Yes, the San ace is working fine. It is looking like I must use the supplied controller for quiet operation, dang it Thanks for your time and help!

Pilo, when the setting is on power controlled, the fan just stops at anything less than 6.6v which means I can never get the fan slower than around 1270rpm The fan specs should allow for 500rpm@ 5v I have tried it with and without the shorting loops with the same result. Today I attached the supplied fan controller to the third fan, and connected the rpm wire to the aquaero 5 and it does indeed allow the fan to go at 500rpm, here's proof! I don't know what voltage this is unfortunately [attach]4...

Thanks for the suggestions guys! EnigmaG, I have tried the settings with each of the 3 ap182 fans in turn, and they all do the same thing on any of the four channels Pilo, I have the waterblock for my aquaero attached with the supplied thermal pad, integrated into my loop. I created a graph to monitor the temperature of fan amp 3. At 6.6v fan amp 3 is settling at about 37.5 degrees. Fan amp 1+2 runs at about 45 degrees with two ap182s running at 6.6v which I think leaves me plenty of headroom, d...

]I am currently (for demonstration purposes) using a curve controller with the first two ap182 fans, rpm controlled. I have set a limit on the hold minimum power to 6.6v to keep them running. I have tried using a 'constant value' of 100% and using the fan power sliders and can confirm that the fans simply stop when the voltage is less than 6.6v. As you can see in the picture, I have 3 ap182 fans. The first two are running from the curve controller with a 'Hold minimum power' of 6.6v and so are r...

Right, I have tried the settings you advised, but unfortunately they do not resolve the issue. With further testing I can see that anything less the 6.5v and the fan stops, which gives me about 1250 rpm at a minimum. The current shown for each fan at this setting is wildly fluctuating between 0.11a all the way to 0.94a. Tried it with both RPM and Power controlled. Looks like I will have to message Silverstone and ask them about it or just use the rheostat provided

Thanks for the speedy reply guys, but that is how it was at default, power controlled. Tried it with RPM controlled as well with no benefit, including setting a minimum voltage with "hold minimum power ticked" Just read the review of the AP182 here http://www.overclock.net/t/1317037/silverstone-ap182-review The reviewer had some problems with his AP182s and a fan controller, causing squealing. He was using PWM however, I am not Heres' the interesting bit from the review "The FC5V2 uses pulse-wid...

I have the aquaero 5 with optional waterblock, running 3 AP182 fans from channels 1-3 respectively and a san ace 120 on channel 4. Fan amp temp sensors are fine (45 degrees) The problem is that I am unable to run the AP182 fans at anything lower than 1300 rpm without the fans constantly ramping up and down or just simply stopping. The current is wildly fluctuating all the time. Has anyone else tried controlling any of these fans with the aquaero?

I seem to have blown my aquaero 5 pro and mps flow sensor by incorrectly wiring the molex that supplies its power, does aquacomputer offer a repair service at all?
