I have obsidian 900d with 480 rad on top and on bottom. On bottom I also have ddc 3.2 pwm with ekwb restop https://shop.ekwb.com/ek-xres-140-ddc-3-2-pwm-incl-pump
Pump > gfx > cpu > top rad > bot rad > pump
The issue is vibrations from pump go trough tube to bottom rad and since it is screwed to case it makes low sound like bass because it vibrates side of the case.
How to fix this? Is the tube too short? around 25 cm - Would longer tube dampen more vibrations (but there is not much space for longer tube there)? Before I had only top rad and the tube was going from top to bottom pump and there was no problem with tube vibrations going to rad.
I was thinking to try to decouple rad from case but no idea how much would it help and how exacly to do this.
