Looking for QUIET pump

I need a very quiet water pump. I'm trying to get my system as close to silent as possible, and my current QuietOne 1200 (lol) is by far the loudest component.
I can't afford anything extremely expensive (college starts next week), but up to $50 is fine, maybe a little more.

I run an athlon64 3200 s754 (RBX block), and a radeon 9800 pro (maze 4), both overclocked. Everything's cooled by a heatercore with a very low speed 120mm fan.

If you want more power than the eheims, or if you prefer 12v, then the swiftech 12v pumps are powerful and very quiet.
 
Is there any difference between the swiftech mcp650 and the DD 12v-d4? They look the same, but I can't find specific specs for the DD, so I'm not sure.
I like the idea of a 12v pump, one less cord hanging off the computer, but they're somewhat cost prohibitive. If someone knows where I can get one cheap (used even), I'll probably get it. Otherwise directron has a 1250 for around $65 shipped. More than I wanted to spend, but I can't find anything good under $50. :(

I don't know how quiet it is relative to other brands, but my Hydor L30 is undetectable from 5 feet. There's a small vibration but the pump itself makes almost zero noise.

EDIT: Oh, and I got mine for about $55 or so.

Yes, there is a difference. They are the same model pump from Laing, but Danger Den sells a slightly older, more powerful model, to the best of my knowledge. However, that pump is a bit louder than swiftech's version is. If you are going for quiet, the swiftech one would be the one to get.
 
I think they're both actually louder at 12v than the eheims. I can hear absolutely nothign coming from my pump.
 
Does anyone have both, to compare side-by-side? I dug through my couch and found some extra change, so I'm leaning towards the swiftech since it's 12v and has better head. But if the eheim is significantly quieter I might be tempted to go with that.
Is either really even audible over a power supply, hard drive, etc?

Thanks everyone for the help.

I have the swiftech and it is extremely quiet. It is not audible over any fans I have heard, or and hard drive I own, neither is it audible it I have my window open and can hear the crickets and breeze outside. It is just barely audible in my bedroom with no electronics on and the door and windows closed.

My compaq laptop (Celeron 366) is also louder than it.

I have heard some great things about the volume of the eheims, but I haven't actually heard them in action. However, I can't imagine that you could hear the swiftech running while your computer is on.

Yogi, I thought you had an MCP600, not a MCP650?


The MCP650 is noticably louder than any Eheim, really. But, thats not really saying anything, because Eheim pumps are virtually silent. I personally don't think you would really notice the noise from an MCP650 over the rest of your computer.
 
I have the MCP600, but I was under the impression that they are very simmilar pumps. After looking at the swiftech website, I see that the MCP650 is visually quite different from the 600, so I'm not sure how comparable they are.

Just to clarify, my comments above are for the MCP600 rev2, and noise tests were from about 1.5-2 metres away, as that is how far my bed is from my computer.
 
Yeah, I'm not sure where Swiftech was getting the pumps for the MCP600 from. The MCP650 is a Laing D4 though, which is the same model of pump that Danger Den's 12V pump is. However, it's a newer "version" or something (the wording gets confusing here, as they don't actually classify them as different revisions) than the one Danger Den sells. It is supposedly much quieter, but not quite as powerful.

Dangerdens performs better, swiftecs performs a little less (its almost a tie really, but the D4 pushes a little more) and is more quite.
 
Well, frozencpu has both the MCP600 and MCP 650 for $80. I'm tempted to go with the 600, based on Yogi's comments. But I'm concerned about the 160gph flowrate. Is that really enough, especially with an RBX block?

Edit: 600 is out of stock, same as everywhere else. So 650 it is.
Still curious about the flow rate though.

Ordered my MCP650 around 3:30, it shipped just after 7. Should have it monday, I'll let everyone know how it works.
Now to work out my next project: a BAWLS bottle reservoir. Anyone know the easiest way to drill a hole in glass? :eek: :p

The make bits for glass. Go slow, and use lubrication.

I think DD has a new quieter muffled version of teh D4 now. They are also claiming superior results over the swifty.

I saw a really recent thread about a bawls resevoir... do a quick search, i'm sure you'll find it..

LOL yeah he really should be carefull what he says.

Easy way to decide, go for the one which gives better head. ;)

What about this pump?

it's 12v, and is made for watercooling.......and cost $39....I have 2 sitting in front of me, but i just haven't had time to test them...

You have the new Cadillac of the 12v pumps from what I have been reading, especially if you have two of them that you can parallel or series, which ever suits your needs. You can no longer get the blue ones from the mfg, I D-tek is now the sole distributor that I am aware of, and they are painted or anodized black and and D-tek is taking preorders. I have been following a thread from the mfg on another forum. Would not want to part with them would ya?

I saw that one at dtek, but a lot of people seem to like the DD and swiftech pumps, so I ordered an MCP650. I should have it today.

Edit: Got the pump. Can pumps be mounted vertically, instead of horizontally? It'd be easier to avoid kinks in the tubing if I bolted it to the back of my case, next to the PCI slots, instead of on the bottom. I don't think it'll be an issue, but thought I'd ask.

I cant imagine why it would make an difference to the pump.If anything, you would almost think it would put less strain on the impeller shaft not working against gravity regarding wear.

That's what I thought, but I remembered reading somewhere that they have to be mounted horizontally. So I thought I'd ask. I ended up putting the pump on the bottom after all so I wouldn't have to move my lights, or lose my bottom 3 PCI slots.
CPU idle temp is around 36 C (31 C ambient, our air conditioner's broken :( ), about 15 C cooler than the stock air cooling I've had for the past 2 weeks. Sandra's running now, I'll post load temps in half an hour or so.

Pump is much quieter than my old one, although not as silent as I had hoped. It has a high-pitched whining noise, that's audible to about 15 feet away with the comp running. MCP650 owners, is that normal?

miro
 
hmm, load temps 41-42 C. not as good as i was expecting, but still not bad i guess.

miro
 
the new d4 and the mcp650 are the same from what i know. ive owned the mcp600 and the d4, mcp600 is silent compared to the whine the d4 makes. i put it on a rheobus and it will turn down the pitch hehe. also lowers flowrate but my temps are the same at the lower flowrate.

Adjustable flowrate pumps, hmm interesting.

...eh, not much different than adjusting fan speed. Pump is pretty much just a fan for water anyways. :) ---or is a fan just a pump for air?
 
I'm running a Maxijet 1200. All in all, it's a very quiet pump with decent performance. I honestly can't hear it over my mobo's chipset fan. Of course a lot of that has to do with the manner in which I have it mounted. It has a 3 suction cup base which it sits on and I believe this eliminates any acoustic vibration. I've been running this pump for the better part of a year now and it has been very reliable. With a pricetag in the ~$20.00 range, this pump turned out to be a real winner for me.
