Good day,

I've put a loop together back in November, 2013, and it has run without problems until a few weeks ago.
I've got a Koolance PMP-400 (DDC-1) with EK Acetal Top, connected to a Lamptron Rheobus. I'm running the pump at 8.5-9.0V, which produces ~0.9-1.0GPM of flow.

When playing CS:GO, the coolant flow has stopped (I had AIDA 64 open on a side monitor and saw GPU temp jump to into 90's). After turning the "pump knob" on rheobus all the way to 12V the pump has restarted and kept running. Since then I've tried bringing the pump back to 9.0V and it seized again after some time. The fist thought was an air bubble stuck around the pump, so I thoroughly re-bled the system - no luck, the problem persists.

Has anyone had similar experiences? Any suggestions for fixes / further troubleshooting? The loop layout below:
