Bought a flow sensor ( 53068 ) a week ago and mounted it yesterday. This morning I noticed it's started to make a clicking noise which is quite irritating.
Should I contact the shop where i bought it (Aquatuning) or should I contact aquacomputer?
There are old threads about this issue but they all over a year old, I thought aqua computer would have fixed the issue by now?
I've mounted the flow meter is horizontally which was the fix I saw in the old threads but it's still making the noise.
Been using it for a few days now and the clicking noise is not constant, it comes and goes.
Friday evening I did a few stress tests; raising and lowering pump speeds, running Prime95 to raise CPU and water temps etc. and some gaming. It was than I noticed the clicking noise. It was so loud you could clearly hear it even though my GFX card's fans were at full speed. (still waiting for a water block for the GFX card)
Saturday morning when I started the computer the clicking noise was gone. After leaving it on for 2 hours at idle it was still quiet. Saturday afternoon I did some gaming and the clicking noise came back although not as loud as the day before.
Sunday morning, booted computer and once again no clicking noise. After some gaming it was back. Tried lowering pump speed from 200 L/H to 120L/H which did have a positive impact on the sound level of the clicking but it was still present.
My conclusion is that the clicking noise seems to be related to water temperature. The loudness of the clicking is, not surprisingly, related to flow rates.
At 28 degrees C there is no clicking noise but once the water hits 33-35 it starts.
I could go for a MPS Flow 400, but the High Flow has got good reviews since it's so accurate. Also, the MPS has USB etc. which is useless to me since I'll connect it to an aquaero anyways.
Edit 2:
I was wrong. The clicking is there at 28 degrees as well so it doesn't seem to be temperature related.
