Has anyone done a fan transplant recently to get a better/quieter Amiga 3000 PSU fan?

I'd like to try something like this.

Just open it up and replace the fan with one of the same size. I haven't done in with a A3000, but I have done it in a A4000T and several PPC Mac towers. Always worked like a charm.

It's a 2 wire fan. IIRC, the fan wires are soldered in place on the board. you could cut the original off and just crimp on the new one (standard case fan size btw) or just re-solder in the new wires. Either way, it's a very quick and easy job. You might even luck out and have an actual plug inside. The hard part is to find a case fan that is quiet enough for you! some of the cheap ones push a lot of air, but they are noisy as all heck.

Either way, it is always a good idea to open the power supply case and blow it out with Compressed air and then you can inspect those caps. If you are go at soldering, I would sugest re-capping it at the same time. That way you have a power supply that should be good for years to come. I would think that it is not an easy task these day to find a whole replacement PS.

That fan is the only thing that is moving air out of the 3000D so do not pick a fan that move to smal amout of air.

You can always pick a fan that you can adjust the RPM on so you can crank it up if you notice that your por 3000 is geting hot :)

Another good measure is placing a slot cover fan in one available slot to force more air shifting and then the PSU fan can be a quieter model.

Any reccomendations on a good, quiet 2-wire fan online?

You can buy a 3 wire model, 2 of the wires are for the polareties and the third is for RPM signal so just cut that sucker out of there :-)

Any update to this? I want to replace my fan in my A3K too.

I replaced mine by a "Fractal Design 80mm", my computer is almost quiet as my A1200 :thumbsup:

I've replaced my 4000D fan with one from Noctua, it's near silent while still pushing good amounts of air.

I've used the Nox Acid Blaster 80mm (http://www.nox-xtreme.com/en/cooling/acid-blaster-80mm) in my A4000 and A2000. It's a cheap (around 7 Euro) and quiet three-wire fan. You only need to use two of the wires. Another one will end up in my A3000.

I've attached a few pics of the replacement process...

I did so with 3000 - it became quiet at least twice.
