Hey all, I've emailed AquaComputer about this too, but thought I'd get some opinions here: I'm having an issue with an Aquacomputer D5 Pump with Aquabus, and an Aquaero 6LT. Beginning about a week ago, when booting my computer, my D5 pump will not spin immediately. The time it takes to start varies - sometimes the pump begins to turn a few seconds after the computer powers on, and sometimes the computer completes POST and loads the OS before the pump starts. In the latter case, the Aquasuite software reports 0RPM on the pump until it begins. When the pump does begin to turn, it starts with a surge of speed, then drops down to minimum, before ramping to 100%, where I have it set in the Aquaero. The pump is powered via 4-pin Molex from the PSU, and connected to the Aquaero via Aquabus and my motherboard via USB. The Aquaero recognizes the pump and can control it normally once it starts. Both the pump and Aquaero are less than one year old, and the pump has recently been cleaned along with the rest of the loop - I don't believe there could be anything obstructing it. I'm using Aquaero Double Protect Ultra coolant. Any thoughts, folks?
