Acer Aspire V15 Nitro fan(s) stopped working randomly

Since I bought this laptop less than a year ago, either one or both fans keeps on randomly and completely switching off upon random reboot making the laptop overheating badly...

The problem may last several days (or even weeks) with absolutely no spin at all, and then magically after a system boots up working again for some time before the problem arises again.

This is a very strange issue, as it affects both fans (sometimes only one is affected), so I really doubt it could be a faulty fan issue. I'm thinking more of a capricious controller or anything like that.

I tried a fan software monitoring tool that is able to control fan speed.

When the fan is operating normally, its speed can be controlled BUT when the fan decided to suddenly stop working, nothing can be done. Moreover, this issue happens no matter the OS (either Linux or windows).

Do you have ever eared of such a strange issue, or have an idea what could be the cause of this?

I'm disapointed, this has been more than 6 month and still no solution found!!!

I returned product to RMA already twice, and they never solved the issue, pretending the laptop was working as expected,

but the fact is that this issue is random and they are not seeing there is a real problem.

Second time they said they changed motherboard as I told them to do so, but at my great disapointment issue just happened again...

this makes my laptop almost unusable, I dont know what to do...

And I didn't see lots of complain except mine until now....

If your laptop is overheating during use, see the Acer Aspire 5253 Is Overheating problem page for possible causes and solutions.

After 6 months and 2 returns to RMA finally found the answer here:!!!!!

I was surprised no one had report this issue before, it was happening with external monitor connected to laptop..

As the link above indicates, you must unlug any external monitor connected to the laptop during boot, and plug again after boot... a very strange issue!!!!

Have exactly the same problem, also with an external monitor connected. It often occurs after waking up from energy saving mode. Seems like they still havent fixed it, I'll try your solution later.

I am only going to speculate on this issue because it doesn't really look like the fans are the culprit here. My suggestion is to check for any blocker, broken piece or materials that are interfering with them.
