This is a fork of https://github.com/cjbdev/TPFanControl. I've added a fix to allow TPFanControl to correctly control both fans FAN1 and FAN2 on Lenovo ThinkPad P53. This has only been tested on my P53 notebook. A working release build is included in releases area.
I use Visual Studio 2019 to build the project, earlier/later versions may work as well but are not tested.
As you probably know, Lenovo completely screwed up fan controlling code on Lenovo ThinkPad P53. There is a bug in either BIOS or Lenovo Windows drivers which results in a very long delay between a temperature event and the fan speedup or slowdown. Effectively, the fans follow a temperature that was actual a long time ago. Also on my machine fans do not turn off completely even after temperature goes below 50C. And I want my P53 notebook to be completely silent under no load. See this thread on Lenovo Community forum for details: https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/P53-CPU-power-management-and-cooling-bugs/td-p/4596511.
To avoid errors, either install tvicport manually or install the original version of TPFanControl found here, and run the dual-fan version instead of the original version.

Install TPFanControl from here: https://thinkwiki.de/TPFanControl. I'm using "latest common version, autostart by registry key as setup option, bug fixing, new options: startup in manual mode with manual fan speed adjustable, widget stays on top, optional slim widget. NEW: Hotkey integration." Here is a direct download link to the installer: http://thinkwiki.de/tpfancontrol/tpfc_v062.zip.

Copy TPFanControl.exe and TPFanControl.ini from this repository releases area over the installed files.

Stop "Lenovo Intelligent Thermal Solution" service and set to "Startup type: Disabled". At some point I noticed GPU fan is spinning like crazy despite max sensors temperature being below 50C as reported by TPFanControl. After I stopped "Lenovo Intelligent Thermal Solution" service, left fan's speed immediately went down. So "Lenovo Intelligent Thermal Solution" can interfere with TPFanControl.

I've also uninstalled "Lenovo Intelligent Thermal Solution" drivers. After you run Thermal Solution installer from Lenovo website, see where it unpacks temporary files and run this command from this folder: "dpinst.exe /U LITSDrv.inf" to uninstall Thermal Solution drivers. Not sure if this step is necessary.
The easiest way to run TPFanControl at startup is:
- Right-click on TPFanControl.exe and select copy
- Press Windows-r or search for run in the start menu
- Type
shell:startupin the run box - Right click in the window that opens and select paste shortcut
Note: this won’t start TPFanControl until you reboot.
