Watercooling pressure ?

[C.Ainsy]

I use to have a 480mm rad on the top of my case with a Laing d5 and my res mounted onto it I recently added another 480mm rad to the bottom of my case so now I have 2 now I have to keep the g1/4" plug in the top of my res becuase when I turn off the pc my water rises out the res is this normal becuase I didn't have to put the plug in before I added another rad any help much appreciated thanks

did you have the reservoir open always??? but why? it's supposed to be used sealed off

the water comes out of the radiators and is pushed back  into reservoir, that's normal, you reservoir should be at the highest point - above everything else

Oh no? You had your loop open to air? Uhh...  It's now filled with bacteria and algae and something's already gunking up. My bet would be the first block in the loop. Disassemble it and clean it and keep the loop sealed from now on. Boil everything you can while you're at it. And get new tubes. It costs a few monies but trying to get the slime off of the inside is a huge pain in the ass.

Could this be the reason I realised I've used a diffrent port this time the old port inuses had a tube thing going further into res ?

You're supposed to use the middle one.

Ok lol I realised when I took the picture will it be okay like that for a week or two until my gpu block arrives or do I need to drain it and change port

I get what you're trying to say, but so long as he has proper amti-microbial coolant in his system, then this is a non issue. In fact its often recommended that after building or filling a loop that you let it run with the fill port open for 24 hours so that it bleeds all of the air out of the system. And even if you didn't do that, whatever liquid you're using in the system (if it doesn't have proper anti-micribial solution in it) is going to be carrying a lot more bacteria than the air does.

 

@OP. You should keep your system sealed at all times unless you're bleeding it or filling/cleaning it. There isn't any good reason not to. keeping it sealed should fix your issue.

It should be fine but make sure to keep all of the fill ports closed.

I filled it up yesterday I'm using distilled water and a kill coil as you can see do I also need a biocide ?

- A liter or two of water has more microbes (and dust and dirt I might have added) in it than a few thousand liters of air? Really? Ok then.

- The fact that more and more dirt and microbes can access the system all the time is a non-issue because.. Err? The finite amount of anti-microbial additives can kill an infinite amount of microbes, maybe? Uh. Sure then. Ok.

- What I have actual trouble with is how do the bodies of those microbes disappear. Do the dissolve in the liquid? Do they turn in to gas and escape the system? Or are they so few and so tiny that they don't matter in terms of cooling? Or are they actually good for the system? What? 

 

I know this is not a biology class and you simply have your facts a bit off. The reason that the additives are so effective against bacteria and algae is that they're targeted against very specific microbes. You know, not all microbes can survive in a liquid with no access to gaseous oxygen. So by depriving the majority of them of oxygen and chemically killing the few that survive without it is the most effective method. 

And I know this isn't physics class either, but a well-designed loop will gather the air into the reservoir be it open to elements or not. You really only have to have the res relatively high in the system and the pump directly below it. You're thinking the air can't escape the system but it doesn't even have to at that point. Just open the top for long enough that you can top the coolant up. If there's no more air seeping into the system from open holes there's no need to remove air from it. If did generate extra air somehow, then yes, the pressure would build up and blow a gasket someplace. But it doesn't. Air doesn't just come to be in a closed system. Really the reason to run a long test is for the leaks. Flowing water is great for expanding hairline fractures in rubber gaskets and sneaking under the solder joints in radiators and what not.

So yeah, run a long test but with everything sealed up.

when it comes to living organisms, yes, liquid does (typically) carry many many more (a lot more than a few thousand times as many).

Dust and debris is a fair point, but the amount that will actually settle into a small open hole even in a non filtered case is minimal. And I would expect that in a system where he can fit 2 480's in, i should hope that he has air filters on his intakes at least. The reason for this is there is no air current flowing into the hole, and tons of air current flowing around the hole. anything being carried by the air will want to go where the air is going. SOME of it will fall out of the air and into dead pockets such as this hole, but its realistically very minimal

Poison is Poison. You're right that it IS finite, but you would need an incredible amount of microbes to overwhelm something like that. Enough to where you can begin physically seeing them with the naked eye. MAYBE at that point there wouldn't be enough poison left in the system to be effective against microbes. But that's just not realistic. Microbes only because a problem when they're allowed to breed. 1 becomes 2, 2 becomes 4, and so on. in these situations you can get millions or billions in no time. but if a couple hundred or a few thousand fall into a system of poison, they just die. they don't breed, and they don't become an issue.

Their bodies wont block anything. they're microbes. they will float around with the rest of the coolant just the same as any other material (such as colouring) in the coolant does. They cannot generate enough bodies to become an issue.

Good point. but opening the lid doesn't introduce air or oxygen into the liquid. the liquid is going to have the same amount of 0 gaseous oxygen in it as it always had. The properties of the liquid doesn't change just because its exposed to open air (with the exception that some of it can now potentially evaporate). So even opening the lid to air doesn't change which ones the liquid can or cannot kill.

This is not why air gathers in the reservoir. It has absolutely nothing to do with the placement of your reservoir. The reason air gathers in your reservoir is because all of your tubes, blocks rads, and so on are being filled with liquid pressure from your pump. the only place there isn't 100% liquid pressure is in the reservoir. with a strong enough pump, the reservoir could be 10 ft lower than your entire system and still be carrying the only air in the loop.

This is something you're actually correct about. Air wont enter the system. Although I'm not exactly sure what point you're actually trying to make here.

One very important thing to mentioned if you have any blocks that are nickel plated your best off to not use silver in the loop as they are borderline dis-similar metals in a loop environment. If there is nickel your better off with a premixed fluid or something like Petra (clear) PT nuke.
