Quieter than the MH fan? I find that hard to believe. I have 2 of them and at full power I swear I can sometimes hear them from the next floor.

Now at 50%, maybe they'd be really quiet...

I dont know why mine are the only load ones around. They are aligned properly. My bedroom is about 50ft from my tank and when they kick on in the morning after night mode I can hear them as plain as day. I returned one on warranty and after a while it too became noisy. So all 3 have been noisy and all from the dry side. I wont get rid of them though so I put up with it.

I personally don't mind the sound, it sounds like a symphony!!!

I would like to retract my statement below - My new one is very quiet, only audible within the room... the older one has a problem of some sort and will be undergoing return/exchange.

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,

Mp40s are very quiet.

If its loud it's one of these 2 things:

Dry and wet side not lined up perfectly.

And/or

Dry side magnet is rubbing on the rubber spacer. Also the rubber spacer has 3 nipples that need to go into the holes but sometimes they miss the holes and bend and rub against the dry side magnet.

Personally mine are 10's... they have been checked(lined up... no spacers...) ... it is a hardware problem. The good one is very silent.

you're not using the spacer on the dry side? so your magnet is directly exposed to the glass?

The 10's don't have the pin style spacer, they just clamp on or if the glass is very thin below 3/16" i believe then there is a spacer to put in. The 40's have the pin spacer and the 60's have different spacer that slip on.
