I have 2x Aquacomputer's earlier generation Aquabus D5... they are not connecting properly, and I suspect that the Aquabus board is fried on each of them. They run, but only at full power. They are quite old now anyways and probably due replacing. What do people recommend nowadays? A few specifics about my requirements:

1) I have twin custom loops: Loop a) 480 rad and an EK CPU waterblock. Nothing else. Loop b) 560 rad and an EK GPU waterblock. Nothing else. My installation means that there is no room for Aquacomputer's D5 NEXT pump. Besides I don't like all the bling. (Please don't question me on room for the NEXT - I know there is not and I do not want to mod my case further to make room).

2) I've not been on the forums for a while, but I vaguely remember that the Aquaero 6 does not necessarily play nice with all D5 PWM pumps... am I correct in this? Are there any D5 PWM's that are known to be okay with the Aquaero 6? (I can easily and quick cheaply buy Primochill, EK or XSPC D5 PWMs).


3) Would you advice me to just forget PWM / Aquabus and get a Vario and set it to 3/5 or whatever. (Currently running at full speed the system is needlessly noisy and flow speed is unnecessary fast currently)?


Thanks for any advice fellow watercooling enthusiasts.

Ahh thanks BartDude, very helpful.

Thanks guys. Just got back from overseas trip: ordered. I should be able to get my system much quieter with the pumps at 50-60%.

GTXJackBauer: your the guy active on EVGA forums, right? Anyways, thanks for info.
