View Full Version : Silencing the D4 (MCP650)
Well, I don't mind the sound, but I do mind that noise comming out of the wife complaining about it, soo......
I was thinking of cutting up some old mousepads to make a shroud to place around the pump to help deaden the whine of it.
Curious if any others have gone a similar route or tried other solutions to quiet down their D4 (MCP650)?
EDIT:
My buddy at work suggested using old maouse pads to create a shroud around my Wife to deaden the sound of her....

dont have a D4, but does suspending it help get rid of the whine?

hahaha dont let her see thid thread!
I got both my D4s hooked on mt rheobus and undervolted a bit...even a little drop (10v maybe) makes a huge dif. on the whine... and I havent noticed a dif in temps yet... but summer is comming...
careful you dont overheat the pump by insulating it. My d4 is inaudible over my other case fans. I know how you feel about the wife ;) I just keep my rig in my study that she doesnt use and keep the door closed. simple. plus it keeps her out of it :)
Well, we live in a pricey neighborhood in chicago, and lets just say a one bedroom apt cost as much as a 4 bedroom house out in the burbs...
So the Computers are in the living room. I can dial down my fans to near silence, but she actually thinks having them all full blast to drown out the D4 Whine is better.
As far as over heating, It seems like the pump barely gets warm, im guessing its dumping most of its heat into the loop. Either that or the exaust from the front Rad is cooling it down. That was a bti of a concern though, I don't want to have the pump shut down due to overheating, all in the name of silence.
What might also work is a sound wall... Perhaps moutning sound barrier along the side of it might work...
Oh and as far as suspending the pump, it the actually whine of the motor that emits this electric sound. If you've ever played with Remote control cars it sounds like an electronic speed control (which it may very well be, never cracked the pump open, so who knows). The pump sits on a bed of velcro so it is insulated from vibration.
my D4(s) have never bothered me for some reason, but check out mcmaster - they have some sound insulation foam/tiles that would probably get the job done
making a small enclosure out of sound-absorbing tiles with a couple 60 or 80mm fans (to help cool the pump) would definitely be something cool
edit: or line your case with dynamat, which would help with the fan noise as well
I have a bunch of 80mm fans laying around, I was thinking of undervolting one to 7v and sticking that on the back side of a shroud made out of mousepads.
Hrmm... I might go hit the hardware store after work, see if I can come up with something even better. Mousepads I think would work, but would be a bit ghetto. A rigid frame would be nice.....

make a cube out of plexi or 1/4" thick plywood & line the inside with neoprene (mouse pads) or another sound-absorbing material
I'm thining some acrylic would work, you know, ideally, the idea is to just dampen the noise, so an acrylic enclusre might do that all by itself. Throw some LEDs in there and it could look damn spiffy too...
hrmm look sliek I got a project!

ive looked into it, but it seems to silence it, you have two realistic options. One is put it on a rheobus and turn the voltage down a little, but that does impede preformance, and ive heard it impedes it quite a bit. The other option is more simple, get a new pump. It seems more worthwhile to get an MCP350 (DDC) and do the flow mod on it than to spend a lot of money on casing for the D4. If you sell your D4 for like $60-65, then your only paying about $10 for the DDC, which isnt too bad. I dont know how much the 3/8" barbs restrict flow however, but from what ive seen it preforms remarkebly well modded. Or you could just get the MCP600.
You can always create a casing, but I'm the lazy type, and would rather spend $10 on a new pump that preforms just as well and is quieter then to build something. But its up to you, just make sure the pump doesnt overheat if you do case it.

Sell the D4's and buy DDC's. Much better pumps IMO. Dead silent. I had a D4 for 1 day then sold it on ebay.
thing is I love the perfomance of the D4, and building a simple sound dampening enclosure is no big deal take a couple hours tops.
why not try noise cancelling :D put a microphone next to the pump, invert the signal and play it out from next to the microphone. would be realistically near impossible to get it right but could be fun to try. I thought someone had invented noise cancelling case fans which do this but i haven't seen any around
Lol,
I can just see the look on the wife's face....
Her: "Thats going to make a horrible screechnig sound thats going to make the catc freak out and claw my ankels isn't it.."
Me: "No no.."
Her: "Right, cuase you know exactly what you are doing... I'll be in the bedroom hiding"
I had an MCP650 and wrapped it in sound absorbing foam from Mcmaster. It helped a lot. I did however go back and buy an Aquaextreme 50z, and let me tell you, it is about 1/4th the sound level. I can't even hear it at all.

I had the same opionion thrown in a thred of mine and was considering doing the very same thing
But if your not picky bout sound levels is there any advantage to the D4?
is the whine really that bad? i just ordered one and i hate whiny noises. let's hope it's not too bad. :shrug:

It's that bad. I live in a second floor apartment on a busy avenue in mid-town Manhattan and that pump is more noticable and annoying than all of the regular city noises coming from the street. I had to pull it from the system--now it only comes out when I need a spare pump to test somthing, then it goes right back into the box.
I am curious to see how a sound absorbing enclosure works, although just replacing the pump with a 50z is much easier.

oh man, going from MCP650 to MCP350 was the best move i have even made. and yes it's that bad.

I fully agree and yes its that bad, I freaked out when the D4 sounded like my 2 Xeon windtunnels x 4
Well, if the D4 is anchored down tight enough, its pretty darn quiet, however i have it mounted on velcro, which for some reason seems to make it more whiney.
I like having pumps mounted on velcro, makes it easy to move them around when im fiddeling around with my rig. I guess I could just bolt the sucker in.
Oh yeah, I built an enclosure last night (ugly as sin, hence no pics) and it really didn't do a whole lot.
Well i thought i'd revive this thread. I have a cm stacker for my new project which is waiting for me to finish my finals before i start it. however i couldn't help but do a little bit. I got an extra 4-in-3 device for the stacker to put my d4 in and i thought i should try to sound proof it a little so here's what i have:

i used some akase sound damping stuff and lined the inside. I had to make some holes in the back for the fan to keep the pump cool a bit. i won't get around to actually putting the pump in for about a month but it's a perfect fit anyway. I'll cut a hole in the top for the outlet tube and then i'll have another piece of soundproof stuff covering the front with a hole for the inlet tube
haha, i fired up my d4 for a leak test and is really quite loud. i hate whiney noises with a passion. how do you think the pump will perform at 7v?

I highely do not recamend under volting such pumps !.
I'm probly going to buy a DDc & A 50z Aqua just trying to find one less then a 100+ Canadian

care to elaborate on that statement?

Well, the Laing specs say the Ecocirc pumps will work at 6-24v for the 12v models, so at 7v it should turn on. But, there is no way it can perform well at that voltage--even a marginally restrictive loop would bring it to a standstill. If the pump is new just RMA it for being too loud. Or, if you've had it a while, you could either keep it as a spare (what I did with mine) or sell it in the classifieds. The AquaExtreme 50z is a much quieter pump with similar specs and would make a good replacement.

Same as why I would not recamend undervolting it as it'll be hard on the circute as well generating less torque
I loosened up the tubing going into and out of the pump, so it could basicalyl rest freely on the velcro on the bottom of the case, and guess what, that made it quieter. I just added some slight longer tubing and reduced the bend radiuses so their wasn't as much stress on the pump from the tubing.

My D4 is actually pretty quiet. I cannot hear it over the Raptors (I'm running my Panaflos at 7v and they are very quiet). The D4 is not attached to anything (other than the hoses, of course!). It is just sitting on a piece of foam mousepad on the bottom of the case. It is actually laying on its back, with the inlet barb pointed straight up. I'll get a pic when I get home tonight.

well befor I removed my Array I couldn't hear it, but in the quest for quietnes I removed the Array and now the pump is geting on my nerves ! I have it wraped up in foam, I'm hopeing once I'm completed my main mod to an old 386 case it'll be in audiable
