Gonna buy a new pump for my setup over the weekend. I currently have a Laing D4 which i find very noisy but performs very well. My Loop consists of a CPU, GPU block and a single rad. I was thinking of getting a Laing DDC-1T Pro, Laing DDC-1 Ultra or the laing D5. So a couple of questions. 1) What’s the difference between the Laing DDC-1T Pro and Laing DDC-1 Ultra 2) Is there a performance difference between the D4 and D5 3) Will there be a performance hit if i get a Laing DDC-1T over my current pump 4) Which one of the pumps is queitest Many thanks
Get a sunbeam rheobuss and hook the d4 to it. Slow it down to where you feel comfortable with the noise. It wont effect performance much.
Laing DDC-1T Pro This product is the new revision. This pump is the first one of the World which is being brought into action in serial produced watercooled workstations and is ideal for the watercooling of processors and elektronical components. Furthermore it has multiple applications due, due to its size and performance. This DC pump is an electronical commuted ball engine pump with running periods of notedly more than 50.000 hours at 12 volt. The only moving part of a ball enginge pump is a spherical formed rotor-/ running wheel unit which bases itself on an ultra hard wear-resistant ceramic bearing ball. A conventional shaft with shaft bearings and shaft seals does not exist. The spherical bedding of the rotor-/ running wheel unit on the ceramic bearing ball offers many advantages: neither bearing clearance nor increase of noise is possible - due to this principle. So the pump stays at a low noise level during the whole running period. The bearing is self-adjusting and is lubricated directly from the pumping medium (wet running pump). This makes maintenances unnecessary. As the rotor always is magnetically held in the provided position, tiny soil particles are no problem. Normally a blockage of the pump is not possible. Also after longer standstill the pump starts confidently. The permanently magnetical rotor-/ running wheel unit is being moved by a magnetic force which is produced by the stator around. This stator is completely mounted around the rotor. Thus, the pump with its 38 mm is just a little higher than the stator itself and fits into all standard PC-, barebone- and mini-PC cases without any problem. Usually, a separate magnetical shielding is not necessary. The ball enginge principle offers an economical use with comparatively high performances. Due to voltage variation, the DCC direct current pump can be regulated very simply and at large performance range. All media contacting parts are completely corrosion resistant. Technical data: Measures: (w x d x h) 62x62x38mm (without connections) Kind of engine: electronical commuted ball engine Nominal voltage: 12 V DC direct voltage Allowed voltage range: 6 to 13.2 volt Lifting height at 12V: 3.7m Max. lifting height: 420L/h Transport media: water, water-/glycols-composites* Max. system temperature: 60ø C Media contacting parts: stainless steel 1.4571, PPS-GF40, EPDM O-rings, aluminium oxide, hard coal Connections: 2 x G1/4" hose connections Laing DDC-1 Ultra This product has gone under new revision, with more power output. This pump is the first pump worldwide, which can be installed in mass-produced water-cooled workstations, and it is ideally suitable for the water cooling of processors and electronic components. Due to its size and output, a multitude of applications are available. This pump is an electronically commuted ball-motor pump, with running times of more than 50.000 hours at 12 V. The only flexible part of a ball-motor pump is a sphere-formed rotor-/runner unit, which is propped up against an extremely hard, wear-resistant ceramics bearing ball. A conventional axle with journal bearing and shaft sealing is not available. The spherical bearing of the rotor-/runner unit on the ceramics bearing ball provides a lot of advantages: a development of the bearing play – and thus a noise increase - is theoretically not possible. The pump is silent over the whole running time. The bearing is self-adjusting. It is lubricated directly by the delivery medium (wet-running pump). There is basically no need for maintenance. Since the rotor is always held magnetically in the intended position, smaller dirt particles are no problem. Blocking of the pump is not possible under normal conditions. Even after lengthy downtimes a safe approach is given. The permanent magnetic rotor/ runner unit is propelled by a magnetic field, which is produced by the surrounding stator. This is built entirely around the rotor. The entire pump is thus with 38 mm only a little higher than the stator itself. It easily fits into all conventional PC, Barebone and Mini PC cases. A separate magnetic shielding is not necessary under normal conditions. Normally, a separate magnetic shielding is not necessary. The ball motor principle enables an economical enterprise with comparatively high achievements. The tension variation can easily regulate the DDC direct current pump over a large capacity range. All medium-affecting parts are completely corrosion resistant. Technical data: Dimensions: (WxLxH) 62x62x38mm (without connections) Motor construction type: electronically commuted ball-motor Working voltage: 12 V DC Voltage Admissible voltage area: 6 to 13,2 V Delivery height: at 12V: 4,7m Max. delivery rate: 600L/h Delivery media: water, water-/glycol compounds Max. system temperature: 60° C Medium-affecting parts: stainless steel 1.4571, PPS-GF40, EPDM O-sealing rings, alumina, hard carbon Connections: 2x 1/4" hose connection Characteristics: Plexi cover, 5mm LED drilling, incl. uncoupling set for 3,5” slots. The second one will be the one im going for as its quiet and powerfull.
MUCH Higher head pressure which is what counts the most in watercooling systems. The above show pump performance with NO restrictions imposed - ie: not fitted in a loop. Now, take the same pumps and plumb them into a watercooling loop and look at the new measured results... The extra head pressure of the DDC with modded top allows it to overcome the restrictions imposed by the loop and thus results in a higher final flowrate.
