Eheim 1262 and bubble magus skimmer pump both AC pumps and 100% dead silent. Zero hum. Tunze powerheads are D.C. Also dead silent. Jebao WP series powerheads D.C. And a very noticeable audible hum. From the pump motors themselves. Old style ecotech mp 40 D.C. Pump and loud enough to wake the dead. Mag 5 and sicce syncra 3.0 AC pumps and both loud as a lawnmower. That's my experience. Seems to just depend on the pump. Price doesn't appear to have much correlation with noise in this instance

How can something be really quiet and produce a high pitched whine at the same time.
I have received my first DC pump today, and according to the description on the website it should be "ultra quiet".
Oh man what a joke. It has a very annoying whine. Don't know if it needs breaking in but if it stays this way it's getting back.

Received the Jebao dcs1200 return pump today and it produces a high pitched whine. On max power i can hear the whine through the whole house. It's ridiculous.

Thats crazy. I have the 12000 and the 2000 but also they’re both only ran at 40%. Return only runs at 100% when I’m doing a deep clean and I’ve never noticed a whine but that could be because my sump is loud when I’m running it that high.

I can’t speak for DC return pumps. But lots of What I call brushless DC motors have a whine usually at low speeds. Cordless drills, some hvac compressor motors etc. some times the speed controller can make a whine also. I have experienced this with RC cars.

Yeah, my (nano)tank is dead silent other then the fan of my led light and the return pump, explains a lot.
Before i bought my led light all the owners/reviewers claimed it's dead silent, so i bought it and it turned out to be not so silent as they all claimed. I can hear it clearly through the whole room when it's quiet in the house.

I think silent is a relative term. I didn’t realize how loud my last tank was until
I tore it down for the house remodel.
With that said if it says silent my expectations is with everything running on tank I should not here the return pump with doors closed at all.

Harold,
I just picked up the same return pump and it does the same whining sound. Did it ever improve? I've been running mine for 3 weeks now @90% and no improvement in the sound.

No, it didn't improve. I ditched it and bought the Aqua Medic DC Runner 1.3 which is DEAD SILENT.
