Nitro 5 fans behaving erratically

Hello everyone,

I wanted to try asking here before I definitely sell this piece of **** laptop on the cheap. I got a Nitro 5 with the i5 8300H processor and GTX1050TI graphics, it had been working well for six months until recently when I cleaned the fans. Since then it has become absolutely unbearable, it raises fan speeds just because even at very low processor loads and temperatures. It never shuts the **** things off and it increases the speed to 3.5/4k RPM at random even if I just have Firefox with some 10 tabs and a couple of Word docs open. Only time it works as it should is when I'm on battery, but as soon as soon as I plug it in, it increases the fan speeds just because. As of me writing this post, this stupid POS is at 20% load, it spiked magically to 73 degrees after being stable at 47 degrees on battery and the fans are spinning at 4.7k RPM, both of them even if no app is using the GPU. Everytime I check and uncheck the CoolBoost option it quiets down the fans for a second just to increase the speed AGAIN.

This is absolutely unacceptable, the **** laptop is barely six months old and it's already behaving erratically. It never gets to shut down because it's not actually overheating, it just stupidly thinks it is overheating. Never buying a crappy Acer product again, but at least I want to try and fix this POS before I unload it on someone else. Customer service is not an option because the local customer service office said they'd take ONE MONTH to give me a reply, yeah, awesome, what I'm I supposed to do without a laptop for 1 month, tell my boss I quit?

Any help is GREATLY appreciated, please, I've tried everything, even tried replacing the thermal pasting and NOTHING has worked.

So everything was working fine until you went in there to clean the fans then it started behaving badly correct? Personally I never take off the back cover unless I absolutely have to, there are too many things that can be accidentally damaged like the temperature sensor, were you wearing a grounding strap? I clean the fans with a mini high powered vacuum used through the vents but too late for that now. It’s a shame because the damage was probably caused when you cleaned the fans so the problem won’t be covered by the Warranty.

On a practical note, go to Settings/Power and Sleep/Advanced Power Settings/Change Plan Settings/Change Advanced Power Settings expand System Cooling Policy (see snip below) and reduce the settings when plugged in, you could also reduce the CPU power when plugged in (The box in red). Don forget to change them back to High Performance if you game

Have you checked if version 1.28 of the bios fits the fan thermal table?

Exactly what I needed, thank you very much! I'm not sure if I have updated the BIOS or not, nor do I know how to do it. Is it done through Windows Update or through an Acer app?
