Dual pumps noise

[NaeKuh]

Primochill has very interesting pump housing + reservoir - Typhoon III. It showed pretty impressive numbers, plus you can run dual-loop from single pump, or single loop with much more efficiency. There was thread about that somewhere on XS.

and 3/5 cracked.

So no, we dont recomend stuff that breaks.

Also T3 is being redesigned to fix that problem.

And i WONT be endorsing this product, until a few of my friends have gotten there RMA replacements.

Which means They been stuck with a broken res without replacement for a while now.

Lol. Very nice flow rates internal. Not so nice, but present, flow rates external.

I'm of the group Naekuh is talking about... no res, no rma, almost no response, plenty of water in my case (oh and I'm out some cash too...).

I'm going dual ddc as soon as I can get a hold of an EK dual ddc top with multi-link option. (in the style of EK... damn sexy)

[NaeKuh]

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.

[woffen]

Did he say anything about a time frame?

I like my vario, but it's huge...

PWM ddc's... that's something worth blowing some cash on. Did Gabe give any word on an ETA?

+1


which controller would be the best option to use that ddc with pwm??

[NaeKuh]

no eta yet.

but i saw the pump in his system he was showing off.

Can someone explain the difference between a normal ddc and a ddc with pwm? It must have something to do with you being able to control the PWM one somehow but a little more detailed explaining would be great

first off the connector is a 4 pin and not a 3 pin found on normal DDC's.

I say 3, becuase its + - RPM.
The 4 pin would be + - RPM PWM.

The point in pwm is the pulse the pump, so instead of screaming at 4000rpm's, it would go in a wave from 4000 -> 1400 -> 4000 -> 1400, as the cpu header emits the PWM pulse.

How he had it connected was 2 was a molex, or looked like a molex with standard + - , and the other 2 looked like RPM and PWM headers that went directly to your cpu motherboard fan header.

Thats how you controlled the PWM.

It was really cool, and im sure gabe will talk more about it when he decides to.

[woffen]

Ok, thanks for your explanation. A quick question still, how would if affect the performance of the pump?

[armeniandave]

I agree that system was dead quiet!

I had a chance to look at it when there wasn't
anyone in the room and you couldn't even tell
it was on!

I've built three Cosmos rigs and this was by far
the quietest computer I have heard.

ddc with pwm... to slow reaction time will probably be an BIG issue... might not be a problem for non-overclockers, but why wc with todays silent and efficient aircoolers if not oc ???

Go try and aircool those 285GTX's in SLI, and in silence good luck
I built some very quiet aircooled setups, but they are far from the power of my watercooled rigs !

Yep just like my crazy fans. They have built in PWM and 4 wires. It was easy to setup and control. Right now they are running at 2500 rpm in my system instead of 6000 rpm which is great when I slid open the patio door when it's-30 outside and doing some benchies but definitely not on a regular basis. So using this for the DDC is an awesome idea that will help maintain pump power while lowering noise. Smart thinking Gabe!

basically what a pwm does, it senses load on the cpu.

so if the load is on idle, it will pulse it low.

If the cpu is on load, it will pulse it high.

So your performance will be variable.

This isnt meant for us who go after low temps with high oc.
Its meant for the people who value there hearing more then the delta T of there eq.

Gabe was a great guy, really fun to talk to.
And im really glad i got to meet him.

One thing for sure, you would never of known it was Gabe!

[skinnee]

Yeah, Gabe was quite a bit different than the image I had in my mind.

The leather, studs and whips surprised you too?!? I was not ready for that! j/k

Ok, the reason I'm so interested is I don't like the sound of my two DDC3.2 in my XSPC Dual DDC Bay Res. Put all my fans to low to test how quiet I could get it, but the pumps are really making a lot of noise. Atm I hear them over my fans which I never thought would happen as in my old build when I had the pump on a foam pad I could never hear it.

Guess we will see some reviews when Gabe decides to release these. Thanks for your answers NaekuH

In your old build, you used the xspc dual top on the foam pad too? or only a ddc on a foam pad?

I actually consider those XSPC bay res's as a soft hard mount, prime time for vibration transfer of just about every type.

[NaeKuh]

The only issue i see with the pump is longivity.

PWM cant be good on the pump vs having it run at full load.

I think this is the testing gabe is doing b4 he releases it.
Whch is smart, because the last thing he would want is a massive DDC recall.

Back then I only had one ddc in a xspc res/top sitting on a foam pad and I cant remember it making this kind of noise. The pump was then in the case, now I have two at the front which also of course matters.

I actually consider those XSPC bay res's as a soft hard mount, prime time for vibration transfer of just about every type.

The soft parts that are supposed to keep the vibrations from the pump going to the case are quite thin and hard. Might be that they are doing a bad job at keeping vibrations down. I'd want to change the xspc bay res to something else but don't really know to what I'd change it and if it would matter at all.

Hopefully this works out and becomes another great product on the watercooling market.

[RoadconeTuning]

my DDC3.2 is way quieter than my Yate Loon 1600's on my swiffy 360rad and its mounted on top of a fan with a UN bracket... as a matter of fact i think i had to disconnect every fan in my case to hear my ddc with its xspc top...

pwm might be good for a watercooled HTPC tho

[woffen]

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.

[PiLsY]

Doh!
