Amiga 4000 PSU Fan Mod
 

As you all know the original A4000D PSU fan is pretty noisy, so I'd like to upgrade it to something quieter, but also hopefully better. I found a few old threads but nothing recent, so just thought I'd ask if people still think this is the best replacement:

If not, any others I should look at? Also when I come to fit it, what precautions do I need to take when opening up and working on the PSU? I'm reasonably competent at soldering and working with motherboards etc but I am always cautious of anything that says 'Do Not Open' on it :)

Thanks.

looks good to me edd.

you just need to check if its a 2 or 3 wire fan.

precautions,only the obvios really.just make sure the psu is not plugged in.

I used very same in my plastic 128D. Does the job well.

recently modded my psu, cut couple of the fins away and installed another fan as well so its go 2 now

I fitted the new fan today, and wow what a difference! It is almost silent compared to the hoover-like noise it was making before. A must-have upgrade if you haven't done it! Here's a quick photo. I opted for soldering the wires together rather than trying to unsolder the old fan from the board.

looks good.

Make sure it is blowing in the correct direction.

looks ok from here,its pushing the air towards the rear(mains socket end):)

Replacing the fan is nice :)
This seems like a nice fan who's quiet and has also some nice CFM \o/

I also cut the metal backplate where the holes for airflow exist for even better airflow and hasn't failied me ever since :)
