The oft stated вЂfactвЂ™ that CPU AвЂ™s heatsink gets warm air from CPU BвЂ™s fan is nonsense propounded by dabblers who fancy themselves engineers вЂ“ you will get the same differential with a cold Mac Pro as with a warm one, clearly disclosed in the above charts during the warming stage in the first few minutes of stress. The NB chip is the main вЂtraffic copвЂ™ which parcels computing labor out between the two CPUs and if you are wondering why CPU A always runs warmer than CPU B itвЂ™s that it also has additional traffic cop duties, so it works harder.

Components at idle rarely exceed 115F with only the hot running Northbridge chip (with an operating ceiling of 220F) running at some 125-140F. Now during normal, low stress use, this is no big deal. The charts above are neither in error nor do they represent statistical anomalies. I have repeated the above measurements dozens and dozens of times on any number and variety of CPUs and the results are always the same. What was Apple thinking of вЂ“ an increasingly common question when it comes to OS X? A cool electronic component is a happy electronic component. (Of course, thinking holistically, your Mac Pro gets warmer and you have to crank up the air conditioning вЂ¦.) The result is that everything runs hotter (bad) with the sole benefit being that the fans run slower and hence quieter. What Apple has done in Yosemite is to set the OS to ramp up the cooling fans far later in the heat cycle than in Mavericks with the result that CPUs (and other cooled devices) get much warmer before the fans speed up, with the minor benefit that less energy is used at idle. These charts display the temperatures of both CPUs (orange and red) as well as the power supply (green) and ambient temperatures (brown) and are logged over a 70 minute cycle during which a stress test utility loads up the CPUs to near 100%.ДЄs you can see, the temperature chart for Yosemite differs dramatically from that for Mavericks (and indeed for earlier versions of OS X, not shown here). Set forth below are two stress test charts from CPU upgrades I performed on 2009 Dual CPU Mac Pros: My findings are based on over a hundred data sets and are statistically significant. One of the strangest changes was made in the transition from OS X Mavericks to OS X Yosemite (10.9 to 10.10) and it relates to how the OS manages cooling fan speeds. I have expressed my frustration at AppleвЂ™s seemingly mindless and unending tinkering with OS X before.

Here are few screen shots to give you a better idea.AppleвЂ™s changes to fan management are a retrograde step.ДЇor an index of all my Mac Pro articles, click here. That makes the DrFan automatic mode the safest and the most correct one, the Apple should have had created. As for the DrFan automatic mode, it considers all thermal sensors together (not just CPU or just GPU) and preventively adjusts the fan speed, so that CPU and GPU temps never reach their default or user-defined threshold.

What DrFan does instead is PROPER automatic control with user-adjustable CPU and GPU temperature limits, as well as one-click manual mode via tray icon popup. Then EFI/SMC logic prefers to lower the CPU and GPU performance instead of kicking the fan in. first it waits for whopping 97-98В° C in silence. What inspired creating it: even with 2019 iMac models, Apple fan control logic in Boot Camp is still almost disastrous.

Now I feel it's time for the new thread dedicated to DrFan utility, which is a totally new fan control software for Apple iMac series (currently for 2012 to 2019 27' models running Windows via Boot Camp sans iMac Pro).

Hey All, 8 years ago I started a thread here at MacRumors forums about Trackpad++ driver (that thread is still alive, see ).
