Nitro ANV15-51 Nitrosense buggy, fan not spinning, no mode available, cannot control fan speed

CZE · June 8

Hi, I bought Nitro ANV15-51 during July last year. 1 week after buying, Nitrosense app was running into issue already: fan not spinning + app as good as useless since any clicking wasn't resulting in any function. I brought to my country's service centre, but same issue happened again few days later.

At that point, I figured that a temporary fix was to just re-install Nitrosense app even though we as consumers shouldn't have to be troubled into doing as that's not how the app should be functioning.

Anyways, I just re-installed it everytime it happened, until the most recent update to Nitrosense where I believe they tried to fix the issue. However, it only lasted a week for me before the issue happened again. Now re-installing Nitrosense doesn't work either, so not only did Acer NOT fix the issue, they also made the temporary fix broken.

I have tried re-installing Nitrosense, checking for any Windows update, running the cmd "lodctr /R", and basically any plausible method I could find online, but the app is still not working (I can hear the fan spinning but I cannot control it through app).

Please advise what do I do now, but I will NOT do a factory reset because as a consumer, I should not be troubled into doing that as a result of the company's failure in making a well-functioning software. I also tried using the previous Nitrosense version but it would just say "MUI_OPERATING_MODE_UNDEFINED".

TL;DR
Nitrosense not working: Laptop temperature and fan running speed not detected, no mode available, cannot control fan speed, re-installing or running "lodctr /R" no longer fix the issue.

Welcome @CZE,

Try Windows Performance Counter reset:

1) Close the NitroSense app;

2) Open a Command Prompt / Windows Terminal (Administrator mode);

3) Type these commands (copy & paste):

%SystemRoot%\System32\lodctr.exe /R
%SystemRoot%\SysWow64\lodctr.exe /R
winmgmt.exe /RESYNCPERF

4) Restart your computer.

I symmetrize with you as the Nitro Sense app has been problematic for a long time post my 2020 Nitro AN515-56 version, as on that model laptop Nitro Sense worked 100% for me at the beginning, but in some circumstances and later on with Win-11 updates and a clean install, the setup.exe didn't work for the app and I needed to install this app within its folder for it to install and be triggered from the keyboard NS key.

I don't know the solution for your NS problem but try and see if you can install NS within its folder .exe instead of from its setup.exe. as that is how I solved the installation problem for my Nitro AN515-56. Good luck.

Hi, how do I install it within it's folder? Isn't setup.exe within it's folder as well?

OMG, that worked for me, once restarted, the fan is detected and the modes are available and the fans respond to what I select.

Thanks for the help.

If your Nitrosense fan service isn't working, try reinstalling the software from the Acer website. Ensure you've disabled fast startup and consider a system restore or removing any potential antivirus conflicts. You may also need to update your BIOS, check for loose cable connections, and verify proper ventilation.

@eGomes I have the same problem here. I tried everything, reinstall multiple times but won't work. Now i tried your version with cmd comand. I tried 3 times, restart the computer and nothing. The app is still blocked. In the app I have a warning message that said something like: You need your computer to be 40% battery and on charge in order to switch modes. My laptop is on charge and at 80% now :). If you have a suggestion please. Thanks
