Acer H6510BD: fan fail

I am getting "fan fail" around 15 minutes after booting my projector up. I can hear the fan still running before this error occurs. The lamp hasn't even expired yet, so it's not too old.

Any tips on what I should look at or documentation on disassembling this to inspect fans, to see if I can resolved the error?

I did find this to get it disassembled:

But the video isn't about fans; I'm not sure how many fans this has, I only see 1 so far.

[EDIT] Didn't see a lot of dust, but air dusted it out anyway while it was open. Same error returned.

From my understanding (not my personal experience), the fans in projectors can fail if the regulator that controls the fan's speed is not working properly. Projectors typically use very standard computer fans. So, even though the fan is spinning, it may not be operating at the proper speed, or it may not be reporting that it is operating properly.

You would need to open things up and replace the fan with a like make/model and then get it all back together properly.

There are more and more videos on YouTube about taking projectors apart and getting them back together, but that's entirely on you.

Of course, Acer will be happy to charge you well more than the projector is worth to do the same thing if you want them to.

Sucks when this BS happens to a piece of electronics you haven't owned that long. I feel your pain.

Yep, found one and got it disassembled thanks!

I'm not sure where to go from here. Namely how many fans this has and how to test which is failing.

I know there's the front fan, but I'm not sure if there's more fans such as a back blower fan. I don't see any videos on the matter.
