I wonder how well this runs in terms of CPU, i have a Macbook Pro and i don't hear the fans very often. Except when i run Windows 10, the fans frequently blast

I wonder how well this runs in terms of CPU, i have a Macbook Pro and i don't hear the fans very often. Except when i run Windows 10, the fans frequently blast at the maximum level...

The only time I've ever heard the fans on my Mac Mini is when I run Windows Update. The strange thing is even though it is stressing the machine it's still slow at updating.

  Yeah I went for about a month thinking my Mac Mini fan was broken.

There's a reason for that, macOS loads a specific fan curve that prefers silence over performance, only kicking in a the last moment before the CPU overheats. This focus on silence also costs them in performance, but as long as the laptop is fast enough for most people, the raw performance probably doesn't matter to them. Windows doesn't about the thermal limits Apple put into place in their devices, so just treats it like a regular old laptop: boosting with fans turning whenever it needs to. However, it needs drivers to read the temperatures from the device and as far as I know, the Windows driver for reading those on Apple hardware aren't great (if they're available at all). This means Windows on a Mackintosh will always perform worse, because it doesn't have the same thermal information input as macOS has.

  This sounds completely made up. If you have more info than pure conjecture, please share. I would wager the sensor drivers for Windows were written by apple.

"If it chooses to, Apple could resolve or mitigate the issue with a firmware update that kicks in the fans sooner" Stuff like this is why I keep saying that Apple is a fashion company, not a tech company. Or more accurately, they're a company that makes technology fashionable. But apparently fan noise isn't fashionable, so they try to eliminate it, even if it comes at the cost of performance in what is supposed to be a performance-oriented configuration.

Windows has a power setting, that chooses between CPU throttling and fan speed increase.

You really can't judge Windows performance by how it runs on a Macbook Pro. Try it on a Surface or a Lenovo Thinkpad or Yoga and it will be a much better experience. They just don't have access to the Mac's proprietary hardware fan and power management controllers.

Bootcamp is intentionally gimped by Apple. If your Mac has an GPU and an integrated GPU, OSX can switch between them while in use to lower power or heat when no acceleration is needed. Windows, however, will only ever see the GPU, blasting it on full power decreasing battery life and making the computer hot. The windows drivers for the trackpad are really, really bad. The fan control in Windows seem off the charts. So don't judge windows based on running it on a Macbook, I guess. It's an abysmal experience, unfortunately.

  For the touchpad, only ever use this driver: https://github.com/imbushuo/mac-precision-touchpad https://github.com/imbushuo/mac-precision-touchpad (the Apple one is unacceptable trash...)

That's because bootcamp "conveniently" doesn't give Windows the same level of control that MacOS gets when it comes to running the fans. Nothing related to actual cpu utilization.

  Windows doesn't control fan speeds on native Windows systems either. At best, it's handled by vendor drivers. Often, it's handled by SMM interrupts.

    No, but on native systems you don't get Bootcamp Utilities installed, which makes the two setups rather different stories. A choice was made not to give Windows reduced capabilities, despite making sure that Windows gets augmented to work with your specific machine's hardware.
