Water pump noise

[mudshot]

Hi
I was a bit premature with my last thread about how quiet my new pump was.....its as noisey as the old one now.

I have taken it out and tried it in a bucket and its quiet but the moment it gets in the system ie blocks and radiator the noise is very apparant.

Tried flushing out the system with automotive rad flush but no good.

Has anyone come across this problem before?

My next action is to get more tubing and try different arrangements.

Bit stuck now for a soultion.

What pump are you using?

if you're using a hydor pump, then the rattling and noise is going to be there forever; those things have a reputation for being loud and dying because of the poor design.

if you're using a swiftech, danner mag, or anything that looks exactly like those, have you run those without any liquid? those things aren't supposed to run without water, and they can die in a second or less without water or permanantly be noisy as a consequence.

if you're talking about rattling in the case because of the vibration, i recommend a big slab of neoprene foam to cut the vibrations down. it's the cheapest way and most cost-effective way of doing it.

Its an Enhiem 1048 supposidly the "one " to have

It was fine for a week, then added some anti algea and next time switched on the noise started.

Have taken it apart and run with no load ie pumping water from and back to a bucket and is quiet so not the pump.

Flushed the system out several times, so no blockages apparent but could be furred up radiator.

Must have something to do with the flow.

I have pump out, resivoir, radiatior bottom, radiator top, CPU, Chipset, GPU, pump in.

Going to get some more tube bext week and try different configurations.

Will post pic later today

the only thing i can think of now is the anti-algae. the stuff you're using might be a particulate substance (like, it has little particles). it can possibly mess the impellar and the parts connected to it, causing the noise. nothing you should worry about just yet. btw, what "anti-algae" stuff are you using?

Flushed out the system several times

Tried screencleaner/water/distilled water gone through 5 litres

But

When the pump is on its own ie under no load its quiet

Going to strip it tommorrow and see if anything is amiss in the pump

cheers for the help
