Nitro 5 an515-54 fan rpm 5000+ even on idle

This looks like corrupt FW of the EC (embedded controller), you have to wait for BIOS/EC update or give it to a service center to reprogramm the EC. You have one more option - to mod your BIOS and then disable EC Fan control and adjust your own fan curve...

Update: just took this laptop from repair service, and there said it's a hardware issue, something like a short circuit in some component. This is my first acer laptop and i got this peace of ****. It's a last time i bough acer. batmalin said:

Go to ControlPanel's edit power plan. Click change advanced power settings. Click process power mgt folder in the box that pops. Click system cooling policy, Try setting both to passive when possible. Jack E/NJ

>>>yes, looks like>>>

What does 'looks like' mean? Was it or was it not stuck on high speed since when you first acquired the laptop? How long ago? Or are you unsure? Jack E/NJ

yes, the fan speed was high since i bought this notebook, but then I paid less attention to this problem because it was actively used most of the time, the laptop was bought less than a year ago, and yes, since then, to find out the reason why the fan speed never drops below 5000 rpm, I took it apart to clean it from possible dust, but I didn't find anything like that.

>>>Bios V1.32>>>

Have you checked for hidden BIOS menu fanspeed options by pressing Ctrl+S in the Advanced & Main tabs? Jack E/NJ

It seems that this is what I'm looking for, I did not find the configs for my model (in the pool requests too), could you tell me from which model i can find suitable configuration or documentation describing the required read/write registers? Thank you very much for the answer, I was looking for something like this for a very long time

ok, I figured it out, but the situation is similar to what it was, I can overclock the cooler to 100%, but when I set the values to 30%, the speed does not drop below 70% p.s. yes i disabled every NitroSense services

I checked hiden menu, but there is only rst/ahci switching options, is there should fancontrols options? it changes everything if so

You are welcome!

Yeah, OK. But don't waste any time. Arrange for warranty repair service pronto. Jack E/NJ

Update: just took this laptop from repair service, and there said it's a hardware issue, something like a short circuit in some component. This is my first acer laptop and i got this peace of ****. It's a last time i bough acer. batmalin said:
