Question: I like to use it on my laptop cooler with custom fans. Can i power this with an AC adapter?
Document: My builds are super clean now.CONS1) Only supports 3 pin fans, not PWM. Fine for me since I mostly use 3 pin fans.2) Requires power from the power supply. Could hook it up to the board, but seems like a lot of load on one fan header. Has an adapter in the box that allows you to use a standard Molex connection.
Great build quality, small enough to tuck away into a corner of the case, and affordably priced. I don't like having to use onboard 3-4 pin connectors for my case fans, and using Molex to 3-4 pin connectors creates a mess of cables. With the Grid, I was able to route all case fan cables behind the case, giving the case a neat &#34;cable-less&#34; look for improved air flow.
I needed this because my motherboard and power supply ran out of 3 pin fan connectors, this was just what I needed. I like the 3 white LEDs that light up when it's connected.
If you don't mind your fans running at 100% all the time this thing is great. I  stuck two of these  in my danger den torture rack to power my 12 radiator fans and so far all has been working well. Not a lot to say about it as it is so simple.
Really appreciate NZXT for making this awesome product. I now use it to connect all my 8 fans inside my Corsair Air 540 chassis; 3 intakes, 4 for push/push on my H105 radiator, and 1 for exhaust, all being connected to a single hub and are running 100%. Installation was extremely easy, and it even came with some extending cables in case you ran into an issue with the length of your fan cables. The unit itself is also aesthetically pleasing along with the white LEDs.
Wires 10 fans with one 3 Pin fan header, its simply amazing, now my rig runs cooler than ever.Comes with cable ties, velcro(plastic) and everything you need to get this thing installed.
Tiny box that is a great help managing the NINE fans that I have in my XEON 2620 chassis. Without it, endless loops of fan splitters
I was one fan header to short and this saved the day. I was able to reroute all my case fans cable to this which is located behind my mother board tray. Makes for a cleaner look.
You can plug this straight into the power supply, the motherboard's fan controller port, or a standalone fan controller. A must for a multiple-fan computer buid.
I can safely say that as long as NZXT is selling these, I will be using one of these on every build.
Answer: You can, but you would need a AC to DC power converter and a 3 pin fan connector to plug into the GRID.
