Massive Radiator Box Controller Help

post #1 of 6
Thread Starter 
Hello fellow water coolers!
As the title suggests I am searching for a controller or series of controllers to manage all of the hardware. The hardware is as follows:
2x EK XTOP D5 PWM Pumps
32x Delta AFC1212D -F00 PWM Fans
Koolance inline flow meter
Koolance inline temp sensor

The problem I've run into is that the fans are PWM and it seems as if there is little, high wattage PWM controller support. Since the Radbox will be a completely separate unit, (power-wise) the controller needs to be independent of the computer. As far as I have researched, the best option may be the aquaero 6 Pro. Because of the fan wattage, (6.25w per fan) I think I can get away with using a 4-1 fan splitter with a molex. This reduces the power consumption load to the controller but I have no idea how many delta fans I can put on one PWM signal and have them respond.

I'm running 4 480mm rads in push-pull so it would be nice to at least have those on the same channel. I expect to run the fans on around 50%. Both pumps will be running at the same time, I can't give a power expectation due to the size of this loop. I'll be using the flow meter to dial that one in. The power will come from a spare EVGA 750 G2.

I accept the fact that 2 controllers may be the answer here due to the need for the flow meter and inline temp sensor. I'm open to the option of a custom made PWM controller but it needs to be consumer ready for simple folk such as I.

Hopefully didn't ramble too much or put this in the wrong place for my first thread here. Thank you so much in advance for any suggestions!

Since all your fans are PWM, can you power them directly from PSU, and only feed the PWM signal from the controller?

I have 24 fans in my build, and all are controlled from motherboard headers. The most fans per header is 8, and it works fine. Controller should have headers at least as capable as motherboard's ones.

With high quality fans like Delta's you should be able to string a fair few onto the same PWM signal before you start getting problems like reduced range of response. I have had over 10 EK PWM fans on a single Aquaero header without any problems. So, you may be able to put all the fans on 3 channels of the Aq6 with power straight from the PSU and the pumps on the 4th header in the same manor.

This seems like a lot of cooling to bother with variable fan speed though. I would be more likely to just go with fixed, low speed fans because with that sort of space upping the speed just doesn't have that much effect compared to when using relatively little rad space.
To me that is the beauty of brute force huge surface area cooling, it becomes simpler in a way.

Edit: Just realised the fans you are talking about. 32 x 3400RPM fans on 4 rads? Is this a backup for Fukishima's cooling?

Thanks for the quick replies cmpxchg8b and Jakusonfire.

As far as feeding a PWM signal from a controller is proving very difficult. I don't have much talent in the electrical circuits department. Premade controllers are for the vast majority, 3 pin controllers via voltage modulation despite saying 3-4 pin PWM. There are many standalone single pot PWM controllers on EBay and related sites, but I'm not risking making another bad purchase due to a lack of knowledge.

8 fans is perfect for me regarding how many can run on a single PWM signal.

I've been looking into the Aquaero 6 off and on for a while now and I can't decide if I can run the whole system off of it. Just not so sure how to do it. How many 4 pin header channels does it have? Also. I could never find out if it requires a host signal from a mobo header or if it generates the signal?

You got that right thumb.gif. Would it be a better idea to say screw it and only use 3 pins? I don't mind doing that but I am concerned about reduced lifespan and potentially increased noise ( and yes they are rated at 46 dB). A Lampron CW611 and a Lampron CF525 are sitting on the work bench staring me down...

Ha, if they pay I will build it. This is just an custom wood rad box build, nothing flashy
. Hopefully I'll start a main thread about the build as soon as I get the final kinks worked out. Despite any sponsors, the build is focused around EK parts with a little BitsPower sprinkled in. I don't want to give any more away but this one took a while to save up for biggrin.gif

The Aq6 has 4 fan channels. It is a self contained computer system in its own right. The USB connection and software are just a monitoring and programming aid. The Aquaero can be happily used without ever connecting it to a PC if needed. It is just more fiddly operating it through 3 buttons and a menu system but totally possible. Once its set up it can be left to its own devices.

You seem to be creating more problems than there needs to be. You should be able to run the whole system with an Aquaero but some small compromises might make it easier.
For large numbers of fans voltage controlled models can be a simpler solution. Trying to use voltage control on PWM fans would on most fans normally mean a reduced range of speed control as their min voltage is higher then other fans so the fan will stop before getting to low speeds. If you already have the fans then your options arent great but then Deltas aren't your average fans so a bit of experimenting might be worth it.

Then it looks like that is the best option, thank you so much for the help. This problem has been killing me for a week. All the parts are washed and ready to go. Just waiting on the controler so I can start construction.
