Hey Guys,
I'm adding an external radiator to my setup and am not wanting to run the fans from the PC. Reason for this is it will be extra cabling I have to run from the system so I am looking at just powering the 4 fans from a wall outlet. I am thinking about buying something like this:

And then wiring the fans to it. Thoughts?

Thanks.

Josh

Need to watch the amps. ;)
Most of those little adapters only hold 1 or 2 amps. That equates to 1 adapter per fan. You need something better than that.
Think small automotive battery charger.

Could get a 12V power brick from a laptop or something similar and wire a fan splitter to it.

OK. Lets do a little comparison. A standard motherboard fan header can take 1 amp without burning up. How many of these fans would YOU run off that? Me personally, 1 high output fan per header. I trust no companys advertised fan specs.

Thanks for the info guys. Yes I realized that was a AC rectifier. I was going off what the specs said if .13amp per fan so was looking at 2 amps total output thinking that would be okay. Thanks for the help!

I am actually running 4x 0.25A fans on 1 header right now

Why not a cheap 300w fanless PSU? I don't think I'd even worry about quality, really, since it would only be powering fans?

Decided to just build a long cable to run from my system to the radiator. I'm making it with a bullet plug on the radiator side to allow quick disconnecting of the radiator if need be. I am then building a small breakout box to split the power into the 4 fans along with 2x white LED strips for accent lighting. :) I'll have pictures tonight for people once it's finished.
