily routine, it did not get noisy not even once. I experienced such loads only when I built large source codes (like Virtualbox source, took 1-2 hours) or exporting videos (10 mins-2 hours). If you want to investigate on Intel/ACPI machines, extracting one of the SSDTs should essential reveal the fan response curve, but its not meant to be configurable. When it got heavy load, after 2-5 minutes the fans used to spin up with moderately high noise and cooled down the machine until the load stopped. Its controlled by the SMC, now in the T1/T2 chips. I never worried about the temperatures or fan speeds. My old machine was almost complete silent during it’s 5 year life-span. I have exactly the same system on both machines, I restored it from Time Machine backup when I got the 2018 model. For work, I have an 1980x1080 and a 2560x1440 external display attached beside the internal Retina display. Here is how I use my computer: I am an iOS developer, and I use it to build and run iOS apps for work, and use it for hobby and media consumption in the evenings. I’m quite satisfied with the new computer, except for one thing: it is heavily using it’s fans and is very noisy. My previous machine was a 5 year old Late-2013 Retina MacBook Pro 15” with i7 2GHz. I’ve bought a 15” 2018 MBP with 2.6 GHz i7 and Radeon 560X last week.
