At the temperatures most PC water-cooling systems operate, pressure changes caused by the expansion and contraction of the water volume will be negligible. Picture a bottle of water. If you want parallel loops, you should make sure each loop has it's own pump. Which is why you often see serial loops in a lot of standard water loops. The advantage of parallel: both devices get cold water disadvantage: The higher path will still get flow, but maybe not what you think, and without seperate pumps, the only way you can control flow in the loops is to throttle down on the lower resistance part to try … The path of the water … Parallel circuits. DDC and D5 pumps can achieve 1 gpm of flow through most standard loops, such as a CPU, GPU and two radiators. Unfortunately this means the real gains of parallel don’t happen until you get beyond the useful restriction range of water cooling loops. You poke a hole in the bottom of it, water starts leaking out. Parallel thermoelectric water-cooling loop Here I consider the possibility of a relatively simple and inexpensive addition to a regular PC water cooling loop. A common misconception is that running parallel paths in the same loop is always better. When you run two pumps in parallel, the curves somewhat get stacked in the X or flow rate direction with an averaging of pressure. "The configuration you use depends on your individual cooling system. A less well-known fact however, is that the internal water volume will decrease over time, even in systems with no obvious leaks. Path of least resistance will see more flow. Re:Water Cooling: Series vs Parallel Loops 2013/05/13 15:57:01 I have my loop running a parallel bridge for the GPU's Working great! Multiple pumps work together to pump the liquid so I think running one lower than the other would just mean that one is doing more work. EK actually stated it was a better flow rate, for whatever that is worth. On a very high restriction loop you … Of course there are some other methods like passive cooling or mineral oil, but those are in really small portion. It’s only when you get to more complex loops like SLI and … higher water flow through each device so better cooling for the first device disadvantage: seccond device in the loop doesn't get cooled well because it gets already hot water from first. Parallel cooling channels are drilled straight through from a supply manifold to a collection manifold. If you want to do this worry free, I'd say just buy two of the same pump like two Swiftech PWM MCP-655's and control them at the same time with a Y-splitter on a dual pump top from … Due to the flow characteristics of the parallel design, the flow rate along each of the cooling channels may be different, depending on the flow resistance of each individual cooling channel. Now poke a second hole - water comes out of both holes. Chilled water schematic and condenser water schematic, how to read and understand the engineering drawings with real world examples, Illustrations, animations and video tutorial. Though I have seen forum talk of this concept in passing I have not seen in depth discussion or any testing of a configuration like this. At 1 gpm it takes 250 watts of heat to raise the water in your loop 1C. Water vapor can pass thru the walls … Experimentation is usually suggested. Custom Loop Water Cooling PC: In general, there are three methods to cool your PC: air, AIO (all-in-one water cooling), and custom loop water cooling. Covering chillers, pump sets, AHUs, risers, primary and secondary systems, cooling towers and bypass lines. That's essentially how a parallel loop works.
