Every AIO on full speed DDC pump and even D5 produce some noise. The thicker Koolance acetal top again seems to help reduce noise levels of the DDC series pumps. I have three DDC 3.1 PWM pump/res combos (2 EK, 1 Bykski), no issues, the oldest has been going over 3 years in a system with 2 rads, CPU and GPU. 12 Watt) Voltage range: 8 to 13,2 Volt (Minimum startup Voltage 9 Volt!) While being a perfect fit within this full tower chassis, the reservoir’s PWM enabled S1 pump is dissimulated at the back in order to provide an unaltered look to your PC. 2010/05/15 20:26:17 Something else that works well is a piece of neoprene. Not bad for such a small device. Currently fans are running at 800~850rpm and all I hear is the pump noise. Regarding the noise,my EK DDC 3.2 PWM Elite edition have been quiet Reliability, my EK DDC 3.2 PWM Elite edition failed after 8 months, but running currently dual DDC pumps and they're 12 months old and no issues Hope this helps Thanks, Jura After running old style DDC pumps for at least 10+ years, I recently switched to a 3.1 which failed after less than a week, replaced it with a 3.2 which is running without issues for more than 2 months now. The CORSAIR Hydro X Series XD3 RGB Pump/Reservoir Combo features a high-performance DDC PWM pump, integrated RGB lighting and in-loop temperature sensor to … If you stick it in a heatsink housing the heat won't be an issue. This pump features 3/8" (10mm) non-removable plastic barbs to support any 10mm ID tubing and is compatible with any EK-DDC X-TOP pump top and X-RES series pump reservoir combo unit. Using an 4yo Swiftech DDC pump (not sure exact model they've got several of them) I've found that PWMing it to about 70% drops the high pitched pump noise below the noise … Consequently, the pump continues to work quietly throughout its entire service life. But you guys are right, put that puppy at 4500 rpm and it's the loudest part of the system. 5. PWM on the fans is a very big plus, missing this on the pump is a little disappointing, in fact controlling the pump speed is pretty difficult so this does mean some pump noise is unavoidable. However the new controller board has PWM and running it at 40% makes it quiet enough to at least not go deaf next to the PC. 3.7 EKWB EK-DDC 3.25 Pump; 3.8 Bitspower DDC 3.2 Pump PWM; 3.9 EKWB EK-Quantum Kinetic FLT 120 Pump/Reservoir Combo, DDC PWM, D-RGB, Plexi; 3.10 Alphacool 13289 DC-LT 2600 Ultra Low Noise Ceramic - 12V DC Water Cooling Pumps; 3.11 PrimoChill Enhanced D5 Liquid Cooling 12V Pump Motor - PWM Enabled - Single Edition − DDC-1P and DDC-1T are equipped with a connector for the power supply. Its certainly quieter and cooler running. And if not how do I fix it? AT Protect Plus or … VerticalScope Inc., 111 Peter, Suite 901, Toronto, Ontario, M5V 2H1, Canada. Installation and instruction manual Laing DDC pumps www.laing.de Electrical connection − The DDC pump runs on 1 Volt DC. Owners of LIAN LI O11 DYNAMIC cases, Bitspower has you covered for your customized reservoir and pump needs with the Touchaqua Sedna O11D. A forum community dedicated to overclocking enthusiasts and testing the limits of computing. Model DC - 3.1 TPMP pump is equipped with a connector for the power supply. This the quiet version of DDC will work best for low noise system with limited space. I wanted a decent pump without much noise. 3.7 EKWB EK-DDC 3.25 Pump; 3.8 Bitspower DDC 3.2 Pump PWM; 3.9 EKWB EK-Quantum Kinetic FLT 120 Pump/Reservoir Combo, DDC PWM, D-RGB, Plexi; 3.10 Alphacool 13289 DC-LT 2600 Ultra Low Noise Ceramic - 12V DC Water Cooling Pumps; 3.11 PrimoChill Enhanced D5 Liquid Cooling 12V Pump Motor - PWM Enabled - Single Edition DDC pumps ARE noisy. As we mentioned before, DDC pumps are one of the best out there, right alongside D5 pumps. I just got a D5 for my new loop over the DDCs ive used for years. How the DDC Pump Works: The permanent magnet rotor/impeller unit is driven by the magnetic field generated by the surrounding stator. The integrated reservoir can hold up to 180ml of liquid. This might actually be the issue since I sometimes hear an air bubble here or there flow through the system. Loosing the foam decoupler however reveals a similar erratic and harmonic variable results up to 9 dbA higher than the decoupled test. The core of the unit is the market-proven EK-DDC 3.2 PWM water pump (4-pin PWM FAN header). Yeah I've tried running it vertically for 1 hour or so and the noise is sadly still there. I didnt have any issues with overheating or the pump running hot so far. With the D5, you can go for a PWM, with your motherboard/software controlling the pump speed, or you can buy a vario and adjust it yourself (Basically, you set it to 2, then to 5 to bleed the loop, then back to 2 and leave it there forever) level 2 While being a perfect fit within this mid-size chassis,this customized reservoir's DDC-S1 pump is dissimulated at the … How the DDC Pump Works: The permanent magnet rotor/impeller unit is driven by the magnetic field generated by the surrounding stator. So here's the deal, a while ago I bought a used DDC 3.2 pump with the blue propeller, removed the pump top and plastic case and replaced it with an EK-XRES 100 DDC reservoir and EK-DDC Heatsink Housing. Everyone perceives sounds differently. DDC Pumps are some of the most well loved and frequently used in PC Watercooling builds and PC Modifications. 2nd the propeller design is taller than a normal ddc pump so it barely fit into my r220 reservoir without chocking the waterflow or grinding on the reservoir. Regarding the noise,my EK DDC 3.2 PWM Elite edition have been quiet Reliability, my EK DDC 3.2 PWM Elite edition failed after 8 months, but running currently dual DDC pumps and they're 12 months old and no issues Hope this helps Thanks, Jura You can't find completely silent pump. This unit offers increased hydraulic performance (up to 15 %) compared to original factory top. The Alphacool SilentBox is a DDC Pump mounting and noise decouping solution that offers: Silence: A completely enclosed box surrounds the pump. DDC Pumps. I've now after a long wait replaced the controller board with a repair/upgrade kit from DIYINHK and carefully reassembled the pump and reservoir by only tightening the screws until i feel a bit of resistance in the allen key. DDC pump is a direct displacement control pump utilizing an advanced slipper piston design. i meani run a PWM DDC 3.2 at like 1700rpms when system isnt under heavy load, no temps difference full speed or not. pump housing. Is the noise still there when your reservoir is vertical? If something appears too good to be true, it probably is.​. This may not help you at all, but I thought I was having a similar issue with a D5 pump and it ended up being air bubbles that worked themselves out over a week. The stator is wrapped entirely around the rotor. The stator is wrapped entirely around the rotor. Add to Cart. DazMode DDC 3.1. 1set of BPPRE-WTCR150-DDC 1pcs of Bracket 1pcs of BP-ETAIR 1pcs of BP-WTP-C06 1set of Mounting Screws/Accessories. Despite a remarkably small footprint of 2.4" square, the pump features an astounding 5,2m of head to provide superior flow rates in today's most complex liquid cooled systems. Thanks I'll try to see if it gets better after leaving it running for a longer period of time. − DDC-1P and DDC-1T are equipped with a connector for the power supply. As a result, the entire pump is only slightly taller than the rotor itself, measuring only 1.5″ in height, perfect for applications where space is limited. Not unhappy with it. Maybe you are just more sensitive to the audio frequency than to the audio frequency of the DDC pumps. The DDC pump runs on 12 Volt DC. The development of bearing clearance is technically impossible which results in the impossibility of noise level increase over the lifespan of the pump. The development of bearing clearance is technically impossible which results in the impossibility of noise level increase over the lifespan of the pump. This is very subjective and the reason why many arguments about which is quieter. The DDC spherical motor pump. Laing DDC 3.1 Quiet 10W Pump ( MCP350, DDC-T1 ) quantity.
