in my quest for a whisper-silent PC, the vibration and noise from my cheap 1000l/h pump are the biggest problem. I did that kind of teflon-trick.
yesterday I made a wooden housing for my pump: I used wood that was 2cm thick and made a box. the pump is attached with bolts and nuts to the base, but it only holds the pump in place (the pump isn't clamped to the base!). between the bolts, pump and base I placed some noise-isolating mats. there's also isolation on the inside of the box. there's a big hole in the front for the intake hose and one in the top for the outtake hose. the top can be removed.
but it isn't perfect: if the hoses touch the wood, or the pump isn't in a certain position it makes noise. the hoses don't touch the wood thanks to some of those noise-isolating mats. for the pump: I don't know. I keep tilding and rocking the housing until it's silent. same for the top piece of wood that's resting on the sides of the box. I placed the top on a metal mesh. the mesh is bigger then the box so it lies on the sides of the box
it certainly reduced the noise: now the pump doesn't make a lot more noise then the rest of my system. but it's still noticeable, so I want to go further.
as I need to mess until the pump is silent, can you give me some advise how I should fix it?
should I...
- tighten the nuts, so the pump is fixed on the bottom/screws. with some isolation between everything offcourse
- attach the pump to the case with elastic bands, just like they do with HDD's to reduce the vibration? that way the pump doesn't touch the case and conduct the vibrations to it. I'll also have to attach the hoses with elastic bands so they won't touch the housing either. a good idea, or not? it might reduce quite some vibration, but it will be hard to handle the pump/hoses. won't the water and hoses conduct all the vibration then?
other ideas are always welcome, the more silent the better I sleep
