The original fan suddenly started making an unbelievable noise that wouldn't stop even after cleaning, so I had to replace it with this one. So far, everything looks very good. The installation is easy, anyone with basic knowledge and almost no experience can do it (there are also several videos on YouTube). Just be careful when removing the old one, because right underneath it, the cable connected to the power button is stuck and if you don't pay attention, you will struggle a bit later to fix it... Also, in order to install it, you will need to remove the entire cooling system, so it would be good to have some new thermal paste to apply on the processor and wherever else it is needed.
