Either undervolting the CPU or controlling the fans would be better than lowering wattage (both under Windows 10).ĥ0% CPU Speed on Windows 10 Hello,I have a MacBook Pro 8,2 (i7 2.2GHz) running without the battery. Please, if anyone has a way to get around this, other than using some tool to lower the wattage, let me know. I can't even control the fans under Windows 10 as that might mitigate the issue by making the fans run faster for a longer period. I've tried to find a solution and found that undervolting the CPU will probably fix it, but of course Apple locked the control over the CPU's voltage!Īpple, you have to push some kind of an update to fix this issue or at least allow us to undevolt the CPU to be able to use it at all, please! This is so annoying and makes me afraid to put any load on my machine. And even at 90C the fans are still running quite!

Under macOS, doing nothing, gives me CPU temps of around 40-45C but under Windows 10 in Bootcamp, sitting idle at 60-70C and at 16-20% CPU usage it goes up to 85-90C.

Hello everyone, so I have the MBP 2018 15-inch model.
