Another dead DDC 3.25 ?

[BeepBeep2]

Yeah......frightened to even consider spending money on a 'possible' failing/dead, Laing/Swiftech pump.

The EK DCP 4.0/OCZ Hydro 800/CPX-Pro is slightly worse in flow than a DDC 3.2...

That said, I got my OCZ HydroPulse 800 for $50 and it's been quiet, awsome the last month and a half.

It means I had to remove the 4 screws from the bottom of the XSPC dual DDC reservoir in order to take the DDC 3.25 for examination (after it was clear it was not working correctly). When I did, obviously a little bit of water leaked out as well (take a look at the XSPC reservoirs at their site if you dont know what I am talking about)

I took it to the evaporation chamber simply to remove all water drops or vapor and to know that if there was a problem, it was not because of any moisture.

I might add again that the engineering geniuses who built this POS left four small holes for water to leak into from the top if it seeps past the o-ring.....brilliant. Perhaps they used to design o-ring seals for the booster rockets on the space shuttle before they acquired their present job.

+1 on this. CPX-Pro on a Supreme HF (P1 plate) with very good temperature results, and no problems. If I find a better way to insulate the bottom of the pump from the case (vibration wise) it might be very good, since 90% of the sound it makes is the vibration - when I pick it up in the air, it's totally inaudible.

Since you've stated this twice...by your definition a typical CPU block or fittings are flawed designs as well. If an o-ring fails on said block, water will leak into the CPU socket, and destroy everything that was once known as a computer...

... no, but you dont put the heat exhaust holes (or perhaps they are little tiny holes for elves to climb in at night to power the f#cker with when it fails) directly beside the only o-ring in the pump and directly above where water will leak down to the pump electronics.


I dare say, my Core I7s or some of the ASUS boards I have used, can take the water and keep on running without shorting much more reliably than this DDC 3.25 joke.

Martinm - Question for ya; when the restriction is becomes high ( as some allude to here with the XSPC tops), normally the heat builds at the restriction and flows back to the pump, until the pump itself heats up. It seems like this DDC is not built to withstand 90 deg C or higher. Do you know what the one hour time to kill temp is (roughly) for these DDC 3.2s or 3.25s ?

Also, I have checked the PCB and no burned or (seemingly) damaged components. Do you know where I can get the full PCB circuit diagram ? ... I will trace it out and test for voltage/current tomorrow.
