![]() Have you cleaned the fan blades as well as the fin area of the heat sink so the heat is truly being pushed out?Īlso you might want to clean the old thermal paste and apply a fresh coat. Adding images to an existing questionĮven still this sounds like you need to do a bit more! Post a screen snapshot of the main window making sure you capture all of the sensors (may need to take a second snapshot fo the ones at the bottom). I would look at getting a better thermal monitoring and fan control app like TG Pro I find its the best out there! Install it and disable/remove MacFanControl so you don't interfere with TG Pro. Here the configuration of TG Pro Auto Boost: The fan(s) turn off by the hardware if the temperatures are low enough, and takes a long time to turn on when the temperature starts to rise, I have taken extreme measures and completely disabled the system, and assigning the work to Auto Boost: I rule out the idea that it is a MacOS problem since in the boot manager, I have left it for a few minutes and it turns off, I am only able to keep it on with the TG Pro application, with the Auto Boost option well configured (to the extreme). MacOS Catalina 10.15.7 The Apple Hadware diagnostic test has been passed: There was no problem found.ĭuring the recovery boot and diagnostic hardware test, the Mac becomes hot (57☌| 70☌| 85☌| 90☌), the Mac becomes stuck or shuts down, and the fan activates with a delay.Īfter reading answer, this is what I've done:ġ- Clean the fan blades (I had already checked them and they are not obstructed or dusty)Ģ- Apply thermal paste to the CPU only on the chip, a thin layer (the thermal paste does not completely convince me since it has a thermal conductivity of 0.7W/MK, it is of the Sabo brand and it is composed of silicone and metallic oxide)ĭespite all this, I cannot work with confidence since the moment the temperature exceeds the threshold of 70 -80 degrees Celsius for a fews seconds or one minute the Mac shuts down. MacBook Pro (13", 2017, Two puertos Thunderbolt 3) My Mac's fan controller is set to auto and/or 3000 / 4000 / full blast. Mac's Fan Controler is acceptable, but it does not work properly with the auto option however, it works well with custom rpm. If I set the user to auto login, it works with the MAC's Fan Control set to 4000RPM, because the Mac cools down and then works with Safari and other apps and tasks. Even when the Mac is hot (57☌| 70☌| 85☌| 90☌), it becomes stuck or shuts down, and the fan activates with a delay the fan then begins to run at a low speed and the fan continues to run at a low speed.
