AquacomputerOCTO Fan Controller for PWM Fans

Can't comment yet about the quality of the product because my board fried itself on first install. I requested an RMA from Aquacomputer and got an email back within hours with technical details and pictures on how to diagnose the board. They are sending a replacement board for a small fee as the over-voltage damage isn't covered under warranty. Despite the cost of replacement and inconvenience of having to wait for a new board, I am really happy about the level of service I received. Their website is a little difficult to navigate because it's mostly in German but the rep communicated directly with me in English and was surprisingly knowledgeable about the technical details of the product. I will update further when I receive the replacement board.Update: Been using the board for quite some time now and very pleased with its performance and versatility. It took some time to understand the controls because there are just so many. For anyone planning on custom water-cooling, I would highly recommend getting this or the quadro as a controller. The controllers built-in to motherboards are unreliable and inferior. They air designed for simple air cooled setups and have very limited options despite their claims. For example, my Asus Maximus Z370 Hero motherboard has a dedicated "water pump header" but it is locked with the CPU Fan headers and can only be controlled by CPU temperature. Since my loop includes the GPU, I want to be able to control the pump speed based on other inputs such as coolant temps and GPU temps. The Octo controller gives me the ability to use whatever input signal I wish and even create virtual signals through software. If I want my fans to spin based on the difference between the air temp and liquid temp, I can create a virtual senor that calculates the delta and use that as the input for fan control.

Most people may buy this as a way to run more fans or add temperature sensors to their system, and it's great for that, but with the AquaSuite software, you can completely offload control of your water cooling system to this little guy.While AquaSuite is famous for it's bells and whistles, you can kind of reverse that and just use it to upload water temperature based pump/fan curves to this thing and never run cooling software on your system again. That also means that, even if you system hangs, your cooling loop will appropriately ramp up and prevent overheating if you aren't there to address it.If you just want a fan hub, save your money, but if you're going to use it appropriately, it's worth every penny.

These things rock. Do it.

This works great, paired with a coolant temp. sensor fans are controlled automatically via coolant temp.A much better option over using the motherboard fan header.The Aquasuite software was easy to setup.Would recommend for any custom water cooled PC.

The product itself is likely great. It came weeks late (well after Christmas). Then I tried to return it to find that I can't because someone opened the box to see what it was and returns must be unopened. In addition, there's a restocking fee?? lol This is a $65 fan splitter that suggests/requires you to purchase additional annual subscription controller software to run and they send it late, limit returns, and charge me to return their late product so they can send it to someone else?Probably a good product, but I would not recommend this particular ModMyMods vendor for this. I don't have any other experiences with them, either positive or negative.

Astounding software.Don’t build without it . Taps into a myriad of sensors . Fan control is limitless . Customization out the wazoo .Great support if you want to go deeper.

Good luck finding a better one.
