Dual pumps noise

[woffen]

Haha, I first read it as you don't want to give us idiots any links, I was like wtf have I said

Thanks for the link!

Much as I hate to link to Aquatuning, found the DDC PWM pump available for sale now.

Informational link only, don't buy from these scumbags!

I see nothing that hints at that being a PWM variant, am I missing something?

looks pretty normal to me

Yup, you're right. Thought that 3pin was a 4pin.

Whoops!

That is what I remember from my old rig. Probably is the xspc dual bay res which cant handle the vibration from two 3.2's.

I like how you switched from D5 discussion over to the MCP355

What about EK dual tops? They are intended to be mounted in 5.25" bays in same manner as XSPC res are, correct? Do they transmit vibrations to the case, or do a better job, or simply the D5 vibrate less than MCP355?

And one fundamental question - atm I have MCP350 with EK top. I'm thinking about dualing. Would you get another MCP350 with single top, a dual top from EK or switch to the D5s (have read the thread from the original post, still have to decide about dual or single top)?

I can't clear the misconception in my head - so the D5s are more silent and DDCs have better flow and pressure, right? Then again, I'm confused about how you guys seem to favorite D5s, I'm under impression there are more D5s in your sigs than DDCs.

Great discussion, thanks.

any other noise would be trapped bubbles which should be eliminated anyway.

You can't always get rid of them all, water always has a little gas dissolved in there, so pumping will give a tiny little cavition bubbles - you can cut down on it massively if you have a completely sealed system though, just put a couple of PSI of air pressure in the expansion tank.

Oh i forgot to mention..

While i was talking to gabe @ CES, he mentioned something about a PWM DDC.
And the way Gabe told me how its configured it seems REALLY REALLY HOT!

Ahem Ahem.

Say good bye Silent King D5.

I only jumped on after this comment

I go back forth between the two types of pumps depending on what setup i am doing. Neither are loud to me and both perform the same to me, but that's not scientific, just personal opinion.

Which one would you prefer in a single loop with high restriction? And with having in mind your response, would that mean that you would choose the opposite if the restriction was low?

Thanks.
