I MADE THIS OPEN SOURCE APP FOR INTEL MAC USERS USING WINDOWS

For a while I couldn't find a good free option to control fan speeds on my intel Mac on windows, so I wrote my own, and I'm sharing it in case it's useful to anyone in the same situation.

It's called RPMac. It talks to the Mac's SMC directly to read fan speeds and temperatures, and lets you set each fan to Automatic, Maximum, a fixed RPM, or a temperature curve (ramp the RPM between a min and max temperature on a sensor you pick). It also has an optional on-screen overlay for RPM/temps, light/dark themes, and a small command-line tool if you'd rather script it.

Honest limitations: I've only been able to verify it on a couple of Mac Pros, so I'd really appreciate reports from other models (whether it works or not both are useful). Macs with the T2 chip (2018–2020) aren't supported yet; the T2 changes how the SMC is reached and I'm still working on that.

Source and downloads are here: https://github.com/golirt1/RPMAC/tree/main

Not selling anything just hoping it helps someone and that the feedback makes it more reliable across different Macs. Happy to answer questions.

I Built a free, open-source fan control app for Intel Macs running Windows (experimental)

I got tired of paid fan control tools for macs on windows, so I built RPMac a free, open-source app to control fans on Intel Macs running Windows (Boot Camp). It talks directly to the Mac's SMC.

What it does

  • Real-time fan RPM + temperatures
  • Independent control for each fan the SMC reports (multi-fan Macs supported by design, but only tested on a single-fan machine so far)
  • Friendly sensor names (+ raw view of every SMC key)
  • Starts with Windows, minimizes to tray, remembers your settings (even after sleep)
  • Lightweight dark UI, nothing extra to install

I've only tested it on a Mac Pro (Late 2013, MacPro6,1). It should work on most Intel Macs up to 2017, but I can't test models I don't own. If you've got an Intel Mac on Boot Camp, drop a quick report model, how many fans it detected, and whether control + temps worked. Even "works fine on my iMac 2017" helps a lot.

Needs to run as admin (hardware access); it bundles InpOut32, a low-level I/O driver some antivirus flags as "potentially unwanted"
