yeah you can't run your cards that way they're gonna overheat your noob don't you know that the fluid will just pass right through the first card and not even cool it so disappointed J thought you actually knew something about water cooling yeah this video is just a little overdue if I had a dollar for every single time somebody told me that I was doing my parallel configurations wrong and then it wasn't going to work and that the cards were going to overheat ever since I started doing red mist and then skunk works and now skunk works version 2.0 I would be able to build another Tower because I'm telling you right now there's an awful lot of misinformation and just flat-out unexperienced people out there claiming to know that parallel configurations with the inlet and outlet on the same side won't work now let me tell you what they think is happening and then I'll tell you what's really happening now in order to try and keep it simple on what they think is happening I'm going to use a two card configuration example rather than the triple card configuration like I have but rest assured the fluid dynamics are exactly the same whether it be 1 2 3 4 5 10 or 5000 cards the fluid dynamics will remain the same now what they think is happening is that the coolant will enter in the first card that was actually a pretty dirty gesture wasn't it's going to enter in the first card sorry pass straight through it because they think that the fluids going to go oh we don't want to go through that block we want to go to the you know the farthest point out there which might be Pluto I don't know but in this case they think it's going to pass right through the first card go through the second card back down through the first card completely ignoring the first card altogether or at the very least I've heard some people say well the card will fill but the fluid won't go anywhere it'll just sit there because it's like traffic the fluid can't it's got its blinker on but no one will let it in the fluid just sits there in the card because the flow in and out between the actual inlets and the second card are taking up all of the space and that fluid has nowhere to go now that is a whole bunch of horseshit it work that way people what actually happens here is the fluid wants to take the travel of least resistance now how is it going to do that when you have two blocks in there easy it's going to split the flow evenly between the two if there's an if on this if both of the blocks are identical if you put two different blocks in there you're going to end up splitting the flow between them but it's not going to be an equal split because the least resistance block is going to get more flow and the high resistance block is going to get less flow that way you have an equal Inlet and outlet flow rate now all of this works because of two major principles that is path of least resistance and flow rate as long as those two things are present no matter what the cards will always get equal flow between them not even hurt some people claim to be experts to go as far as to say well you have to add some sort of resistor into the top card otherwise you're not going to introduce enough resistance forcing the flow that's bypassing the first car to actually make that 90-degree Bend I know I'm a scientist I train Stephen Hawking I mean that's what so many people actually think now there's something else that people tend to think is going to happen when you have a parallel config and that being that one card is going to suffer dramatically versus the other card in terms of temperatures now that's not actually true in fact I have found that temperatures are a bit more stable and equalized between multiple cards when you do a parallel config because the temperature of one card is not influencing the other all the naysayers saying this isn't going to work this is it going to work Jay you're just doing it because it looks pretty and you don't want to admit that doesn't work right that doesn't make sense that's like I can't even wrap my head around that one no matter how much I try so let's go ahead and guys I've had a valley benchmark running in the background long before this video started during this entire video in fact I've even had if you can see it right there a thermometer set up or not monitor but it's a it's an air meter it measures the airflow this is how I know that my fans are actually working oh and I want to point out something else this whole test was done with airflow fans AF 140 fans on remember how people say airflow fans don't work on radiators blah you're dumb so we're kind of like just bustin all the myths on this one aren't we so I've got a temperature probe on there and right now the intake temperature to that radiator because this room is freakin hot right now because I've got three graphics cards dumping heat into the atmosphere it's 81 degrees or 80 point nine degrees Fahrenheit I don't know what that actually equates to in Celsius in fact I can find out let's check in Celsius that is actually 72 point two degrees Celsius and we are 80 point nine degrees Fahrenheit now if I stuck this on the outlet side of the the back side of the case it's actually bumps up to almost 90 degrees so why am I even showing you this I want to show you in fact we just went up to if you can see that you might be able to see because of the focus we just went up to 81 point one degrees Fahrenheit yeah it's pretty warm in here so the reason why I'm pointing that out is that if I was going to have cooling capacity issues and the way the flow is set up in a hot room like this it would certainly be more evident so let's go ahead and turn around and get into the computer and see what the temperatures actually look like all right so here is my Triple A parallel configuration right here it actually enters in this card first then splits off to there and then splits off to there so all three of my cards are getting one-third of the input flow rate because they are all exiting out one third well because you have three cards and they're going to divide the flow amongst them so now with the room currently being let's see right now it is currently yeah eighty point nine still in here so we're holding very constant which means my cooling system is not heating up any more than it is we are at full capacity and if we scroll over here right now and see if we can get that in focus the cards are currently sitting at forty seven forty while they're fluctuating 48 48 48 well I think we just kind of put this one to bed didn't we yeah hopefully we can actually see that let's go ahead and get the camera a little closer here sorry about the shakiness but I really just want this to be put to bed once and for all so as you can see the top cards 48 the middle card 48 the bottom card 48 yeah there you go now again I'm sorry about having to point the camera at the screen but here is our MSI Afterburner from when we had those tests running and I just want to show you top card max temp 50 degrees uh let's see oh sorry there we go top card max temp 50 degrees middle card max temp 50 degrees bottom card max temp 49 degrees now you guys saw when we were doing the test they were actually sitting more like 48 those are max temps right there they don't actually show me the average but as you can see myth busted so there you go guys James two cents busting the water cooling troll myths out there and all I want to ask of you is if you guys see any forums or any other posts or comments of people saying you can't do inlet/outlet on the same side of a parallel configure them this video because I know it's not going to shut them up overall but at least if we can just get some people educated and we create this army of people saying parallel configs do work with inlet and outlet on the same side will make the water cooling enthusiast community stronger as a whole hope those videos helped you guys once and for all this videos overdue but better late than never I hope you guys are enjoying the videos I'm doing here on x99 and whatnot follow on Twitter if you guys have any questions about this now hopefully this video made sense to you guys if not just ask me your questions I'll do the best I can to actually answer them in a manner which you can you can grasp it because I know it's kind of a weird concept it's like it's like helicopters physically speaking they just shouldn't work but they do whatever Jase your sense guys thanks for watching and I get the heck on out of here see you next
