interesting

[Erklat]

If I interpreted correctly, the only thing we get is that housing - like them guys of Swiftech think that anyone
sane uses MCP's with their stock top. On the other hand, the comparison with some state of the art tops
available is the thing I'd love to see.
Plus, with this improvements, it's head pressure is still inferior to that of DDC 3.25 at least according to the test WL did.

So more or less the improvements are of the cosmetic nature rather than performance oriented?

There were some posts related to it in this thread. But yes, interesting and promising pump.
Erklat: this swiftech top still is better then one for original Laing DDC 3.1/3.2 (for MCP350/355 pumps). And this pump is SILENT/you can feed it from motherboard (due to PWM). At 50% power it performs almost as good as D5@speed5.

What would happen to pump if I'd combine the wires via molex to feed it with 7v for example?

You don't need to do the 7V trick because you can connect it to your MoBo and control it via the CPU PWM fan header.


...and sorry, but I don't think I'm paying $110 for a pump.

Waterlogged: For apples to apples comparison imho one has to add up to price of MCP355 some third party top, and only then price difference for this PWM variety should be judged as worth to pay or not.

[Erklat]

Don't MCP350/355 also have PWM header allowing them to be controlled? I asked theoretically about 7v trick. But in practice wires aren't so full of
crap where bioses are

Yeah, it's expensive as hell. So in the end we will all be waiting to see how this top compares to the others

True but, if the new PCB models can be converted to be PWM, I can get a 350 from Newegg for $60, do the mod and toss any of the 6-8 tops I have laying around or leave it stock (I've been know to do it ).

No, they only have the 2 power wires and a RPM sense.

[Church]

Standart DDC pumps have normal analogue power from 2 wires from 4pin molex + 3pin molex with one wire for rpm / tach monitoring. In one variety (koolance PMP-400) those two for power and rpms are united in single 3pin molex. There is one place to solder wire at rumoured to be for pwm, but noone has proved possibility of such mod yet and i'm guessing it's not in business interest of swiftech for Gabe to confirm that possibility as true or not.

It costs more than what I paid for a MCP355 + XSPC res top. I think I can get more out of that combo than 35x

[Church]

And what if you add to price of 355+top price of some rheostat/controller aswell?
Veterans of LC like Waterlogged aside, for LC first timers without big set of LC parts in stash from old builds arround, pricing for these pumps imho is reasonable. Of course, i hope for someone to prove possibility of PWM mod soon

[Hondacity]

i wonder if this thing grinds less...

if you guys liked the gt fans.....you'll certainly want to quiet down your pumps ...

gabe where and when can we order this?

If you are buying a rheobus, you are not using it just for the pump, so it's not really fair to factor it's cost into the total cost of the pump

How would the DD DDC 3.25 pump compare to the new one? Is there a review out there comparing a 3.25 to a 3.2?

I'm looking to snag 2 pumps NOW for a EK dual pump top.

Is a 3.25 much louder then a 3.2? Could one lower the voltage to a 3.25 if need be?

Or should i just snag 2 3.2 pumps?

Hanging pumps with elastic shoelaces work wonders for quieting them down

This is this is the only direct comparison I'm aware of. The data does leave a little to be desired but, I did the best I could with the resources I had at the time.

skinnee is working on a more thorough test ATM.

[Erklat]

Since WL stated that old types have only rpm sense, you're left only with wire tricks.

I'd get 3.25. I doubt they are noisy. It boils down to whether you are sensitive to the high frequency pitch they produce which
might get emphasized with the dual top. Each pump with dedicated top provided like quieter solution. There was this bloke from
Luxembourg who stated he ain't going to dual tops anymore back in December.

So as I see it:

pros: PWM controllable thus potentially quieter, custom top is no longer a 'must'
cons: no real performance improvements, absolutely ridiculous price, there is a chance custom tops will still be better.

[Church]

Many people have noted that most of pump noise can be quietened down by doing two things - dumpening vibrations with something like shoggy sandwitch or petras gel stuff (not too aplicable for pumptops integrated into bay res) and to prevent extra noise from air bubbles hitting impeller by completely bleeding from air loop (sometimes it's not done completely and sometimes big flow might reintroduce bubbles via whirl in reservoir, so some extra steps/countermeasures might be needed, eg. turning rad upside down to get air bubble out, or putting some antiwhirl inserts in reservoir, and/or topping water level in reservoir). Some noise might stay anyway, and of course 3.25 is noisiest one DDC as it's most powerful (maybe apart from DDC2).

Thanks for the read!

Now to figure out if i wana grab me 2 3.25 pumps or wait a week+ for the new 35X model. Was told by a reseller that they hope to get there order in a week.

[Erklat]

Unless you are trying to spit $220 + top price, 3.25's for sure.

Thanks for the info.. Yeah i always make sure to bleed out the air. Its always comical to tip a huge MM case on end to end to get all the air bubbles out! hehe. Its gona be even funnier with my new MM Extension Ascension case. Damn forgot my old former case mod made out of lubic that was about 4 feet tall. That was a real chuckle tipping all over the place to get the air bubles all out. haha

Nice, did you post some picture on how to do this earlier? I'd like to try that..

I'm curious to see what the vendors price these at...MSRP vs vendor prices vary quite a bit sometimes.

u will fry your psu, seeing how the psu has no real 7v rail, and needs to mickey mouse the ground with voltage for 7v.

[Martinm210]

Ok..I think I get what needs to be done to mod one...pictures skinnee posted explain it:

i didnt think that there would be a problem with that as the higher voltage flows to the lower one, and it will always flow like that unless there is a diode or something else to restrict the current to flowing from 5v to any other lower voltage, it doesn't matter whether the lower voltage is 0v or any other number below 12v, the current will still flow from +ve to -ve.
