Powering Fans from a wall outlet...

[JLambeth87]

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.

Better yet, how about this?

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.

why not something like this?

Again, 2 amps or less. That's one of these per fan.

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

I cant really find much tech specs on the fans but it seems each one only draws 0.13A?

Op your first link is a transformer with no rectifier it will output 12v AC.
You want something like this I run a TEC off of this if you ebay search for 12v DC supply they are a dime a dozen.

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?

 

[JLambeth87]

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.

Josh, Though the quality is not that good here is an older picture of my MO RA3 420 Pro next to my CM HAF932 Adv
