Apple’s shift towards its in-house chipsets means that machines like the M5 MacBook Pro will not have to deal with Intel processors overheating the moment you reach the home screen, but that does not mean the company does not continue to cut corners on cooling solutions. The latest example comes from benchmarking the M5, and when the new SoC is pushed a little hard, it can reach 99 degrees Celsius. Thankfully, it runs significantly cooler than the M4, concluding Apple has made those minor thermal adjustments while maintaining the same chassis.
M4 MacBook Pro effortlessly crosses the 100 degrees Celsius threshold, while the M5 MacBook Pro keeps it under that thermal ceiling despite both machines sporting the same cooler design
Both the 14-inch M5 MacBook Pro and 14-inch M4 MacBook Pro were pitted against one another in an in-depth video posted by YouTube channel Max Tech. While the M5 Pro and M5 Max models, which are reportedly arriving early next year will likely be equipped with a dual-fan cooling solution, Apple continues to incorporate its base versions with just a single fan and single heatpipe that helps to transfer heat, but looking at the results below, this solution is inefficient in keeping those temperatures down.
When running Cinebench 2024, Max Tech found that this cooling solution could not keep up with the M5, but it should also be noted that this test pretty much pushes chipsets to their limit, meaning that if there is not a robust heatsink screwed to the laptop, it will most likely thermal throttle. Fortunately, the positive outcome from this test is that the M5 runs much cooler than the M4 while drawing slightly more power, despite both machines having the exact same cooling solution.
Looking at this behavior, we can come up with two possibilities; either Apple has tweaked the fan to ramp up more aggressively in response to higher temperatures, or it has resorted to employing a superior thermal paste like the PTM7950, which, in several cases, outperforms liquid metal. You can take a look at the image below, along with the comparison details.
M4 temperatures when running Cinebench 2024 multi-core
- Core average – 100.9 degrees Celsius
- Core max – 114 degrees Celsius
- Core minimum – 94 degrees Celsius
- Package power – 18.4W
M5 temperatures when running Cinebench 2024 multi-core
- Core average – 98.95 degrees Celsius
- Core max – 99 degrees Celsius
- Core minimum – 99 degrees Celsius
- Package power – 21.81W
Considering that the M5 MacBook Pro obtained a massive framerate boost when running Cyberpunk 2077 with ray tracing enabled, it is impressive that a demanding game would probably have pushed those temperatures further since the CPU and GPU were working in unison. Still, the Apple Silicon kept pushing along.
Assuming you already own a 14-inch M4 MacBook Pro and do not wish to upgrade to the M5 MacBook Pro, whose base model is currently listed for $1,584 on Amazon for the Space Black finish, but want lower temperatures, you can invest in some PTM7950. The large thermal pad can be purchased for $35.99 and can be utilized multiple times for successive applications, but you should know how to disassemble and assemble a MacBook Pro before proceeding.
