Projectors are a valuable tool for presentations and home entertainment but they can encounter issues over time. A malfunction in the cooling fan caused by overheating and resulting in powering down at random times is a common problem. This guide will guide you step-by-step on how to safely and effectively replace the cooling fan of a projector.
Projector Model: Happrun H1
Note: The projector may be hot, so ensure it cools down before you start disassembling it to avoid burning yourself. Make sure the projector is fully turned off and not plugged in. Allow up to 20 minutes for the projector to cool down.

Hi Tulika, thank you for the guide!
Is there a chance you can provide me with the messurements of the fan and maybe you know the voltage and RPM's it runs on?
I want to replace it with a quitter one like from Noctua or so.
Thanks!
Any luck doing that? I'm looking for the same solution.
@rudyazoulay, I jsut took apart my projector and this guide is just something weird.
There are 2 turbine type fans
DC Brushless Fan, Model: DFM7530S, DC 12V - 0.25A.
Just put it into google and you will see that one specific. I didn't find the quite one yet.
Yes this is exactly the sort of fan I´m expecting to find in there!
Gonna be tough finding a pair that lowers the fan noise tho, undervolting them could result in inadequent cooling for the LED and LCD..
If you go on ebay or google, hit "75 75 30 radial fan" and make sure to check dimensions, voltage and current, you should definitely be able to find some compatible ones.
A little tolerance on current should be fine too, I would stay away from high RPM fans as they will likely increase fan noise.
The M in DFM7530S most likely stands for Medium speed
This guide is terrible, we see a picture of what is clearly a radial fan inside of the projector (Step 3) and at the beginning and end of this guide we see both a video and a picture of an axial fan (with completely the wrong dimensions for that matter).
I´ve gotten my hands on a similar projector and intend to change the fans in there real soon, I´m guessing the projector has 2 fans as the LED produces a ridiculous amount of heat.
I´ll do my best to document as much as I can and update this guide soon
