Ecotech Marine MP40w ES operating noise

Funky_Fish14 · #1 11-05-2011, 06:35 AM

I have two MP10wES... My older one is loud enough that it whines when upstairs but I bumped it a little while ago and I dont think I lined it up correctly when I set it up again, because my newer one is only half as loud. I can definitely hear them in the next room though, they are on 100%... it was a bit annoying at first, but I have good ears and low 'annoying noise threshold' lol. It doesn't annoy my folks who hate annoying noises (like the smallest water drip or pump humming), though. Its not obnoxious like loud droning, but its defintely an audible 'whir' as it winds up and down.

Cheers,

Chris

Marine Aquaria, BigAls, & Redcoral. They have mp40s in their tanks.
I have 2 MP60 in 1 tank, and 1 mp40 in the other. If you want to see it PM me.

Aquarium Illusions also has one in their display tank.

In person at a house is probably best thing though for comparison... because stores are umpteen times louder than homes even without people in them.

I have 2 mp40s they are both loud and they cause interference with my tv that is in a different room. But I'm really glad I added them to my tank.

I have 2 MP40's and can agree with Doug/Fishytime... they have a little noise, especially if you use pulse modes, but on Reefcrest or Lagoon, silent.

The noise is the winding up and down, but not that bad. Compared to others and the features and power they offer, nothing can compare. I do recommend them.

Only with a CRT tube tv. The magnets can pull the electrons that are being fired in the tv. But only if it's close enough.

It's an LCD tv. Does'nt do this on my main TV just the TVs in the bedrooms. Bell Xpressvu receiver. Once again, I know it's the MP40s 'cause when the power is turned off to them the lines disapear. I've contacted Ecotech and they say that it's not due to their product. I'm used to it now and it does'nt bother me. Just letting others know.

If you buy used and they are out of warranty and you consider yourself as a skilled tinkerer, there is a thread on RC that goes over replacing the bearings on them to quiet them down. Buy some really good high quality RC bearings from Boca. You'll need a couple tools and a bearing puller to do it without damaging anything.

I have the bearings downstairs for my 1.5 yr old MP40, I just need a bearing puller and then I can do the replacement.

If you do decide to do this, just don't use a screwdriver to pry off the bearings as it will for sure break the magnet.

No guarantees on how much quieter this will make them though.

P.S. In theory you shouldn't need to do this as the product should be engineered to be quiet. But as we all know, they slightly lack in this area...

Hey guys!

A fellow reefer (reefme) invited me to his home the other day for me to witness first hand what MP40's sound like and I was impressed! When aligned properly they are dealy quiet! no jokes. The hallide fans where more noisy than the powerheads. I am convinced that I will own a pair of vortechs for sure! Thanks for everyones imput. This forum is so helpful, I can't emphasize this enough!!! Canreef all the way!
