The 3 pin aquabus cable for the D5 is (black/red/yellow) and the cable for the flow sensor is (green/yellow/orange).

Are there diagrams anywhere showing what color cable is for what?

the color of the cable does not matter as long as they go to the same points on each connector. you an use a fan extension for the D5 aquabus and a fan y splitter to join the D5 and the flow meter.

I just got the passive cooler from PPC. It looks great other than a missed anodized spot but that won't be seen so no biggie.

Mine came in last week, fortunately no missed spots . . . & PPCs pricing was excellent . .

I added the passive heatsink for the 5 series in place of going to the waterblock, . . .

Seems to work out well . . just need a bit of 1.5mm thermal pad, or some 1mm and .5mm together with some TIM.

The same screws that come with it for the waterblock work fine on the passive as well.

I may go that route depending on how hot the components get at low PWM output.

Darlene if i connect 19 PWM fans + 3 rpm fans + 1 D5 PWM pump to an Aquaero 6 , will i need the passive cooler ? rolleyes.gif

Only at low PWM signals will you generate enough heat for that to be an issue. But your bigger problem is that the D5 PWM doesn't play well with the vanilla AQ6 as Darlene has found out through some weeks of experimenting. She just finished a prototype PCB that could help out and I am sure she can explain this further.

PWM doesn't produce more heat at low duty cycle. That's precisely its advantage over voltage reduction.

Picking up where the others already mentioned . . .

The A6 doesn't work with the PWM D5 as it comes out of the box.

The PWM D5 doesn't exactly follow the Intel PWM standard with regards to the pull up resistor on the PWM line to 5V.


The PWM D5 also only runs at 60% speed with no PWM signal, instead of the usual 100% that comes with a 5V pullup. . . . . Seems to be a design trade-off on their part.


The 19 PWM fans, as long as they are not Corsair's PWM fans, should not be a problem, as long as you use appropriate splitters to power them from the PSU, and only send 1 tach line from a group back to the A6 channel controlling it.


The 3 voltage controlled fans, again assuming commonly used PC/rad fans, should not be a problem on 1 channel set for power or rpm control.


The A6, like most controllers, becomes the warmest at mid speeds with voltage controlled loads, when that channel is more heavily loaded.


For the capable DIY'er . . .

While not as optimal a solution as the active component based solutions, this is a workable solution to the issue of having a PWM D5.




I've tried it on a single and a dual D5 setup and it works satisfactorily with pullups optimized for each case, and it's dead nuts simple, though not exactly elegant.

At issue is that the D5 needs a fairly "strong" pullup, (lower resistance) . . . while the A6 works best with weaker pullups, (higher resistance).

It would seem, although I can only speculate, that the A6 has some protective resistors built into its PWM control to limit current in an unanticipated situation.


The active component PCB solution offers the best of both worlds; the A6 sees a weak pullup, while the electrically independant D5 sees a stronger one.

Well i'll use a normal D5 pump then , i'm glad i didn't spend any money with a PWM D5 pump thumb.gif

Ups...i've bought the fans already and they are corsair 120 pwm fans mad.gif ,yes i'll power the fans directly from PSU and plan to divide the 19 pwm fans in 3 groups using Swiftech 8 way splitter (sata).

Am i stuck with the fans if i want to control them with AQ6 !? or they just produce more heat than other PWM brand fans !


I was about to order a AQ6 ,now i'm confused...

the corsair fans dont use standard for the PMW signal. I will let It Diva explain more. get the AQ6 just need different fans. sell those and get a different type
