XS, DT Waterblocks has a new waterblock. I'll post in this thread some pictures and performance data.
You will notice that it is very similar to the 5Noz waterblock, it is really just a further refinement of that concept. This waterblock started life as a nozzle improvement study on the 5Noz, the end result was a completely new block. I have also made many changes to reduce the cost and improve the function.
You will notice that the waterblock top is one piece acetal, this reduces the cost quite a bit compared to two pieces with 5Noz. Massive port spacing, expect no fitting problems. Thumbnuts are expensive enough that I can just build them myself. These nuts have a 12mm hex, you can spin them with a nutdriver if you want, but they are quite easy to spin with fingers. The internal M4 thread in the thumbnuts bottoms out on the top of the mobo mounting screws when the springs are properly compressed, this feature controls the block mounting pressure.
The nozzle, this is the heart of this waterblock design and there was a heavy development effort to choose this nozzle geometry. The bow of the base is machined into the base contact face of the nozzle, so there are visible rings on those surfaces. You can also see a few features of the nozzle and top that poke-yoke these parts so that they can only be assembled the correct way.
The base, this uses thinner stock and requires much less machining than 5Noz. The fins and micro-channels are similar to those on 5Noz. These geometries were re-evaluated through testing, but I arrived at almost the exact same answer.
Mounted on a mobo, the thumbnuts almost cover the springs completely, there is a little gap so you can see the springs are not fully compressed as you install the block. Don't look at the mobo model
