MacBook Pro 16 overheating problems with i9 CPU
We have received several complaints about excessive CPU temperature from users of the 16 ″ Macbook pro with an Intel I9 processor.
What is thermal throttling?
Electronic components such as processors emit heat that sometimes becomes difficult to manage by the dissipation system, especially on laptops which use a dissipation system with copper heat pipes and fans. You can contact ifixscreens for MacBook pro screen replacement. I have talked in the past in an article about how a heatsink and Heatpipes work, making a premise that you can read here.
When the dissipation system can no longer dispose of the heat, thermal throttling comes into play; this hardware technology inside the processor decreases performance to prevent the CPU from reaching temperatures that could damage it.
Software Solution 1: Disable Turbo Boost
Enable or disable Turbo Boost
You can manually enable and disable Turbo Boost using the Turbo Boost Switcher application. Turbo Switcher is available as both a free and paid application, but this tutorial uses the free version.
After installing Turbo Boost Switcher, launch the application. MacBook battery replacement by ifixscreens in United States. Click the Turbo Boost icon automatically added to your Mac’s menu bar.
By clicking on Disable Turbo Boot, this application will prevent the CPU during long processes with the workload by elevating how the rendering overclocks, reducing the temperature by a little, but at least the processor will tend to go less in thermal throttling.
Solution 2 Hardware: Replacing thermal paste and adding thermal pads
The second solution involves a hardware-type intervention, so it becomes a little more complicated if you are not familiar with the hardware of MacBooks and laptops in general.
We have adopted this solution with one of our customers who use the MacBook with i9 CPU to render, especially outside the home.
First, we disassembled the MacBook pro 16 “to replace the thermal paste with a Carbon Based High Performance with a higher dissipation coefficient. The value reported by the manufacturer was Thermal Conductivity: 13.4W / mK.
To remove the MacBook pro 16 heatsink, we have to completely disassemble the logic board as the screws are on the opposite side of the board; below is a photo of the screws that anchor the heatsink.
Disassembling the heatsink, we cleaned both the BGA (CPU and GPU) and the heatsink to remove the old thermal paste. Then we placed the thermal paste on both chips and fixed the heatsink on the opposite side.
Reassembling the heatsink, we placed thermal pads on the heat pipe to increase the dissipation on the aluminium chassis. Frankly, we noticed an increase in temperatures on the rear body and an evident decrease in the sensors of the CPU and video card; below is a photo of how we positioned the thermal pads that I link below.
The thermal pads used have a thickness of 1.5mm and are readily available online below the links.
With this “change”, the problems of overheating the MacBook 16 with intel i9 have decreased drastically, but we find that the button case heats up enough.
After the change, we did not encounter Thermal Throttling problems on MacBook pro 16 ″.
Other users have also changed this, experiencing up to 20 degrees less under stress.
