Helios 300 PH315-53-72E9. Fan replacement

I have a Acer Predator Helios 300 PH315-53-72E9.

I found out that my GPU fan rattles and takes a lot time to reach its max speed of 6122 RPM when I turn on turbo mode. The CPU fan works fine. As per the Acer's support and various other sources on the internet, I have to either clean and lubricate the fan or replace it completely. I have cleaned it but still the problem remains. The rattle just annoys me now as my friend have pointed it out to me.

As the service centre of my city is closed I would like to replace the fan myself to save time. So I have 2 questions:

Can anyone tell me the part number of the GPU fan?
My model have metal 4th Gen Aeroblade 3D fan.
Also can I upgrade it instead to the latest 5th Gen Aero-Blade? If it's possible.

Thankyou in advance.

Impervious here you have the part numbers you need to look for if you want to replace the fan(s) also you need to replace the fans with the compatible ones for your own model as the latest are most probably not even compatible so i wouldnt risk buying any and lubricating the fan only solve it in a few cases most cases the bearings are damaged or the internal fan components are a bit bent in any way that would require replacement and my advice always replace it no matter what its the safest to do to make sure it will work properly

I took it authorised service centre ad got the GPU fan replaced. No more annoying rattling noise! I forgot that I had three years extended warranty. Also, I had them reapply thermal paste. Now the beast is a lot cooler.

I do have one question. The CPU fan's black tape attached to the heat pipe/sink had loosened out because the technician didn't handle it properly while reapplying the thermal paste and decided not to reapply the tape back because it wouldn't stick. And I was informed that it didn't mattered much.

Is this okay? The tape must have some significant importance. The new GPU fan also came with it.

I am posting here for a second opinion.

Impervious if you mean the tape that seals the exit airflow vent yes that tape is very important its to isolate the hot air from coming out inside the laptop before exiting to the vents if its loose/damaged the airflow its not working properly its coming out inside of the laptop instead of outside as supposed to and will cause more heating inside as its not exiting properly if this is the case and if he said it doesnt matter then he doesnt know what he is talking about i would go back and make him reapply proper tape if they dont have it then make them replace the fan for a new one good luck

PS: any other loose tape than the sealing vent tape its probably fine as long as it doesnt affect any components around it
