MacBook 13" 2019 - Regularly Reaching 100 Degrees While Gaming With eGPU?
When gaming, the CPU temps quickly rises to 100 degrees, then throttles down. From my quick tests, I've seen idle clock speeds of roughly 3500MHz, which then throttle as low as 2700MHz (more commonly around 2900MHz).
A past solution would seem to be undervolting the CPU, which Intel have recently disabled on all their CPUs, from 6th gen to current.
In other's experience, is it normal for the MacBook's CPU to reach 100 degrees so often? I've searched this on Google and my results lead me to believe these temps are quite high. Also, is there a way to reduce throttling, without making physical changes to my room or laptop?
Many thanks in advance.
MacBooks are very conservative with their cooling. Reaching 100° certainly isn't good for the hardware. I already feel uncomfortable when my CPU temperatures go up to 80. There are two things you can do here.
1. Install Macs Fan Control and make a more aggressive fan profile.
2. Go into windows power settings and customize the profile. By limiting the maximum processor state to 99% you disable turboboosting, which greatly improves thermals. You might experience performance loss depending on the games you are playing but it's probably worth it.
SOLVED. To anyone else who might have this issue, regardless of undervolting being disabled, Throttlestop can still be used to disable Turbo Boost clock speeds. Upon doing this, my CPU is now within safe temperatures of around 75 degrees. Surprisingly, while my CPU is now running at the lower base clock of 2.4GHz, performance actually seems identical with less hiccups/freezes. I would assume this is due to the CPU no longer constantly throttling performance. Problem solved! Now, let's just hope that months of gaming with high temps hasn't done too much damage...
Glad you found a temporary work around. It sounds like Apple should replace your cooling fans though.
Ah, interesting the high temps were only happening in Windows.
