Phew, i'm glad i went for the 50Z instead of the mcp650. :)
lol.. I wont lead you astray.
and where can i find that 50Z in europe?
Just replaced my DD 12v pump (MCP650) with a MCP600 and all I can say is WOW it is WAY quieter than the 650!!! That buzz of the 650 was getting annoying!!
You can't. ;)Quote:

If I would have known about the sound issue I would have gone for the 50z when I bought it, but you know if it works, I'm not gonna fix it!
Dumping more heat onto water? I don't know... (wrapped = no airflow to cool pump really well)Quote:

My aquaextreme 50z (MCP 600) is too loud for me. It makes my case rather noisy (it might be the vibrations more so than the actual noise from the pump). I have a Laing DDC (MCP 350) coming tomorrow to replace it. I really want a very quiet, but good to excellent performing system.
Semi-unrelated side note: With the MCP 600 and my HDPE reservoir the water splashes in the reservoir. That noise also drives me nuts. I've got a DD fill port coming to replace the reservoir as well.
No pump will be quiet without proper vibration mounting. MCP600 is very quiet and not readily detectable vs MCP350 in cases deemed quiet. How is MCP600 mounted? If you followed the instruction given... bad. No metal should contact case, no screws in unless you grometted (even that is not good enough). Put big sponge type thing or... sorbothane (if you can find it) underneath pump. Make sure you don't make tubing so tight that it transmits all vibrations. You will have same problem with MCP350 unless above steps are taken.Quote:

Just use the doublesided tape. Key factor here is "isolating" the vibration from case. By tightning the screw you effectively joined the thing. Making whole case vibrate. One quick way to test is touch the furthest away part of case from pump and if you can feel it, that's guaranteed noise. MCP350 vibrates slightly lesser amount but without proper isolation, it will.
(I've got 3 watercooled rigs atm. 1 with 2 mcp600, 1 with single mcp600, 1 with mcp350, the ones with single pumps are for quieting the system more than anything else and they do sound similar about a foot or two away... not noticeble beyond that distance due to the fact they are in kitchen and living room which do have fridge in same open evnironment... loudest thing around there)...
Jinu117: you're wrong on the vibration... I mounted my mcp650 and mcp600... with 2 screws.. the reason why it doesn't vibrate is because the bottom plate is paded with a soft foam to absorb the vibration that the pump will gives out. I don't know about you but I like my things secure...
jinu117 & etekberg,
I'm still not entirely set on MCP350 or 50z. I want quiet. That is the #1 goal. What are your experiences, jinu, with both pumps concerning sound?
etekberg, same question once you get the 350. :)
TIA
Well, my dangerden order came in. I opened up the pump box and surprise, it's a Laing D4 pump, and not the DDC I ordered. The also left out the tee i had ordered (bad DangerDen bad...) but I bought one from Home Depot instead.
So I did a side by side comparison of the 50z and the D4 outside the case similar to the video. As expected, the D4 definitely has a potentially annoying whine to it. Suprisingly, I noticed that that the 50z vibrates a lot more than the D4. When I held the 50z in my hand it vibrated my arm up to my elbow. The D4 in comparison vibrated very little. Maybe the D4 is better balanced?
I wound up suspending the 50z inside the case with some ghetto zip ties and I ditched the reservoir in favor of the fill port and tee line. The tee line fixed the splashing noise from the reservoir. The suspending of the pump got rid of the vibration noise entirely. The only unwarranted noise left is the noise from the air in the lines resulting from the tee line. I'm hoping it goes away after a few days. Even if it doesn't it is still a lot quieter than the splashing water in the reservoir it replaced.
I also switched to the McMaster 7/16 inch ID hose. A much tighter fit and easier bending than the 1/2 inch ID clearflex I used before. Not to mention a much better price :)
All in all I'll probably just keep the 50z in place. I can't imagine the DDC being appreciably quieter.
