Between 6 fans and a GPU fan, you think you'd hear the pump over them? 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. We recommend ordering the suitable top … This might actually be the issue since I sometimes hear an air bubble here or there flow through the system. 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 If you install a pump without connector, make sure to observe the correct polarity. If you install a pump without connector, make sure to observe the correct polarity. No the cheapest DDC. 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 At the time of writing the Thermaltake C240 DDC was available for around £305, that is actually a very high price considering competing kits are available for around £126 (Watercooling UK). DDC pumps ARE noisy. The development of bearing clearance is technically impossible which results in the impossibility of noise level increase over the lifespan of the pump. I didnt have any issues with overheating or the pump running hot so far. Would you guys happen to know what DDC is on the Bitspower S1 pump? Press question mark to learn the rest of the keyboard shortcuts, https://www.youtube.com/watch?v=JjalpxbtNck. PrimoChill is a PC hardware company focused on the continual development and evolution of the watercooling industry. 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. Generally D5 pumps are much quieter vs the DDC; so if yours is making that much noise check to make sure it's not sitting directly on the floor of your chassis, if it … Not because I'm an expert but because I have a keyboard.​. This product uses a high-performance Xylem DDC PWM pump. $1.59 Alphacool Decoupling Kit for Eheim/Hydor 4. This pump can be used with an adapter cable with 7V or 9V. Owners of Cooler Master COSMOS C700M cases, Bitspower has you covered for your water reservoir and pump needs with the Bitspower Touchaqua Sedna C700M. Yeah I've tried running it vertically for 1 hour or so and the noise is sadly still there. Model DC - 3.1 TPMP pump is equipped with a connector for the power supply. Come join the discussion about computing, builds, collections, displays, models, styles, scales, specifications, reviews, accessories, classifieds, and more! They're low profile design, large number of variants and excessive number of aftermarket parts and accessories make this pump a must have in any build. Quote:I'm gonna throw in my 2 cents. 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 My S1 Pump seems to be nearly silent when running at about 50% for CPU only loop. But you shouldn't have to run it at 100%. But you guys are right, put that puppy at 4500 rpm and it's the loudest part of the system. How the DDC Pump Works: The permanent magnet rotor/impeller unit is driven by the magnetic field generated by the surrounding stator. Installation and instruction manual Laing DDC pumps www.laing.de Electrical connection − The DDC pump runs on 1 Volt DC. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. The pump is an DDC 3.2 PWM. Initially my understanding was all Laing DDC pumps are the same outside of the enclosure, so I ordered the cheapest PWM version I could find - Alphacool Laing 12V DDC-1T Plus PWM. pump housing. 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 Streaming-optimized pump chambers: The pump adapter for D5 and DDC pumps comes with a streaming optimized pump chamber. Add to cart. In case of diaphragm breakage, immediately separate the pump from the power supply! 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. The flow rate … However now I'm not so sure I got it right. Proceed as described in section This is very subjective and the reason why many arguments about which is quieter. Its certainly quieter and cooler running. D5 are still able to maintain a decent flow rate where as DDC type pumps tend to drop off like a cliff. The DDC pump runs on 12 Volt DC. The stator is wrapped entirely around the rotor. I'm used to D5 pumps and I will try to find the perfect fan speed/pump speed for the best performance/noise level. Installation and instruction manual Laing DDC pumps www.laing.de Electrical connection − The DDC pump runs on 1 Volt DC. Dismantle the dosing head without connecting the pump to the power supply and make sure no dosing liquid has entered the pump housing. I think it'll last longer than the DDC pumps ive had. The bearing is selfrealigning. haha After filling my loops and running a test, one of my EK D5 pumps is making a lot of noise compared to the other loop. Here's a video of the noise where I play around with the PWM: https://www.youtube.com/watch?v=JjalpxbtNck (turn up the volume, recordings from my phone are super quiet). This is one of the latest revisions of the popular Laing DDC series pumps, the Koolance PMP-400 (DDC3.25). For a better experience, please enable JavaScript in your browser before proceeding. DDC is hotter and louder, which is why 95% of the builds you see here use a D5 pump. JavaScript is disabled.
