Hydor L35: Getting Louder...

post #1 of 7
Thread Starter 
As the days go by, I've been noticing that my pump generates more and more noise. I will be taking a look at it once I do a WC overhaul (new tubing, new fluid and some Swiftech CoolSleeves). The noise is like a Crahhkcharrcrackrrrrrrrr, I've tried letting it mellow for a few, then plugging it back in, and it dosn't do squat. Whats wrong with it? Do Hydor's just start to do this after a while?

Yes. Yes they do.

That is why I have a shirt wrapped around mine. Its now silent! When I got mine it was very quiet, and all of a sudden it started to sound like tiny stones were getting sucked through it almost.

Heh, thats exactly what it sounds like!
There isnt enough room in my case for me to be able to wrap it in something, but I'll see what I can do when I rearrange everything in my case when I get my new mobo and video card.

A long shot, but maybe worth a try--with your system off, try positioning your pump with barbs up, and tap on it.

Mine made similar noises, and it was due to tiny bubbles popping around in there, even thought my loop was well bled. when I tapped on it, bubbles came out, and now it's quiet.

I don't know if other pumps share this problem or not, I am guessing they do, but I can tell you this trick works like a charm. I was ready to throw this damn pump in the trash after I first got it but it has been running near silent since this mod. the trick is to find the perfect "O"ring to wedge into the impeller gap, it has to be kind of thick and fat with a small center, It will be hard to stretch over the magnet.
If you get something too small it will shift around and cause the impeller to bind and you will be taking the pump apart to fix it. It says you can glue it but doubt it would be permanent. It also says you can use rubber bands. I did not try this. Here is the link to the fix: http://www.wc101.com/guides/ViaAqua/

I just have mine in an external resorvoir, glued to a sponge to prevent noise transfering to the desk.
