Aqua Computer Quadro PWM Fan Controller with Ambient/Backlight Connector

Don't be fooled into thinking this can "only" control four case fans. There are four CHANNELS. Sure, you might connect just four case fans, but you also could connect a bank of four or five case fans on each of the four channels.The unit is quite small, but it allows you complete control over PWM fans, including the option of turning them off altogether, which is very rare. Nearly all fans which follow the Intel PWM specification will, by default, go to 100% output when the PWM signal is at zero. This is intended as it is a safety measure in case the signal really is lost. It would prevent overheating.This device gets around that. It has to be properly connected and functional in order to halt case fans altogether. If you, for example, pull a lead off of it, your case fans will run at 100% again.I have an Aquaero which controls this little device and for Aquaero owners this device acts as an extension to an Aquaero, adding four more PWM fan outputs. Ideal maybe for Aquaero 5 owners who only have one PWM channel, or for Aquaero 6 owners who want more than the four PWM channels their Aquaero comes with.

I haven nothing but good words for this little controller. I've tried the NZXT one and the Corsair Commander pro and this is orders of magnitude better. Not only is it smaller but it uses molex power so it can power a LOT of fans. I have 15x 120mm fans running from this as outputting pwm for two DDC pumps and an additional 92mm fan. Works perfectly with my temperature sensor too. Oh and the software.... it is on a whole other level. I honestly can't recommend this enough. Stellar product.

Awesome controller that has very flexible software, although that means it could be a little overwhelming to begin with.Warning: only works with PWM so make sure all your fans are 4 pin.

Bought this to pair with my Aquaero Pro 6. Problem is it doesn't come with an aquabus cable. Its difficult to find the correct cable that has the small connection. Also this fan controller doesn't seem to work correctly with 3 pin fans, it runs them constantly at 100%. The same fans work perfectly with the Aquaero.All in all I'm pretty disappointed. Its a tidy compact unit though.

Had my loop set to target a water temperature in no time.

I bought this controller so that I could base my case fan speeds on my GPU temp. My CPU is cooled with an external intake radiator. It hardly breaks a sweat when playing games whereas the GPU is pumping hot air all around the case. Works like a charm. You can also create user-defined virtual sensors. So now my case fans are linked to a combined temperature of both the GPU and the CPU. Honestly so much better than motherboard software or other fan controllers I have tried.Also includes and aRGB controller for the money too.

I bought this because I was fed up with the ASUS AI Suite crashing all the time, otherwise the extended fan controller that came with my Asus Motherboard would have been fine.I was rather annoyed that the Aquasuite software doesn't any kind of automatic setup (that I could find) and all the software temperature sensors on my system (mobo, memory, CPU, closed-loop CPU cooler, PSU, etc) all had to be manually hooked up to the Aquasuite software from a tree control. There is no wizard for these - you have to add them manually one at a time.I'm sure the software is great once it is set up but my initial impressions are that it is all too much hassle.

One of the best controllers out there, specially considering the price. Aqua Computer software is great.
