Hello,

I tried using TPFanCtrl2 to reduce the noise from my Lenovo Z13 (6650 U model, running Win11), but could not get your software running on the system. Whenever I launch the program, I get the error message "failed to read FanSpeedByte from EC". failed to read

On a few other other issue threads, I saw that it was recommended to try a few of the previous versions, and found v0.62 of TPFanControl to be working - unfortunately, it only controls one of the two fans.

After downloading RWeverything, I checked the embedded controller during a low-load benchmark using a hard 9W limit and found 0x85 (if I understood the notation correctly, value 644F) to control at least one of the fans. During the benchmark, TPFanControl was not on the system, and both fans were running at a low speed. with rweverything 9wbenchmark

Here is also a screenshot of the EC with the fans off during idle. with rweverything idle

Can you please help me to get the software working? I'm happy to provide you with additional data to the best of my abilities. ^^

@Marvin-jlu @Shuzhengz

Exactly same issue on ThinkPad X13 Gen 3 and Gen 4. Same behavior, most recent version v2.1 will just give "failed to read FanSpeedByte from EC"

v0.62 Does work, but only for 1 fan.

Where you able to find solution? Any other software? Seems like X13 and Z13 are not working with [TPFanCtrl2]

@mrld341 Unfortunately, I could not find a solution. I tried every software that I could find, but none of them worked.
