The validity of Cooler Master's patents will be the crux of this case. With the US patent system having switched from a thorough investigation of patent validity before granting, to a cursory investigation before granting and letting the courts decide if patents are valid when a conflict arises (due to the fact that the patent office was running some 600,000 patents behind at the time the switch was made, with a drastic rise in that number expected if they kept doing patents the old way). So while Cooler Master might have been granted these patents, if the judge in the case decides that those patents don't meet the three criteria for patentability: The invention must be new. The invention must be useful. The invention must be non-obvious. Especially the last one can be tricky: Is placing the pump in the radiator non-obvious when the previous AIO patent placed it in the heatsink? Of course SilverStone, Enermax and Apaltek could decide to settle before these patents are ever put to the test before a judge, if they think that would be cheaper than going through the courts.

I wonder how long Asetek's patent is valid anymore? AIO systems with the pump in the traditional place have been available for quite a while already. I reckon the patent will expire very soon, if it hasn't already.

They'll probably sue for infringement for the period that the patent was still active.

The patents system needs an overhaul because the current one is a giant mess...

They are a bit limited, put the pump on the block or put it on the rad, anywhere else and its not really an AIO. My first foray into mainstream WCing was a Swiftek kit.

BeQuiet!'s Pure Loop 2 has the pump in the waterhoses between block and radiator, so there is that option. But apart from that, yes nothing much can be done about pump placement. The only other option would be a passive waterloop, which I think DerBauer once tried to build, but I haven't seen anything about that one lately. https://www.bequiet.com/admin/ImageServer.php?ID=16deba43972@be-quiet.net&omitPreview=true&.jpg

Never seen that before, it sort of negates why somebody might go for an AIO (other than the assembly)

Seems that Wieland has created a thermosyphon based pump-less AIO prototype, which would eliminate the pump completely. The prototype is not yet at the same level as an AIO, but since it looks like a proof of concept device, which was just created to prove the principle and hasn't been optimized for performance, there might be significant room for improvement. DerBauer has posted his "review" video about the device and it seems like a promising concept to move forward with. [youtube=2S2BZlHChug]

With anything in engineering, there is always a compromise to be made somewhere, you can't get something for nothing. This seem to nail it in the noise department but at the cost of cooling efficiency, that good or bad depending on its use.

Since this is not an optimized final product, I would wait and see what they can achieve if they at least do the things DerBauer suggests in his video: make the block's contact plate copper i.s.o aluminium and close the gaps between fans and radiator for more efficient airflow through the radiator. The current proof of concept version seems less than optimal in the airflow department, something that might cause significant cooling capacity.

They can nip and tuck but i suspect that may squeeze a couple of degree's C at best.
