When did you get that email? I haven't been able to get a response from the seller.

I installed my DDC-1T yesterday and it is loud as hell and I don't know what can be done about it other than sealing it in a very heavy sound proof box. I almost suspect that it is defective and I can't believe that anyone would use these if they are all this loud. Argh, I just want to tear it out of my case and smash it with a hammer, that's how aggravating it is. My case isn't even quiet to begin with. I had 7 1900RPM scythe slipstream fans going full black and I could easily hear the pump over them. A controller doesn't help at all.

Either you have a dud, it's mounted on an unstable/rackety surface or a HUGE air bubble on it. My main rig has 7x GentleTyphoons running 2150 RPM, and the pump sound gets drowned by them (i only hear a faint buzzing when i turn it on, before my fans start going full speed). Heck, my HTPC's pump is completely silent, and on that case i only have two GT's and two Arctic F9's running.

My pump is also connected directly tot he PSU, no fan controller on it. Plus all my fans run at full speed unless i'm sleeping.

My pumps did make a lot of noise if it has air inside. Try plugging it and unplugging it to get rid of the air, worked for me. Also, i got rid of a lot of air by leak-testing for 24 hrs.

Try an Alphacool 5.25" Dual Drive Bay Repack Reservoir Rev.2 it takes care of any air-bubbles.

I can barely hear the my pump, it's inside an SilentBox. I have four fans that are whisper quiet on around 700 rpm.

Thanks for the suggestions. It's not a mounting problem as I've tried different orientations and even just holding it in my hand. I suspect I have a dud.

Here's a video I took of it: http://www.youtube.com/watch?v=hqJcVy41qTY You can hear me slow it down with a controller. The point where it is quiet is when it stops completely.

I can look into the silent box, but it would have to be pretty tightly sealed to get rid of this noise.

They don't make that kind of a sound.
post #197 of 347
In regards to a new PCB, is this something that you guys think would actually help? $10 and some soldering work is not bad if it will actually get rid of this awful buzzing sound. I don't entirely understand what the new PCB actually does for you. Martin's reviews suggest that it will help performance, but I am more concerned abut the buzzing than I am higher pressure.

Edit: nevermind, Martin says that he thinks that the new pcb is actually "buzzier" but then again I doubt that his was as loud as mine is to begin with.

So, the pump outlet feed the larger RAD easily. That's a neat loop order.

It is smile.gif Thanks Bmaverick...
You will receive a payment for another pump soon... I want to add a bit more pumping power before adding more rad surface.
