Jay I really appreciate these kinds of videos. I'm planning a custom loop in the next year or so and I really love to see how all the different parts work and what works best.

Yay! Another video about water-cooling!

Great video! So the conclusion is to use the type that makes the most sense for where you have to route the tubing. I think for vertical mount rads, I'd rather have the crossflow simply because it would allow for easier draining of the system with all the fluid draining out the low end by gravity.

Love to see a retro-watercooled build. I'd love to see how you guys used to do it 'back in the day'. And see how it compares to now.

Hey Jay, I wanted to help you out with your explanation of why these two radiator formats are essentially the same. Great test btw! With the same pump, setup and two well made rads the flow rate through both will be close to the same as rads typically don’t have a lot of flow restriction by design. This means that the fluid is spending the same amount of time in both rads. I hope that makes sense, basically if your output flow rate is the same for both rads and the rads are the same size then the coolant is spending the same amount of time travelling through the rad in both cases. Where there is a major difference is the speed that the coolant flows through the radiator tubes. The xflow rad will have about ½ the speed through the radiator tubes as a dual pass radiator of the same size. The theory behind this is that the slower moving fluid will have more contact time in the tubes to expel heat to the air. Now the fun part, why this doesn’t quite work and the radiators are essentially the same efficiency. When the flow slows down it loses turbulence and this loss of turbulence effects how efficiently the coolant can expel heat. Think of the coolant flow as a highway. The coolant is the cars on that highway and each car is carrying a heat packet. In the example only cars on either outside lane of the highway can get rid of their heat packets(shed heat to the copper). There are two basic types of flow possible, Laminar and Turbulent. Just like on a highway, most flow through a tube will be more laminar than turbulent(cars will mostly be moving in the same direction and most of the time cars are in a single lane). 100% laminar flow would be all of the cars staying in the same lane the whole trip. 100% turbulent flow would resemble something like the Shriners in a parade all of the cars swerving all over and looping around while they move forward. This is important when we remember our heat packets and that they can only be deposited on the outside lanes. As the flow becomes less turbulent, fewer of the cars in the inside lane make it to the outside lane to deposit their heat, so even though the cars are spending more time on the road, really only the outside lanes can expel heat efficiently. Radiator designers know this and this is why the rad tubes are very flat, this increases the number of outside lanes in proportion to inside lanes vs a round tube. There is always a flow of liquid in the center of the tube that is warmer than the liquid that is actually touching the copper. How a dual pass rad keeps up with cross flow even though it’s moving through the tubes much faster is that when the coolant hits the rear tank it is mixed up. In our example this has the effect of shuffling all of the cars between the lanes, this allows some of the cars that were in the middle flow to now efficiently dump their heat packets. Xflow keeps up with dual pass because the slower speed allows some of the inside cars to pass their heat packets to cars on the outside lane, this is less efficient than direct copper transfer though. I hope this makes sense and it’s the same outcome as you saw, just a different explanation as to why.

That makes a lot of sense, is a very good representation, and I gave you an up-vote. As the heat is transferred from the fluid to the metal, the imbalance is rectified by the heat moving from the hotter fluid (cars in the inside lanes) to the cooler fluid (cars in the outside lanes) because heat is always looking to move from hot to cold. The hotter fluid is just energy in a more active state than the cooler fluid, so it wants to move to a lower state of energy. A bowling ball on top of a ladder "wants" to move to the floor, but it can't until some klutz knocks over the ladder and then, as Murphy says, it lands on the buttered side of the toast. The imbalance of heat within the fluid will continue the process of moving toward the cooler fluid even when it's not touching the metal. If you notice those Shriners, they toss their candy even while they're in the middle of the street, transitioning from one side to the other. In my analogy, they're tossing candy to the Shriners in the outside lanes so all of the Shriners can have the same amount of candy when they get to the end of the parade route. One thing that you mentioned ("spending same amount of time") is that the pump is forcing the fluid through the loop at a consistent rate. If the pressure or flow is measured at any point in any tube, it'll be the same. When it leaves the tube and gets to the X-flow it will slow down as it makes its way through the fins because the cross-section of them is greater than the tube. When it collects at the outlet fitting, the flow increases to match that in the tube supplying the rad. In the dual-pass rad, the same thing happens, but since there are fewer fins, the flow is faster in the fins than the X-flow, but still slower than the tube. So if the flow within each rad is linear, then the math is simple: [dual-pass] 2x the speed in 1/2 as many tubes = [X-flow] 1x the speed in 1x as many tubes.

_"the slower moving fluid will have more contact time in the tubes to expel heat"_ _"Xflow keeps up with dual pass because the slower speed allows some of the inside cars to pass their heat packets to cars on the outside lane"_ That doesn't make sense to me, considering the travel time is the same in both rads.

@DanielODonnellProAwe

The dual pass (and all those quick disconnects) will put more stress on the water pump. Perhaps a negligible amount, but something. Coming from the race engine cooling world, highest flow pumps with crossflow radiators and least amount of resistance will have the greatest cooling capacity, given the same tube and fin designs.

I would love to see some methods of getting the heat out of the room tests. I used to be able to ,, or rather, 4 years ago I got fed up with the noise and heat, so I just replaced the tubing with 5 meters of tubing, and threw the radiator and pump out the window. Now,, I do have a balcony located right there, so the stuff landed on a table neatly setup there. And so it stayed there for 3½ years. (half a year ago, the windows was replaced, so this is no longer a thing) I should add that I live in Sweden and winter is cold,, and I had to seal the gap in the open window with cotton and old papers, and it worked pretty good, almost. (the really cold days was a bit chilly.) The balcony is outdoors, but has glazing, so rain doesn't get inside. It made for some really good temps during the wintery half of the year. But, Once more I find myself being fed up with the noise and heat generated. (the stuff is on a bench under the window now, on the inside.) it is currently 2am, the temperature is 31ºC ,,I guess 90+ F-units, which is maybe not much to a californian, But my Nordic genes can't handle it, at all!

Interesting vid Jay. Love when you test out some watercooling hardware. Genuinely learned new things in this one.

Jay I got one.. and I haven't seen this done before. Create a submerged build. Mod peltiers in an external loop that cools the fluid of the tank. I imagine that this could be done with a giant heatsink maybe in the bottom of the tank that can't be seen. When I say Mod a heatsink, think o-ring of a CPU block. So fluid would not cycle the oil of the submerged build. However that brings up another point if the pumps could somehow circulate mineral oil there would be no need to mod a heat sink in the case. Since peltiers cause condensation which would ultimately destroy the electronics. I figured the way to avoid this problem is the following. It would be interesting to reach those temperatures without using an exchange, and avoiding destruction. And if any company makes money off this idea I want at least 10% ;)

and as far as CPU goes, unless your case restricts the size of cooler you can put in a PC, its good aircooler (ahem, Noctua NH15 ...) or custom loop only time AIO actually is relevant is small form factor builds. AiO for midtower and bigger PCs is a downright stupid as you do not get any cooling benefits over aircooling in performance (unless you go to 320 or bigger radiator) for about DOUBLE the price, and get all the inherent risks of watercooling. and as sayd above its pretty eveident what is superior between custom or AiO as AiOs use shitty integrated pump and ALUMINIUM radiator and block where proper custom loop uses industrial grade pump with nothing but copper.

which is incredibly loaded question what case what CPU what GPU do you want to cool CPU only or GPU too what is your budget what ambient temperature will that system run in how long it will run per day how long will it run under full load do you plan to overclock or not what fan speeds do you intend to run how many fans you intend to install ... depending on several factors custom loop might run just a little bit better temperatures than AiO - if you build it badly, choke it in a small case, undersize the radiator for the application etc - mainly thanks to its better (and much more expensive) copper components and stronger pump, or it can drop your temperatures to near ambient for true overkill loops on undervolted temperature focused builds ... if i can give an answer you are obviously looking for - price / performance of custom waterloop is HORRIBLE, proper watercooling loop will cost you a LOT of money for just small temperature drop when compared to proper aircooling (the temperature gain is MUCH more significant on GPU than on CPU) - where Watercooling shines is SILENCE - put proper WC loop in silence based case and not only you will run heavily oveclocked components at lets say +20 degrees over ambient but run that system near silently. Same cannot be sayd for AiOs with theyr generally small radiators and cheap fans that have to run much higher RPM than on bigger, properly sized COPPER rads on custom loop. or if you want real world example, my loop dropped about 15 degrees from the CPU and 25-30 degrees from my GPU when compared to aircooling (my Noctua NH-D14 was basically same performance cooler as 280mm AiO ...) - that might look nice yes? ... well until you consider that the loop cost me +-$1000 ... and that doesnt include price of my BeQuiet Darkbase PRO 900 case to actually be able to fit that build in ...

I used 2x 360mm X-flow in my H700i for the reason you said about not having to run any tubing from one side of the case to the other. Also gives my a true 'low point' for my drain tap on the front rad to drain nearly all the liquid from the loop. Had to have the front rad in push (fan between case & rad) because the end caps interfered with the case due to the extra size. So i encountered the both of the Pros & Cons you mentioned...

The pressure drop can also be measured just by connecting them to the pump and adding a flow meter. Maybe this can help to?

Hey Jay, love the channel man! In helping people with their computers over the years, I have noticed a lot of common mistakes in where they place them and how it affects cooling.

Thanks for the vid Jay, I totally agree. I use the Alfacool Crossflow 480mm x 45mm radiator in my ThermalTake Core P5 (with a 7700K delidded&oc'ed + Strix 1080ti oc'ed) and there is literately nothing I can do to my system to over saturate the radiator to the point that it's not enough cooling. When it comes to PC components and water cooling both crossflow and dual pass work equally as good. Maybe in a car dual pass makes a difference but in pc's it just doesn't. So I agree with Jay. The 'fins per inch' is the only thing that actually matters. Buy based on FPI needs first. Then aesthetic and port layout if needed.

I built my rig with 2 alphacool crossflow radiators to minimize tube clutter in the case (I like a clean look). As a result I could skip a good 60cm of tube because the radiators covered that distance for me, resulting in a super clean build that I'm really happy with. And the thermals are still great. The difference between a u-flow rad is negligible, 1 degree at most.

Love your videos Hello from estonia

Hi Jay, 1st off thanks for all of the great video content, I try not to miss a single video. My question is, wouldn't the testing be more accurate if you measured the fluid temp going both in and out of the rad? If I'm wrong please say so and why...thanks.

Hey Jay! It was surreal running into you at Guang Hua Digital Plaza. Thanks for stopping and chatting for a bit! You mentioned SFF--I'd really like to see you water cool and overclock and go the whole nine yards in a "properly" small form factor case, like less than 10L volume.

Jayz love your vids

hello I have one of these crossflow rads I did not know how to use it properly I used two of the outlets on one end not in diagonal (I used it more like a traditional rad) and my temps where really bad for 2 years I stumbled across this video and you saved my temps was blaming the xspc brand hating myself for not buying ek lol and whole time I was using my crossflow 360 radiator wrong wow thank you

Thanks for the Demonstration....Figures they would be about the same temp...

I never even knew there was a "crossflow" radiator. That would've been handy in building in my Obsidian 250D. Also thanks for making a blooper reel, that was good.

ok im like 3 and half minutes in, I had no idea you could get quick disconnects like these. I'm getting a parts list together for a x299 build and I want to build a custom loop for it so thats why I'm here. glad I learned something new already lol

Quick disconnect fitting rearrangement would be awesome as a "carnival" game with a prize at LTX next year.

Seeing those quick disconnects in action blew my mind lol

I've learned so much on cooling from TwoCents - as in actual tested facts - which is way more helpful than hype or misinformation (Thanks Jay)

i miss these kinds of videos good video

Hey Jay! So this question is a common question in heat transfer questions can actually be answered analytically by finding the "NTU" or the number of transfer units. So since these would both be categorized as a cross-flow heat exchanger (as opposed to co/counter current when you're cooling a liquid) the difference between the crossflow and dual pass would just be the surface area and length. Since the NTU is (heat transfer rate *Perimeter * Length/ mass flow rate* heat capacity) Essentially it comes down to a direct ratio surface area/mass flow rate. so whichever one has a higher ratio will perform better!

those quick-connects are a godsend

Jay just want to say thanks after watching ur shows I felt I would be able to do water-cooling in my system but then I seen the cost and all I can say is wow!!$$$ But then I seen ur show on EKWB 240g so I order it and just got it all up and running and from ur show I knew what to look for and what I was doing. Keep up the great work and thanks again. If anyone in the comments is wondering if they should buy it if u have the money its great it drop my temps on my gpu a buy 20c (FE card) and is even better on the cpu than the corsair AIO I was using. thanks for all the info ur GREAT!!!

Jayz really shows us how to age in style. Thumbs up for that white hair~

I want crossflow, not only because the fluid restriction should be lower. But like you said, you can run your lines more efficiently, which I like a lot.

From my testing, I got the exact temps under load crunching and folding. My testing went for about a week straight per setup. I personally say to with what setup of rad fits your case best.

I have never had any intention to water cool my pc, but this video was still interesting.

Good vid Jay! I’m using an AquaCool 360 Crossflow in my build along with a 280 rad from EK. I’m cooling Ryzen 1600 and a 1070. Before I bought the rads, my cpu would thermal throttle 3.8GHz. I was able to get fast speeds, but the voltage required would 85c. After installing the loop, I’m able to max my Ryzen out at 4GHz. I’m not at home, but iirc, my cpu temps are 40-45c on prime95 and my gpu sits around 38-39c on Valley.

What brand are the quick disconnects do you have link to them ? Thank you for testing I was wondering about this this week? Thanks for all your work!

I know this video is a year old, but its worth mentioning that commercial water chillers come with options to do single or multi pass loops. Multi-pass being the most efficient, as the fluid spends more time in the heat exchanger (HX), allowing for more heat to be dissipated. There is a point at which you will experience diminishing returns beyond 2 passes, as most of your thermal exchange, about 80 percent, is done in the first pass. Granted this is all dependant on the shape of the tubes or in this case the micro channel the fluid passes through.

That’s cool Now compare them with the D5 and the DDC water pumps. That’s should help show between laminar flows. Laminar flow with Poiseuille's Law. We had to learn this with our vented patients in the hospital. Thanks Jay.

Started overclocking my ryzen 2600 thanks for your info on pc's..i got it stable at 4.0g air cooled 68c mem from 2.6g to 3.2g and 1070ti at 2086mhz

here's a hard but interesting to do suggestion for a video.... hook your loop up to the kitchen (or garden) tap and see what the difference in temp is between a single pass (where loop order may actually affect temps of different components) and a normal closed loop configuration. would be fairly easy to do with the quick disconnects

I like crossflows on top and duals in the front/front side. Makes the connections easier. Some cases can't fit an x-flow on the top (in the back) without angled adapters though.

You should look at the heat distribution across the radiator with one of those neato IR cameras. That way, we can see if the dual-pass is rewarming the liquid on the way back, or we can see if the crossflow radiator is hotter on one side than the other.

Once again... Jay half-assed a project... What is the point if you don't saturate the radiator? So all you proved is that they both cool those components... Super helpful.

Do a video on case airflow and what cases have the best airflow and how you should set up your fans and where the best places to put radiators etc.

I got the Corsair H150 AIO b/c of JayzTwoCents. It's my first step into water cooling, and hopefully in a year or two I'll move towards a full custom loop! :)

Great video. I enjoyed it.

Full ek water block installation video using their kits would be really cool

Yay for more water cooling content!

This video needs a conclusion portion with a summary table displaying the results for a side-by-side comparison.
