the reason why i'll never buy reference

There certainly might be one.  This is part of my complaint about those Manila tags.

I don't think their is a barrier.There can be a large opening letting air through and out the heatsinks.

It will make a difference but the air will still get trapped due to the amounts of air that has to go through that tiny vent.

 

That's not hydrodynamics, it's Aerodynamics,

The PC isn't submerged in water,right?...

Re pieces of paper

It was an example.  You may be right.  You may not.  That’s the point.

 

Re hydrodynamics

Aerodynamics IS hydrodynamics.  Air is a fluid for purposes of mathematics.  So is automobile traffic believe it or not.  There’s actually a system on the minneapolis freeway that got installed in the 1960’s based on this.  There was a right wing radio DJ in town named joe “Su chu ray” (I don’t know how it’s spelled) who went on for years about how stupid it was for just this reason.  They finally did tests some years ago because he was developing a following on the subject.  Cost a couple million dollars and took a week or two.  Turns out math is still a thing. They did manage to tweak and optimize it a bit but changes were near zero.

The mass and density of water creates significant resistance to a movement of a fan,as a result the fan must work harder in order to move the same volume it did with air.

So a switch from mass and density to volume.  How much mass does it move?  Would you prefer the word “fluid dynamics”?  One could say aerodynamics and hydrodynamics and automobile traffic are all fluid dynamics.  Or I could call everything aerodynamics including how water sprinklers work, or I could call it all automobile traffic systems.  They’re all the same math.

What matters is the volume it moves,you want as much air as possible to go through.

You want to cool the thing.  So what matters is the amount of heat that can be absorbed.  But you’re the one that switched measurement systems mid jump.   It doesn’t disprove the point.

Air just moves the heat away,it can't "absorb" like water due to the difference in thermal conductivity between the two.

It cant absorb as well.  There’s a coefficient one uses.  I can’t remember what it’s called.  I vaguely recall water being the base so distilled water is 1.0. Theres pressure too though.  Ambient air is something like ~15 psi and it’s got a certain amount of water vapor in it that also changes.  Makes stuff complicated.  They’re very different for water and air.  This usually means one need a whole bunch more air to do the same job.  In the end it is still the same job though.  It does absorb “like” it though.

Thats quite a bold statement though.

 

I am not saying that you are wrong, there may very well be a case where this will occur but there is just too many factors to consider.

 

The type of case you use, the fan configuration in the case you have, the CPU cooler may play a huge impact as well (something like Ryzen Wraith cooler will affect the airflow in that area quite a bit differently than a tower cooler like Noctua NH D-14 for example), heck even picking a lower PCIe slot position for the card will make a difference...

 

You could make a statement about making hot air "pockets" in the case about almost anything because it really comes down to way too many factors.

Depending on wattage, this looks to more function over form given the extra fins for surface area. At the end of the day, it's in the case and out of sight. Meh 

 

IMHO, it should all be fins and fan. I could care less about the aesthetics.

That's basically thermal conductivity.

 

Air thermal conductivity: 0.024 W/m K

Water thermal conductivity: 0.6145 W/m K

 

It's a huge difference...

FYI, air (gas) becomes fluid at high speed. In fact, fluid dynamics applies to gas flow in general. Just ask GE, they design turbines.

My point is that hydrodynamics and aerodynamics are fluid dynamics,but hydrodynamics is not aerodynamics.

Ironically this is the exact same reason I always at least consider reference.  I take your point though.

Semanitcs.  The math is identical.  You’re not wrong though.  This gets into whether penguins fly.  I think they do.  Just not in air.

Fantastic! Had this video been available prior, I would have voted differently on the design ;)

I think that NVIDIA uses different vent design on the IO shield,other than that it looks fairly accurate.

Good Job 😀

Yeah, I should have included at least one USB type C, or maybe 2, I can still change it, but now it too late to catch the hype train.

Stacking multiple RTX 3080 prototypes, the air will pass through. This system will allow the air passing through one GPU to other. This Is a special feature and also fan blades are surrounded by a turbo ring winglet.

My sensation is that  the system is a push from one side and pull from the other side because the camber airfoil profile of the blade looks reversed.

 

It looks to me that can be a pull extractor and not an intake. In any case air will pass through one GPU to other

If not the blade will spin in opposite direction.
