Laing D5 wery noisy

[grandpatzer]

Before putting case together I carefuly adjusted speed to the lowest noise that could push water though system.

The pump is noisy as hell, why?!

The pump I cut out 3 thin bits of tygon and put as feet, I screwed in the pump to the bottom of case and put 2 thin tygon bits under screws as padding.

There is about 15cm air bubble, It is impossible to bleed unfortunately.

Not a water cooling expert, but pretty sure that's a big problem.

A lot of pumps use the water to cool and lubricate its moving parts, so air bubbles in the loop are bad. Air bubbles will also hurt performance. You need to bleed all the air out of the system.

is the water actually flowing? it doesn't seem like the waters moving.

Move your case around to try and get it out. Seems like there isn't enough water in the loop to get the water flowing

do you have a reservoir? where is the bubble in relation to the pump?

you can usually get most of the air out by tilting the pc in various directions with only the pump running.

cuz you have air stuck in the pump it will be noisey as its priming and chopping the air bubbles.

Once your system is completely bleed, they tend to quiet down a lot.
