Unusual Laing DDC-1T Ultra Pump Noise
Like the title says, there's a strange noise coming from my pump. At first I thought it was a HDD problem as it sounds quite similar to the noise my Seagates make when you load; that quiet, low but quick, repeated, random arm-seeking noise.
After disconnecting all the HDDs in my PC I confusedly narrowed it down to the pump. Turn off the pump, the noise stops. The res is almost full (400/500ml) and after searching the loop I can't see any signs of an air bubble. According to my fan monitor the pump is running at between 4500-4600 RPM.
Am I being too over critical here or is something going seriously wrong?
