It is no surprise that heatsinks and water cooling gear sometimes is advertised with claims that stretch plausibility. For instance I have had a few things to say about Thermaltake's C/W values in the past.
Anyway, the worst example of this I have seen in a while was brought to my attention today:
http://www.sharkacomputers.com/neinxlowprhi1.html
"The X-Flow achieves maximum performance due to a new and revolutionary flow guidance design within the interior of its compact dimensions. A unique turbulence principle makes optimal utilization of the cooling agent possible without cross-section contraction.
Therefore, this water block does not create any back pressure nor stress the water pump.
The crosswise arranged current profile inside X-Flow produces such an enormous amount of turbulence that the radiator can be preseverd from overworking to keep the cooling agent cool.
This special interior design, which operates without any moving parts, uses the thermal capacity of the cooling agent optimally and makes extreme cooling possible. In additon, the flow area is not restricted and the flow of the cooling agent is not obstructed or slowed."
Allow me to paraphrase:
"This revolutionary product is tied to neither the laws of physics nor heat transfer. It's magic!"
Are there NO laws governing such? I have a flowmeter and a method to measure dP. I am tempted to purchase this block and then take these clowns to court if flow rate loss or pressure drop is observed.
I also do not know what to make about the comment regarding turbulence and low water temps at the radiator. Something lost in the translation?
I am sure this isn't isolated, and I am also sure that this is just the tip of the iceberg. Just as C/W values of dubious value began being used as marketing after o/cers started publishing them, now it looks like important parameters for wcing are soon to be abused and misused to hawk wares.
