Can fan be replaced with quieter model?

This is a relatively low budget projector, and one of the main drawbacks is the pretty loud fan. Anybody opened one of these? I'm curious what size the fan is, and whether I could replace it with something quieter and potentially more performant, like one of those smaller Noctua fans (I believe they're part of the Industrial series).

I've only had it for a few months, and with just a few (200ish) hours of playtime, it's getting considerably louder. I could send it in service for a good scrubbing, this should be covered by the warranty, or I could convince them to do it, but they will return it with the same bad fan and I will have the same problem over and over again, so I'm thinking fan swap and filter.

Let me know if you've had a look inside or found some details over the web, thanks in advance!
