Laing DDC-Pump 10W or 18W

RoEy · 3 Jun 2013 at 12:54

Hi all,

Had the 18W version for 3 years and it died yesterday after having just redone my PC, gutted. Looking to either get the same pump again or the 10W version. Only thing I could hear in my system was the pump so I'm really keen to fix that this time round. I'll be using the XSPC res top on it like last time.

In my loop is a feser quad radiator, Heatkiller Rev 3 cpu block for i7 920 and a heatkiller 7970 ni bi block. Would I notice much of a difference in temps if I decide to go for the 10W version? If it would be a big change then I'll stick with the 18W again but really keen to get my PC completely silent and I'm thinking the 10W would do that for me.

Any advice would be great as I'm looking to purchase one or the other today.

Thanks,

RoEy

Get the 10w and mod it to 18w

Properly decoupled 18W ddc can be made near silent.I had it suspended with tubing(hanging from the inlet and outlet - not touching the case).

Hanging by tubing I have also found to be the best way to remove the vibrations.
They also do eventually seem get noisier with age. My 10w ddc has been going almost 5 years now and for a good few years has made a distinctive buzz compared to when it was new.

Ok, I'm not really keen on completely decoupling it though. On some foam, which comes with the pump, seems to be fine overall. Main thing I'm concerned about with the 10W is temps going up. They may not as I have a relatively small loop but just not sure.

What temps do you get on your msi card eddy?

Seriously, Google it. Really quick simple solder job.

Yes I've heard about it before but haven't really got the time. I'm just keen to know how much of an impact the 10w will have on temps compared to the 18w.

I completely agree here. My 10w swiftech pump is doing the same buzzing sound and vibrates quite abit in my case. Without a spongey surface for it to absorb the vibrations it would clatter my cade apart lol.

I too would love to suspend the pump in midair but its just finding the space

It's on a mcw60 vga block and requires a copper shim for die contact (also 2700k in loop) on a single 280 rad.

During bf3, at 1.1v 1150 core, ~54c. Just for the hell of it I gave a quick blast on Kombuster for 2 mins same volts/core hits 58c.
Idle 0.9v/300c, 35c.

Not the greatest fans, so getting heat out the loop is my issue but the idle temps may be indicative, just can't be too sure on the extent of influence of the copper shim.
If your loop isnt too restrictive it ought not to be a significant effect.

The buzz is annoying, although I think I have become spoilt by PC silence. I have often considered switching to a D5 as all reports say they are extremely quiet at low settings.

Any better res tops than the XSPC Acrylic Tank Reservoir? Think I'll order the 18w version again cause I just know I'll be gutted if temps go up with 10w.

what are your VRM temps in gpuz when in bf3/kombustor?

Swiftech make a PWM version of the DDC but sadly OcUK don't stock Swiftech anymore. Its great for loops that don't currently need the full whack of the 18w but want to keep the power in reserve for future upgrades.

MCP35X
Warranty void if you remove the top though.

True, however the standard top is a high flow one with G1/4 ports so no real need to change it from a performance POV, if your concerned with aesthetics there's a white version

From memory both in the 80's at 1.1v/1150c in bf3, side 230mm would have been at low speed and I have additional sinks on the cooling plate.

99&92 in kombuster at the 2 min mark but it was still climbing and I had my side 230mm set to max. 1.2v/1200c/1600mem in unigine would see me over 100 pretty quickly.

I was shocked - and then i realised its just a gpu block - not fullcover

Haha yeah. Fullcover would be nice for the temps but the vga block has proved itself v versatile over the years.
Annoyingly in this case the 230mm fans dead zone covers the 1st pci-e slot just right.

Would something like this res work well on the motherboard tray and have a d5 or DDC hanging in the bottom compartment via tubing?

Does anyone know if the xspc res top as been discontinued as I can't seem to find any anywhere? Any other loop suggestions would be much appreciated. Will probably go with same setup as last time but may as well see if I can change and improve it this time round. Will hopefully order bits tomorrow.
