Hi everyone,
I have an Aquaero Revision 4 with Powerbooster. According to aquasuite I am up to date with everything. 422 FW 4.69.00 Aquasuite.

I have two Aquastream XT Ultras powered independently. Connected via custom Aquabus cable.
TubeMeter also connected to aquabus inside aquatube separate power connector.
High Flow meter connected via 3 pin cable.
Two Inline temp sensors + the 4 that came with aquaero.
Aquaero is connected to standby power. Relay used to turn off the power switch. Jumper set to standby power.

Dual LED connected.

Channel 1 has two Coolermaster MegaFlow case fans connected.

Channel 2 has another two Coolermaster MegaFlow case fans connected.

Channel 3 has 3 x Coolink SWiF2-120P fans. Only 3 pins connected.


Channel 4 has 2 x Coolink SWiF2-120P


Everything seems to be working fine except channel one will not drop below 70% rpm no matter what the power input. The behaviour is the same no matter which set of fans I connect to channel one. The initial rpm test runs the fan at full power and there seems to be a direct correlation between the power and rpm except it will not go below 522rpm with a max of 750rpm approx.


I only have the case air fans attached to this channel at the moment so its not a massive problem but it would be nice to slow the fans down a bit further as they are the noisiest part on my rig.


So my questions to the aquaero owners and the support people is:-


If you have the same or similar setup as me can you set RPM or power directly on channel one to zero via aquasuite and do your fans stop?


Is this possibly a software bug?


Could channel 1 having the extra power for pumps cause the power calculations to be incorrect for fans?


I have attached the graph from aquasuite showing direct power set at 100% 50% and 0%.


Any suggestions?


Cheers

Hi Shoggy,

Thanks for the quick reply.
I have only just finished this setup as I have been waiting for parts to arrive and only filled the loop last week.



It was only when I was assigning sensors to fans and getting the temperature ranges correct that I noticed Channel 1 was not stopping.

The only things that have been connected to channel one are any of the four combos of fans listed above. I have not had any problems with channel 1 Overload as far as I am aware? All my fan combos are below 15W and total < 45W at full load. 25W has never been near channel 1.

It was bought in Nov/Dec 2010 but only fully connected up in the last week (All fans, sensors, standby power etc.). Never had any issues during setup.


Do I need to return it for repair or can you send a replacement (part?).


Should I contact your support department?


Cheers

Hi Shoggy,

Is soldering required? If yes how much?
