I've been running my new Aquastream Ultimate for about a week now and have been having some issues with it since last weekend when I attached it to my PSU. I had it running on a separate powersupply before for leak testing.
Some of my findings so far:
- buttons next to the display barely work and just flex inward (irreversibly bending the plastic).
- LCD display is not fixed in place securely
- Pump has never gone above 5000rpm and about 350mbar according to the aquasuite software.
- I've never seen power consumption go above 8 watts even when I set it to maximum rpm.
- Since last weekend the pump will randomly drop to about 2500rpm for a second before going back to ~4900rpm about every minute, sometimes faster. This produces an annoying and loud vibration. Setting it to an rpm below 4850 mostly prevents this from happening. While all this is happening voltage never drops at all, both the Aquasuite and the PSUs own monitoring software confirm this: rock solid 12V.
- Only found out recently that temperature control feature, which was one of the reasons I got this pump, is hidden behind an extra price on top of an already pretty expensive pump.
I'm starting to regret my purchase and if most of these issues can't be fixed I'm considering returning it to the webshop I bought it from if they'll still have it back. I've already sent an email to AquaComputer about the rpm issues but haven't had a reply yet.
