LYNK+ Demos AMD Radeon RX 7900 XTX GPU With Modular Water

German water-cooling manufacturer, LYNK+, has unveiled a new modular

German water-cooling manufacturer, LYNK+, has unveiled a new modular water-cooling concept and demoed it on AMD's Radeon RX 7900 XTX GPU.

LYNK+ showed off two demo units of its new water-cooling concept design for GPUs which were given a closer look by Der8auer. The two demo units included an NVIDIA GeForce RTX 3080 FE & AMD Radeon RX 7900 XTX MBA designs. Both GPUs were equipped with the new cooling solution which features a modular design.

Starting with the GPU block, the main heatsink that sits on top of the GPU is made out of a die-cast aluminum body and the GPU area is CNC-milled and features micro-channel fins that will allow the liquid to cool it efficiently. The whole unit is designed to cool the GPU, memory dies and the VRMs but since this is an aluminum block, it will be hard to see where the water is being channeled since it doesn't has the acrylic window that you see on off-the-shelf water blocks available today. Another major difference is that the water block doesn't house the pump in the block itself but rather within the radiator block.

The radiator is interesting and two designs were showcased, a 240mm and a 360mm. Both feature the pump, reservoir, and radiator along with additional air pockets so that air cannot get trapped in the water block since it can cause adverse effects in relation to the temperatures. But what makes the LYNK+ modular is its connectors which come in a sort of quick connector design.

These modular connectors can be attached to the water block by simply plugging them in. The demo version was using a screw to hold the tubing firmly in place. There will be a better unlatch mechanism introduced in the final version but having a modular design allows you to unplug the radiator without having to take out the GPU first or causing spillage in such a case. The design also allows users to use a secondary LYNK+ loop for added cooling performance.

The demo unit running the AMD Radeon RX 7900 XTX graphics card used a 360mm Radiator and was running under 50C with GPU Junction temps close to 75C while being stressed in Furmark. It looks superb for a concept design and we can expect further refinements in final designs.

While GPU AIO cooling is nothing new, why LYNK+ modular water-cooling makes sense because after you buy an existing AIO GPU, you'd have to throw away the GPU and the entire cooler when upgrading to the new one since you can't unplug the cooling, and attach it to the new one as they are designed differently. With LYNK+, you only need to detach the GPU and the water block & you can use the same reservoir, pump, and radiator with a new GPU. All you need is to make sure that LYNK+ has the proper aluminum water block made for your GPU. This is still a concept design right now but it is definitely an interesting one and we can't wait to see manufacturers adopt it in their future GPU designs.
