Just like in the second picture, where all water cooling is in the bottom and middle part of the case, making the parallel loop a clear winner for aesthetics and tube routing. A parallel loop can be done much cleaner if you have all liquid cooling components in one area of the case.

The main reason for going either parallel or serial is the overall aesthetics. Eventually, it roughly evens out when you take all cooled components into account. When going serial, the first block might get insignificantly more cooling power than the next one in line, while in a parallel connection, they both get slightly less cooling due to the split flow.

ConclusionĪfter clarifying it like that, the overall temperature differences between serial and parallel loops are quite minuscule. Just make sure to respect inlet and outlet on the CPU block, which is more important than on the GPU block. As you can see on the picture above, you’ll be utilizing all four ports thus requiring four new fittings. If you’re using, for example, an EK-Kit Classic RGB and you bought a GPU water block planning to run a parallel loop, you’d need to purchase 4 additional fittings instead of regular 2 per component. Luckily, all EK CPU and GPU blocks are designed for optimal flow restriction, so you don’t have to worry about that. So what decides how much flow each of the blocks get? Easy! The less restrictive block gets more flow. The reason why the liquid splits is that it’s looking for the path of lowest resistance. After that, the coolant continues its path to the pump-reservoir combo inlet. The first part of the flow goes through the CPU block and just passes through the GPU terminal, joining with the second flow. One part of the flow goes into the CPU block and the other circles through the GPU block. The flow looks strange, right? So, let’s break it down! The coolant comes from the radiator and enters the GPU block, but then it splits. Here, we’re going to make it a bit more understandable and easier to comprehend. A lot of people would look at the photo below and say the coolant is just going to skip the GPU. The parallel connection is not as straightforward, which is why a lot of new builders do not exactly understand how it works. This way, the coolant flows simultaneously through both radiators. This can be easily achieved with the newly released EK-Torque Angled T rotary fittings. Interestingly, the same build features a parallel flow setup on the radiators that are seen in the back.

The full flow is first received by the CPU block, and then the GPU block.

So, a single inlet and outlet are used, the coolant goes in, circles through the GPU block and takes the heat away, after which it leaves the block through an outlet. Here, we can see that the liquid flows into the CPU water block inlet and goes from the outlet into the left side inlet of the GPU block, after which it leaves through the outlet port on the right-hand side. The serial configuration is the most common one, especially on first-time builder’s custom loops, due to a more straightforward way the liquid flows. The parallel connection utilizes all four ports on the GPU block, and in this blog, you’ll find out how that works and what are the benefits and drawbacks to both configurations. The most common and usually featured is a serial connection, which uses one inlet to the GPU block and one outlet. In this article, we’ll look at the two most common ways you can configure your liquid cooling loop and we will be focusing mostly on the GPU block.
