RPMac v1.5.0

The other app capable of controlling fans on Intel Macs in Windows — for free.

A full redesign of the interface, and the curve editor RPMac always should have had.

What's new in 1.5.0

• Graphical curve editor. The temperature curve is now a real chart you edit by dragging its points, instead of four sliders you had to imagine the result of. A live dot rides the curve showing exactly where the fan is running right now, and the axes label themselves in °C or °F.
• 5-minute history graph. A live chart of the hottest sensor and the fan speed, so you can actually see what your Mac is doing over time.
• Redesigned interface. RPMac now has its own window chrome with a live temperature readout, an icon sidebar (Fans · Sensors · Presets · Settings) instead of one endless scrolling page, and a proper app icon. Sensors are grouped by CPU / GPU / system with their raw SMC keys, and values turn amber and then red as they get hot.
• Fan names from the SMC. If your Mac reports a name for a fan (e.g. EXHAUST, MAIN), RPMac shows it, along with the fan's RPM range and a marker for the target speed on the speed bar.
• Live temperatures stay visible next to the fan controls while you tune them.

Download

Download RPMac-v1.5.0-windows.zip below, unzip it, and run RPMac.exe as administrator.
Keep RPMac.exe, RPMac.exe.config, smccore.exe and inpout32.dll together in the same folder.

If Windows blocks it: RPMac isn't code-signed, so Windows doesn't recognise it yet. On SmartScreen choose More info → Run anyway; if Smart App Control blocks it the app just won't start, so either turn Smart App Control off in Windows Security → App & browser control, or build RPMac yourself from source. This is normal for any unsigned utility that talks to hardware — the full source is in this repo.
