My time with the NZXT Grid 10 Port Fan Hub walked a fine line between doing what I am told along with trying to take things to the edge without breaking them. By this I mean I took a bunch of 0.18 amp fans, which works out to 2.4 watts of draw per fan and connected them to the grid and powered things with the Molex adapter. I was able to power the ten fan ports with no issues at this point. Where I did run into some power issues was when using high draw fans with others, essentially over drawing the power abilities, or when I had it hooked to a weak fan controller. I did all of my testing with the case split apart, so I could feel for heat before I melted the box, and while it survived, you could definitely feel the connections warming as I drew too much power.
The high current fans when used with the normal group would spin a bit slow, and almost immediately the connection warmed, so I shut down the testing by quickly removing said fan. On the aspect of the fan controller, you have to remember it is delivering the power to the Grid. So, if there is only 10 watts per channel on the controller, you will only deliver 10 watts to the Grid as well; something to think about.
Using the Grid as directed will deliver you both ease of the connectivity to up to ten fans, as long as you don't exceed 30 watts of power draw, and should deliver a very useful addition to your build. As it sits, many cases with fan controllers built-in don't cover this amount of fans, or the power amount. You could go with a fan controller, but it will cost you more money, take up a bay in the chassis, and not be as hidden. With the Grid, NZXT really hit the head on the nail in my opinion. Coming from a guy who has done many loops, and had case builds like the 800D where just filling the fan holes takes you to an amount of fans that usually requires a mess of wires and adapters to get it all in and powered, leaving a real mess to deal with. The Grid takes all of these ideas and cleans things up not only in the device offered, but in its ability to be placed anywhere and either shown off with its streaks of white LED lighting, or hidden behind things to keep the ten fan leads out of site from glances through the window.
The second best part about the Grid 10 Port Fan Hub, following its functionality first, is the amazing MSRP that NZXT has set. Looking at this from all perspectives; fan adapters, y-splitters, even Molex adapters all cost money, and when multiplied by ten, the cost gets pretty pricey as $2 per adapter. If you were to go look at a fan controller, average ones will cost you $20, and some of the better controllers go up to and even above the $50 mark. Now think back to the fact I can hide the Grid, I have options to power this system, and I have a one stop location for up to ten fans anywhere I see fit to attach it. Now let's add in the fact that the cost of the Grid is only a mere $11.99, and you can really appreciate what NZXT is offering, and I for one and glad I didn't melt mine, as it will be going into my next water cooled build for sure.
