Powering 12v fan from 240v Twin & Earth cable

[ADarkDividedGem]

Hi,

I am wanting to power a Noctua NF-S12A 12v fan from a Twin & Earth cable which I assume is 240v. For this to work I am also assuming I will need some form of transformer e.g. 240/12v 60w Electronic Transformer with terminal block that I will connect between the Twin & Earth cable and the 3-pin fan connector.

That's my simplistic view of the project but I just wanted to pass it by some people more knowledgeable than me and to get any advice on which transformer to choose as there are many to choose from.

Thanks

The fan requires 12V DC, so this: http://www.screwfix.com/p/halolite-led-constant-voltage-driver-1-16w/85503 would be suitable.

The one you have linked to is designed for halogen lighting, has an AC output and will have a minimum load far greater than the fan, so totally unsuitable.

Or you could just buy a 240v fan and save yourself a lot of work, time and complexity.

Any money you save could go towards a DMM to reduce the number of assumptions you make.

The main reason for this fan is it's low dB rating so unless you can find a 240v fan that can be as quiet as 7.4 dB(A) then I am happy to work on a more complex project.

I don't know what your requirements are for the fan, so I won't try and find one for you.

I only know that although it seems to be a computer cooling fan, you don't want to use it in a computer.

Nor is it a transformer despite what the manufacturer says.

Something like this would be more than adequate for your needs
