After listen to annoying fan noises for way too long I figured that I could dig into the framework EmbeddedController source code to see if it could be fixed. Well, I found that the temperature points for the fan can be adjusted! And that’s all I wanted. **WARNING** : running your laptop at higher temperatures might shorten its lifetime. This _might_ not be covered by warranty. Misconfiguring a “halt” temperature could result in a long recovery session. **Prerequisite** Get a ectool version with frame.work support (see e.g. the fw-ectool tool (link removed due to spam restrictions)) and build it with `make utils`. **Relevant commands** List the RPM target of all fans ```auto $ sudo ./build/bds/util/ectool pwmgetfanrpm all Fan 0 RPM: 1953 ``` List all temperature readings ```auto $ sudo ./build/bds/util/ectool temps all 0: 317 K 1: 323 K 2: 319 K 3: 309 K 4: 324 K ``` List the temperature thresholds ```auto $ sudo ./build/bds/util/ectool thermalget sensor warn high halt fan_off fan_max name 0 0 361 371 313 335 F75303_Local 1 0 361 371 313 342 F75303_CPU 2 0 360 370 313 335 F75303_DDR 3 0 323 333 313 323 Battery 4 368 376 378 377 378 PECI EC returned error result code 3 (all temps in degrees Kelvin) ``` Here is a temperature translation: ```auto sensor warn high halt fan_off fan_max name 0 0 88°C 98°C 40°C 62°C F75303_Local 1 0 88°C 98°C 40°C 69°C F75303_CPU 2 0 87°C 97°C 40°C 62°C F75303_DDR 3 0 50°C 60°C 40°C 50°C Battery 4 95°C 103°C 105°C 104°C 105°C PECI ``` **Setting new tipping points** Let’s set the CPU fan\_off point to 60°C (~333K) and the maximum speed to 80°C (~353K) via thermalset ```auto # thermalset sudo ./build/bds/util/ectool thermalset 1 0 361 371 333 353 ``` Set the Local and DDR points to 47°C-70°C (320-343K) ```auto sudo ./build/bds/util/ectool thermalset 0 0 361 371 320 343 sudo ./build/bds/util/ectool thermalset 2 0 360 370 320 343 ``` Verify that the new tables, temperatures and fan RPMs ```auto sudo ./build/bds/util/ectool thermalget ; sudo ./build/bds/util/ectool temps all ; sudo ./build/bds/util/ectool pwmgetfanrpm all sensor warn high halt fan_off fan_max name 0 0 361 371 320 343 F75303_Local 1 0 361 371 333 353 F75303_CPU 2 0 360 370 320 343 F75303_DDR 3 0 323 333 313 323 Battery 4 368 376 378 377 378 PECI 0: 317 K 1: 322 K 2: 319 K 3: 309 K 4: 325 K Fan 0 RPM: 0 ``` Enjoy a way more silent Laptop! ---

> [@NM64](#): > > Psst: > […] fw-fanctrl was the reason I looked into the code, it’s a great tool. But I was concerned about what might happen if userspace crashes / hibernates / … so I wanted to see if the embedded controller could handle it. The corresponding ec code would be this [function that translates low/high/current temperature into fan %](https://github.com/FrameworkComputer/EmbeddedController/blob/main/common/thermal.c#L39). I don’t think a linear function is great for this, so fw-fanctrl does have an advantage here, but the simplicity and stability of an ec managed fan were key for me. ---

@Rene_Treffer Thanks for the info! I was looking for a way to improve the fan noise. After you changed the setting, how was your fan now? Have you seen the noise was improved? > The corresponding ec code would be this [function that translates low/high/current temperature into fan %](https://github.com/FrameworkComputer/EmbeddedController/blob/main/common/thermal.c#L39). Maybe Framework is not using the `main` branch, and it is only used to synchronize the code from the upstream project. Maybe Framework uses the `hx20` (For Intel 11 gen main board?), and `hx30`(for Intel 12gen mainboard?) branches. But the function is the same on these branches too. ---

> [@D.H](#): > > automagic mode setting goals I created an [updated version](https://github.com/Centurio-Macro/fw-fanctrl.git) of TamtamHeros fw-fanctrl which enables automatic switching between two fan curves depending on if the laptop is charging or discharging. I created a pull request for this. Until its merged into the original fw-fanctrl version mabye try the updated version. The current charging status of the laptop is read from the following file: `/sys/class/hwmon/hwmon2/device/status` On my Framework Laptop running Pop OS 22.04 this works. I don’t know yet if this path works for all Framework Laptops on all Linux distributions. So any feedback is appreciated. ---

That is a valid path on EndeavourOS (arch derivative) as well. The same status variable/file is also at `/sys/class/power_supply/BAT1/status` I am not sure which path is more stable and least likely to change. Consider having a hard-coded default path for charging status read, that is also can be overridden by config file? ---

> [@D.H](#): > > Consider having a hard-coded default path for charging status read, that is also can be overridden by config file? Good idea, just committed that change. By default the charging status is now read from `/sys/class/power_supply/BAT1/status`. It can be overwritten by providing a path inside the config file. ---

I took a minute to look at your code. I am wondering, instead of separate system service, could the two separate fan speed maps be triggered by tlp’s sensing of “on AC” vs “on batt” instead? Might be more complexity than the overhead savings is worth, but I thought I would mention the idea. ---

> [@D.H](#): > > instead of separate system service I would have to take a look at how tlp works. Right now the service accesses the file once per second. The CPU time compared to the rest of the system should be almost unmeasurable. I guess the reason for the existence of the system service is primarily the convenient automatic load of the python script at start up. ---

@junaruga yeah, the machine is way more silent now. It still depends on workloads on how it behaves in detail. But normal browsing can be silent. It’s such a pity that undervolting is locked on the 11th gen even with unlocked BIOS. For the fan curve this is just a linear one. I would have preferred a non-linear one, e.g. the square of the value, like `100 * (cur - low) * (cur - low) / ((high - low) * (high - low))`. Or a mix with the current one. The downside is always that the machine will run hotter. Keep that in mind. ---
