Pros: -Compact
-Hidden in the case
-Customizable fan profile
-6 Channels /30W
-Reasonably priced

Cons: -One of the 6 channels is dead on arrival.
-The software is RAM hungry.

Other Thoughts: If all 6 channels was working i would give this product 5 stars

Pros: - 6 fan ports - allows for a separate fan curve profile for each port.
- Ability to control a watercooling pump
- Setting for silent 0% fan speeds
- Compact size
- RPM control based on either CPU or GPU temps

Cons: - Very glitchy and resource intensive software
- Slow support / development
- Fan compatibility problems
- Issues with 0% fan speed settings
- Requires 4 pin molex for power

Other Thoughts: At first this fan controller was great. I could set a different fan profile for each port on it - and tie it to my CPU and GPU temps. They have a feedback forum where people can report and vote for features and bugs which is somewhat active. After using it for a while and upgrading my system that's when things went downhill.

Software updates at first were fairly often but have since slowed way down. Some of the newer updates have caused issues that an uninstall/reinstall won't fix - they require regedits. There are people still reporting Win 10 compatibility problems or glitches with no solution. The software itself (even on Win 8.1) is laggy, resource (RAM+CPU) intensive at times, and crashes fairly regularly. It will randomly say the device is no longer detected especially after allowing the computer to sleep which requires a complete cold boot of the system. If the software crashes you lose the ability for it to ramp up RPM based on temperature which could be dangerous if something overheated. You're better off chancing the glitches you often find with Mobo MFR software - as then you won't be out $40!

PWM fans as well as some 3 pin fans connected to it don't work correctly below 50% speed. You'll hear them randomly jumping up to 100% and then going back down - which can be loud and annoying. Also there is an issue setting the fans to 0%. When a fan is powered up it is given 100% for a few seconds - presumably to accommodate startup voltages. This is fine for turning the computer on, but a major issue if you're trying to actually use the 0% fan curve option. There is no hysteresis control so it causes fan speed oscillation. Once your computer hits the set "on" temperature the fans will roar to life and they will settle at the % set which will bring the temp down enough to cause them to hit 0% again. Once the temp rises again you'll hear them roar up again - and the cycle continues perpetually. This could be avoided with hysteresis OR the option to choose startup voltage - many fans will start up at 7v (50%) without issue.

Another major issue is that there also appears to be a compatibility issues with some fans - especially Noctua PWMs - where the fans will randomly shoot to 100% if set below 50% speed. I am using Rosewill Hyperborea and they exhibit the same issue said here. Recently there have been complaints of this behavior being seen on 3pin fans as well.

The controller requires a 4-pin Molex for power - what year is this?? A SATA power cord OR adapter should be included - I have to install an entire modular PSU cable or spend $5 on an adapter just to power this thing because it's the only thing in my system with a 4-pin.

This brings me to the feedback forum - where both of these issues have been presented among others. The 2nd issue (PWM fans) appears to be a hardware design flaw that is not correctable without a re-design / replacement of the controller hardware. Those of us with the issue are told "sorry" and to not set fans below 50% - which greatly diminishes the value of the unit. The hysteresis suggestion has also received response from NZXT staff and is "under review" but it has been months since there has been any additional feedback.

At this point I would strongly consider waiting for a more mature product that has these issues sorted out.

Pros: - Very discrete
- A good amount of fan header ports (6)
- Easy to install
- Cam software easily links up with this and the Hue + system

Cons: I'm not sure if it just my controller that is bad or the software, but it only registers 4 fans are connected even when I have all the ports occupied. I tried 3 separate ports with a Be Quite! SILENT WINGS 2 120mm pwm and a Corsair SP120 pwm fan, both did not register on the Cam software. Will only register fans 1,2,5,6
The software is also still finicky and editing fan profiles can take a lot longer than it should. Sometimes the fans do not stay on the selected profiles or editing manual fan curves takes a little more finessing.

Pros: Small Design, Fits easily on the back side of the Motherboard mounting plate in my CM MasterCase Pro 5.

Very Strong Velcro, Will not be falling off anytime...ever.

Comes with a couple Y Cables so you can hook up 8 Fans with this one device *2 Fans on 1 channel will operate at the same speed* Alternatively you can use the Y Cable as a simple extension for your Fan cord.

You Don't need to be a genius to install it.

Direct connects to your Motherboard via USB connector with a black cable that is pretty easy to hide in a black case.

Works very well with CAM software. (Will function without it but all fans will be at 40% until you install the software). Inside the CAM software you can set up your own custom Fan Speed curves based on CPU or GPU Temps. This way your computer can stay quiet while performing office work...as your CPU/GPU get hotter your fan speeds will increase.

The Software is fairly user friendly. Took me only a couple minutes to set up all of my fan profiles (I am running 7 fans)

Fan Connectors are nice and snug...

Cons: Fan connectors may be too snug for some....if you are not 100% Sure you are plugging the fan into the correct port you may find it difficult to unplug the fan.

Fan Connector Ports are not labeled on the device itself...really just a minor inconvenience more than a con though.

No Power Curve support for MB Temps

Molex is the only power Cord of option. a SATA power option would be nice for those that are trying to do away with all of the Molex connections on their modular power supply.

NOT ONCE has it offered to do the dishes....

Other Thoughts: I had an Old Zalman fan controller in my old CM690 case that I never liked the appearance of so I modded the mesh to allow for the case to look like it was built in. With this fan controller I don't need to cut extra holes in my case to mask the ugly fan controller. It Doesn't take up the 5 1/4 drive bay and stick out of the front of my case. Don't need to reach up to my case to manually control my fan speeds...

I have already recommended this product to my other Custom PC building friends...I have only had it for a couple weeks.

Pros: Good idea

Cons: Sneaky software

Other Thoughts: What they don't mention is that their downloaded software ties your computer performance to their database somewhere in "the cloud". If they had made this a bit of standalone software, I would have kept this unit. Considering that I went to extreme effort to learn how to assemble my own new computer just to get away from the specter of Windows 10 installed on a prebuilt, I'm not about to give any data of any sort to yet another third rate third party marketeer. Just that "CAM" wanted me to create an account with whoever they are (looks like a separate site other than NZXT), got me really suspicious. How many ways can you spell telemarketer???????????????????????????????????????????????????????????????????

Pros: - 6 PWM capable connectors
- Very small profile. I have it on the backside of my mobo panel and the rear case panel has a good half inch of clearance.
- Very easy to set up. Plug in the USB header to the mobo and the micro-USB into the controller, then connect the molex connect to its respective power cable and then plug the barrel power end into the controller. Just install the CAM software and select the Grid+ in the installtion process.
- Allows custom fan curves on a per-fan basis (up to 6) and you can name each fan individually for ease of customization and control.

Cons: - It turns out there is either a hardware conflict or a software glitch that makes any Notcua PWM fans plugged into the controller to "breathe" or rev up and down slowly (creating a breathing like effect) and no change of options or custom fan curves can fix it.

A brief Google search shows a NZXT Forum post from 01/09/16 and a NZXT Staff member made apost stating they are working on the issue, so it's good to hear that they are at least investigating it. Hopefully it get resolved soon. Sure, it's not terribly annoying, but Noctua fans spin pretty dang fast and can get kinda loud.

Other Thoughts: The CAM software is a little unrefined as of this writing but from what I have seen of previous editions, it's headed in the right direction. I am thoroughly impressed by NZXT and how quickly they have established themselves in the custom built PC market as a very reputable brand that actually listens to their customers.

*UPDATE* 01/17/16 - NZXT got back to my bug report in two days with a very detailed explaination that I have provided below.

"So this is what I got from the hardware engineers. It sounds like you may need to keep the fan above 50% to avoid the voltage instability.
"Before anything, I am showing the correlation between duty and output voltage of Grid+&Grid+V2 as below :
0%(0V), 20%(4V), 25%(4.5V), 30%(5V), 35%(5.5V), 40%(6V), 45%(6.5V), 50%(7V), 55%(7.5V), 60%(8V), 65%(8.5V), 70%(9V), 75%(9.5V), 80%(10V),
85%(10.5V), 90%(11V), 95%(11.5V), 100%(12V).

Most of issues happened at 40~45%(6~6.5V) and starting voltage of most fans is 6~7V. So what we can confirmed the issue's duty(voltage) is close to their starting voltage.

In order to be compatible with most of fans(3-pin and PWM fans), Grid+&Grid+V2 is using voltage regulation like usual fan controllers because 3-pin fans don't have PWM IC and communication by PWM duty via 4th pin. There are two ways can access voltage regulation: Use variable electrical resistance serially into circuit or PWM method. We are using PWM method to adjust the output voltage that can have compact circuit design and no big heat dissipation problem. But PWM method has problem in providing stable voltage while the difference from 12V is too big.

After test with Noctua NF-F12 and NF-A14 PWM and other PWM fans, we did repeat the issues but not all of them had this issue. So we checked with suppliers of fan and PWM IC both and found some PWM IC inside PWM fans have protection against unstable input voltage. And Grid+&Grid+V2 using PWM method just did this under 50% duty so cause this issue of spin up and down. That's why most of issues are on PWM fans not 3-pin fans.

So it is the issue we can do nothing in software and firmware update. It does require us to make a big upgrade on hardware design. The issue can only be solved on next Grid+ (Grid+V3 or other names) which can provide both voltage control and PWM control for 3-pin and 4-pin fans separately and automatically.""

Kudos to NZXT getting back to me in a timely manner and for a thorough explanation. I will be sending my back and waiting for the Grid+ 3 or whatever they call it.

Pros: Tiny, easy to setup, works great!

Cons: The controller has a very bright white LED that you cannot change the color of nor turn off. I wouldn't mind it so much if either of those things was an option but it's annoying to have a single white LED in a computer that may be themed a different color.

Other Thoughts: This review marks the third one of these controllers that I've used. One in my personal PC and two in builds for clients.

I love how tiny this thing is and the fact that I can control 6 fans independently from my desktop with the Grid+ software. If you either don't have space for a 5.25 controller panel or don't want one, get this controller.

Pros: It's tiny, easy for managermen cable. The software gives you a full custom for controlling you fans base on a CPU or VGA temp nor % load and very easy to work with. It's can drive 10 fans of my systerm without problem.

Cons: It's not cheap.

Other Thoughts: Overall it's very good fan controler.
