Great success! Did this test setup and it works like a charm. Super impressed with the QUADRO software as well, a bliss to set everything up just the way you want it.

Thanks Speed-VI, That meanwell power supply looks good, but too advanced for me. I'm not savvy enough with electronics to take advantage of this option, and I'm happy to spend more money on my build, if it means spending less time, and less risk things going wrong for me. I'm using the QUADRO not the OCTO, but hopefully it will work as well. It should arrive soon so I can test over the weekend. Will report back on how it goes.

Thanks Hufeisen, That's a very good point! I had not considered how the PSU will turn on without a motherboard. I'm planning to run the setup via a Master/Slave extension lead, (like this )so when I turn on the projector, the power supply gets turned on automatically. Would that work if I get the plug you linked?

I see it! Thanks Taubenhaucher. That seals the deal for me. Thanks for answering all my electronic newbie questions.

Thanks Taubenhaucher, I don't see a molux connector on the Be Quiet 300W SFX model you linked? I had a look at their site and they have a diagram for the cables, but unless the HHD is also a molux I don't understand if it can work with the QUADRO?

Thanks Taubenhaucher, Now I understand what you meant with 12V AND 5V. I will get a computer PSU then. I assume most or all PSU's will deliver both 12V and 5V. Considering it will only power the 4 fans, would a 300W PSU be enough? Like this one ? Much appreciate the help!

Thanks Hufeisen! Good to know! I'm planning to plug it in my computer only for programming and testing. When I have the settings I want, it will go in the hush box by itself, no USB or LEDs connected, only the 4x140mm Be Quiet fans and the temperature sensor. I was hoping the 12V 5A Power Supply would be enough, but if not I suppose I can get a normal PC PSU, then I don't need the molex adapter either. Maybe something like this PSU ? Its just another fan in the case, which means potential more n...

Thanks Taubenhaucher! That's great news. I would like to set the data, remove it from the PC, and then run it with the sensors as you say. If I can find the right power supply it sound like the QUARDO will be perfect. What kind of power supply will be sufficient? I would like to run 4x140mm Be Quiet Silent Wings 3 fans via the QUADRO, the fans are 3.6 watts each. FANS This is the power supply I was planning to get (with a molex adapter): Power Supply I'm not knowledgeable about electronics, so w...

Hi, I want to use the QUADRO fan controller to run 4x140mm fans, powered by a 12v 5a power supply with molex adapter, to use as cooling for a projector hush box. Is it possible to setup the QUADRO fan controller on my PC via USB first, choose the temperature setting via the software, then unplug it and put it in a box by itself? Does it "remember" the settings and work with the USB unplugged from the motherboard? I've looked into many fan controllers and this seems to be the best, so would love ...
