Basically, third-party hard drives don’t have a temperature sensor on them, so there’s no way for your MacBook to regulate the fan speed.

Many MacBooks have a temperature sensor on their hard drives or SSDs, and if you replace your SSD or HDD with a third-party model, you might encounter this issue. After doing that, start your MacBook again.Īfter performing the SMC reset, the issue should be resolved.Hold all four keys pressed for about 7 seconds, and then release them.Without releasing the keys, press and hold the Power button as well. Keep the keys pressed for about 7 seconds.Press and hold left Control, left Option (Alt), and right Shift.To fix this issue, it’s recommended that you reset the SMC.

Reset the SMCĪpparently, this issue appears on models with T2 chip if you turn on your device as soon as you connect the charging cord. What to do if the MacBook fan is stuck on high speed? 1. This can be a problem, but there’s a way to fix it. NOTE: Left side override done, now we expect increased left fan speed (Macs Fan Control show actual overridden fan speed), you can change it back with Macs Fan Control interface.ġ3.Keeping your MacBook cool is important, but there are users who reported that their MacBook fan is stuck on high speed. Change value for selection to "6000" or any other value (right click on selection, "Change Record" - "Value" menu item click, change value to "6000", "OK" button click) Select all addresses on Address List (bottom panel)ġ1. Select all found addresses (left panel) and copy items to the Address List (the red arrow button click)ġ0. Scan for "4444" (Enter "4444" to "Value:" field, "First Scan" button click)ĩ. Attach to MacsFanControl.exe process (top left button, select MacsFanControl.exe, click "Attach debugger to process" button)Ĩ. NOTE: You can choose ANY value, we need it only for filtering in Cheat Engineħ. Set constant value for Left Side - 4444ĥ. I found the way to override speed limitation by using Macs Fan Control and Cheat EngineĤ.

(CPU limitations may be unnecessary, but in my case the GPU Clock MUST be tuned down since the temperature will always go beyond 80 when set to default 1004 MHz)

These are the methods I'm using now: Max fan speed(smcFanControl) + Turbo disabled and CPU power limited to 25W(QuickCPU) + GPU Clock set to 640 MHz(MSI Afterburner) + 2020 Jan driver Hopefully Apple will eventually fix this. This fix is a little bit annoying, because you have to login to macOS every time before using Windows. Sadly preventing temperature from going above 80 may the only but temporally fix.

The recent macOS's update may have messed up something causing this odd behavior. Like many others, my Mac's GPU core clock will drop down to around 300 MHz minutes after the temperature gets 80+ degree, and with fluctuate between 300-500ish MHz even if the temperature goes down to around 74 degrees. People with throttle issues should definitely try this one.

The fan's speed goes from 5000 to 7000, and my MacBook Pro 2018 15-inch's temperature is now constantly below 72 degrees. Thank you so much! This method is by far the only method that actually works.
