This Cooler Makes No Sense - Fluix Tri-Swift

I've dealt with water so much I've been up to my neck in it. And with that kind of experience I can tell you that the first hole is positive (out), and the second is negative (in). This means the third hole is obviously your ground hole. It's basic waternomics.

I guess splitting the flow to two same-sized tubes halves the speed of the flow. Using tubes with smaller diameters might actually increase the performance.

[@priitmolder6475]

Only way I would see this twin port make sense: instead of straight fins, they would be wavy. Tho the wave amplitude (lack of a better term) should be rather small to avoid Tesla valve effect.

[@robotiod]

Yeah with the split design the water coming into the block is at a trickle compared to just 1 intake. Your idea would work conserving the pressure of the water but I think at best you would only match the performance of a traditional block. It's not like the surface area is increased in any way by coming in from 2 directions. The water will only be in the block half the time compared to a traditional block.

[@lifeisgood12341]

Im not sure that matters since it will be cut down to the final diameter in the block.

[@teardowndan5364]

Water blocks with a single intake or outlet in the middle using a mid-plate to channel the flow down the center of the micro-fins stack are splitting flow within the water block, either via fin-less channels along the edges or galleries in the cover.

Most instances that use such a concept in larger scale is done with two pumps. This is to reduce the size of each pump compared to one big one. In this instance, using two lines doesn't change the flow rate of the system, and the only benefit may be directing the coldest flow to certain parts of the die. But that won't necessarily be consistent.

[@zazethe6553]

No, a pump and its motor only need to be a little bigger in size for double the flow. But two pumps are at least twice the space. A single tube is also always better than 2. Surface area of a circle, or cross section of a tube, is pi * radius squared. Doubling a pipe in diameter gives 4 times the flow in water volume for any pipe, increasing it by half does slightly more than double the water volume. So a 1.5inch pipe has a bigger water volume flow than two 1 inch pipes. Two tubes have an additional problem, it increases the the total tube wall surface area, this increases the fluid resistance of the tube, so its less efficient than just 1 slightly bigger tube. A circle has the smallest circumference for its surface, it is the most optimal shape, so its way more efficient to run a single slightly bigger tube. There is zero instances were this makes sense, only maybe for redundancy in case of failure, certainly not for efficiency.

[@tervalas]

@@zazethe6553 I didn't claim anything about 'doubling flow'. "Centrifugal pumps in parallel are used to overcome larger volume flows than one pump can handle alone." And yes, I've worked with plenty of pumps that were quite a bit smaller than they would have been if the application used one. Yes, increasing the tube size is the better thing to do for flow (I even mention that in this case the setup is poor because the outlet tube is the same size), but there are tradeoffs. Too big and you'll runout the pump (which can damage it). Too small and you'll make the pump do a ton more work (which can also damage it). I completely agree that the losses in two tubes can slow down flow, but compared to the flow gain you get from using two pumps it can become negligible. The old adage is 'Pumps in parallel for increasing flow. Pumps in series for increasing pressure'.

My thought would be, if we are going to use two inputs and one output from a water block then we should have two radiators one for each inlet into the water block.. and just split off the output into the two radiators.. kind of like a double loop.. I would say it would increase the cooling by doubling the water time volume in the radiator as well as doubling the radiator cooling, having two radiators.. the return hose would dump into the reservoir and then be pushed into two separate hoses one to each radiator.. or you could have two reservoirs and two pumps splitting the output from the water block prior to sending each to a reservoir.. I think it would help with cooling.. and the water block with the two inlets should each cover half of the water block itself..

The problem with the 2 pump theory is the single outlet.

Furthermore this solution will increase cost and loop complexity.

Thank you for mentioning the God that is 'Cathar'. I still remember his madness making a pure silver version of the water block - Yes, Silver the metal.

[@Muscleduck]

I had a DangerDen block thst did this in 2007, for my 4400+. I actually still have some DD blocks. Loved their stuff.

[@Techie_Justin]

I just thought of this a few days ago. I been watching LTT for so long I learned a good bit of the metric system.

[@ragerancher]

It seems that water coolers have reached the limit in terms of heat transfer from the CPU to the liquid and now need to focus on trying to dump more of that heat out of the liquid at the other end.

[@keatoncampbell820]

I was under the impression the entire point of having more inlets is so you can attach two pumps directly to the CPU, which is something I'm surprised Linus didn't test. Two pumps, two radiators, might not actually help that much but that would seem to be the point.

[@AGuy-vq9qp]

Best case scenario it’s no better than having two pumps in series, worst case scenario you break one.

[@JathraDH]

Its been demonstrated that pumps in parallel is a horrible idea. It provides almost no benefit with some big drawbacks. Pumps in series provides some good benefits with minimal drawbacks.

[@keatoncampbell820]

@@JathraDH I think this is a more "edge" application. If there is barely an advantage to having them in parallel, then someone will do it. Saying they are more efficient in series simply means there will be two parallel series of pumps. They *will* make pump arrays if you tell them the truth. AFAIK the best cooling solution is just a single good pump lmao

[@JathraDH]

@@keatoncampbell820 I always run 2 pumps in series for redundancy. It has the added benefit of being able to turn them down quite low so they are silent and still get decent throughput. But yea mad lads will run 4 pumps for sure, you are right about that. The problem with parallel pumps, even if you put 4 pumps with 2 of them in series is that the fluid path splits, so if one pump stops working it causes really weird problems because the pressure is imbalanced between the two paths. The articles I have read that have experimented with it all say that its just a net loss to use parallel overall. This is really a problem with all parallel setups. Its very difficult to balance the flow rate evenly through both halves or control it to go where you want.

[@keatoncampbell820]

@@JathraDH I mean it's definitely possible. It's just ... At that point you're doing rocket engine plumbing optimization. They are a great case study, actually, as they use two series (3 stage turbopumps?), one for fuel and one for oxidizer, running in parallel into the combustion chamber. Of course that just goes to show you that series is far more effective than parallel, as if running fuel and oxidizer through the same pump was possible, they'd do it! Personally I try to size any plumbed system components, especially in computers, so that the max operating speed of the pump won't ever exceed 50%. The pump is absolutely oversized but also is going to be very reliable and last a good long time. There's no real difference between big pump and two normal pumps in series. You could also run two pumps parallel, and just not run one of them unless the other fails. That would require some clever plumbing to ensure both can operate at normal effeciency while the other is a paperweight, but it has some precedence for immediately redundant systems. I think there were a few military land vehicles that had a couple fuel pumps in the gas tank, each routed to the inlet. If one shorts to ground, the other receives power. Just food for thought

[@lexeriw]

Back in 2005-2006, there is was a guy in my town (Aitor) that build watercooling from scratch even the radiator. And it had a CPU Block model with two inlet and also the radiator had 3 conections

I remember my roommate wondering why I was ordering machined computer parts from some guy in Australia. I still have my Storm to this day.

[@lomelyo]

I feel bad for the company having their product completely destroyed with 1 video. But that's what they get for releasing a 229USD product. Keep in mind that they have 3 years warranty and a 14 day money back warranty with 20% restocking cost.

[@darthos9804]

Wow even THEY have a warranty lol

[@Matt561]

If you talk that much shit you need to back it up throw away and they just shit the bed. It's an interesting idea hopefully they can figure it out.

[@Sum_Guy]

Why does Tynan look like he's about to MacGyver this shit and then take out a whole squadron of enemy combatants using engineering.

[@Petch85]

8:30 It would be really nice if you would add the water temp here, just as you have the ambient. Then we could estimate if you are running with way too much radiator area, way too little or are reasonable amount. 🙂 Also I liked your how much have bocks improved until know vs how much do they claim.

[@Chipsaru]

There is no such thing as too much radiator area, *laughs in 13x120mm rads*

[@Petch85]

@@Chipsaru hehe... I get what you mean. But at som point there is no gains, at some point you cannot pump water through it, making it way worse. I only have 2x3x120mm, should have picked 2x3x140mm.

[@Chipsaru]

@@Petch85 radiators are low restriction, you easily add more if you are running D5 pump

[@Petch85]

@@Chipsaru I am not running a D5, but I could probably get room for two 1x140 rads. But as it is now I my delta temp between air and water is 5C thus I don't think there is no reason to, for now.

Thank god I keep seeing these guys everywhere and with the amount of ketchup and mustard cables I seen on the product I thought it was a fake company

[@heyitsjel]

Awesome video! Definitely takes me back a few decades to my introduction to water cooling....

[@Sebastian-Quintero]

My 12900k on an 360mm AIO was right around 85-88C when under load with a peak of about 91C. Swapped out the Intel Mounting Bracket for a thermalright mount and temps dropped to low 60s under load with a peak spike of 80C. Almost impossible to have proper test results without the Thermal grizzly CPU bracket or equivalent. 12th gens biggest issue is intels mounting bracket.

[@maksymiliankuznik4856]

If today's coolers are almost unable to cool a 12th gen i9, I wonder what happens when the next-gen CPUs will hit the markets.

[@bobcorn69]

Not a whole lot. Intel will fall on their stupid face and AMD will laugh their ass off.

Nothing, everything will be as usual. Vast majority of people don't buy halo products.

[@TheTimtam112]

Probably the best visual demonstration of boundary factors in a PC is the dust that settles on fans. Even if these fans are in constant use, dust will settle on the pressure-side of the fans, even if these are high flow, low pressure fans.

Exactly what I thought... Hopefully, they'll take it in stride and make better stuff but this kind of blow might just kill them out of the gate or at least put them in bad standing for a while

[@ThePjr001984]

As someone who works with hydraulics, splitting a hydraulic line reduces pressure on the line and fittings. In hydraulics pressure is caused by resistance in the line, and resistance reduces flow. The Increase in flow from splitting one hose into two is due to a reduction in resistance. Two important caveats to note here, first a reduction in resistance will also reduce friction between fluid and the hoses (which adds heat to a system) lastly the maximum flow of a system is determined by the speed of a pump.

[@eduardocarrasco8830]

Linus, laminar flow in fluids is tested by calculating the reynolds number, which in fluids different than water stands for [ (fluid density) * (internal pipe diameter) * (flow speed) ] / (dynamic viscosity). In a typical pc loop with a flow rate of 4 lt/min and using an internal diamter of 9.5 mm, you still get turbulent flow in the pipes with reynolds number around 8000. Laminar flow range is below 2300. Transition flow is between 2300 to 4000. Turbulent flow is above 4000. That's for water, for the coolants used here should be roughly the same, perhaps a bit higher as the viscosity should be a bit higher than water. In reality is very hard to generate a system that falls to laminar or transition flow, this is typically found in fluids that are non-newtoninan and/or carry solids that in the mix generate a fluid that is times more viscous than water. Which is not the case here. The main idea of loops is that the water stays as little as possible in the same place, so high flow rates are always beneficial for pc loops, this also has been tested by der8auer. But, the reason of existance of those fins and channels is to make the water stay as long as possible on the block so more heat gets transferred in the contact patch. Which is the same reason why the radiators have a long path inside, so the fluid can lose heat by passing on the cold zone for the longest time possible. So there is always a trade off between fluid flow speed and how much radiator heat power you have. Those holes in the swifttech block, probably were related to the fact that in those days the CPU had direct dies, so you benefit from having as much a different jet channels flooded with cold fluid. But in CPU's these days, you need to do the opposite as there's already a heat spreader that did part of the job. This block with 2 inlets, basically is dividing the flow in 2, meaning that at the same diameter you are lowering the flow speed by half going in, this is making it more laminar, not more turbulent. There is actually no benefit at all in doing that unless you are trying to fill the block at 2 different locations at the same time. The only thing the block needs is to have the fluid pass throughout the whole inside block prior getting out, therefore the fluid can get heat transferred. That's why the distribution plate is there. When the fluid gets out from the pipe to a bigger area as the inside block, basically you no longer have the same flow speed inside, is lower, you lose the pressure as well as the fluid needs to expand and use all available space. You are passing from a small room to a big one, so how do you fill it even ?, you use the distribution plate that jets and channels that flow all over the place in order for the copper block be able to transfer heat. Then you just finish the job by channeling the fluid out of there.

My father worked on water cooling PCs in the late 80s to late 90s (okay well servers). I mentioned I was going to do a water cooled 4 litre build. I never thought I would see someone panic as much at the thought. Even when I said I was not going to run it prior to a 24 hour pressure test with air... At least I know truly how much water cooling has matured after him serenading me with nightmare fuel for 2 hours straight. He even mentioned that they had to install a drain in the server room at one point!
