Nitro Sense displaying zero fan speed under auto/custom setting on AN515-42

Hey all,
This problem just popped up out of knowwhere. Only way to adjust fan speed is to click on maximum button. I click on auto or custom and it goes right back to zero. I guess it might make sense for the fans to not spin under auto option if the cpu is running cool, but not where I had it set for custom. Restarting Nitro sense helps, but only for a few minutes.

Let know if anyone has had this problem. Saw another thread where poster reported Predator sense exhibiting similiar behavior, but no resolution occurred. In the meantime will reinstall NS and cross fingers.

    Are you using a third party application to control or access the fans?
    Did you try updating/reinstalling Nitro Sense?
    have you checked by using application or playing games that needs more power from CPU?
    The fan is controlled by a thermal sensor. When the upper edge is reached, the fan starts. It is stopped when the lower threshold is reached by the cooling action.
    You can try reinstalling the Nitro Sense : Download and quick access application : Download

    Appreciate the response. Re-installed it. No change.

    So even if I used the 'custom' feature, disengage the auto button underneath, the fans will only start spinning if CPU/GPU is above a certain temperature? When I first purchased the laptop, I swear using the 'custom' feature allowed me to turn the fans on at will, with whatever speed I am using.

    I am concerned because would like to be sure I don't have a bad temp sensor. I hate going through RMAs... :s

    I am having the exact same issue I just got my Acer Nitro 5 AN515-52 on oct 12 and experiencing this issue along with freezing that is only remedied by closing and reopening my laptop

    @Red-Sun! What is the version of your bios? There is a version that fixes the system management unit! This chip controls the power saving function! However, I'm not sure if it will fix your issue: https://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_1.10_A_A.zip?acerid=636767338274193133&Step1=NOTEBOOK&Step2=NITRO&Step3=NITRO AN515-42&OS=ALL&LC=pt&BC=ACER&SC=PA_3#_ga=2.93151962.696199812.1540933681-443835305.1540933681
