The Water Devil Cyclone

[Petey]

Hello I just switch from a bay res, that I've always used to a tube res, Bitsopower 250. How do I prevent the water cyclone. I'm going to mount inlet and outlet at the bottom. I have the the water pipe on the return keep hot water at top and take cool from the bottom, in theory anyway. Will I I have a cyclone effect if I don't use that restrictive plug. The water will be filled near to the top, to prevent starving pump. The hole to the top of case, verical mount d5 will be running at 24 volts, so a little more power will be applied. I would appreciate any help before I fill the thing up and have to find out the hard way. Didn't know if there were any high power pump concerns, or dual pump concerns.

I guess no one knows

well ... i am a newbie in watercooling, since i just did my dual loop CPU/GPU recently, but i use 2 tube res with bottom inlet/outlet.

tho i am not concerned by the "keep the hot water above in the res" since i use a Res>Pump>Rad>Block setup on both loop (to prevent the pump to add more temp to the water), if by water devil you mean cyclone/maelstrom effect ...
i use a Alphacool Coolplex 10 (CPU) and a Phobya Balancer 150 (GPU) the balancer have a separation between inlet and outlet and the Coolplex have a plexi tube in the inlet, i do not notice cyclone in the res but i use 2 Phobya DC12-220 pump

so my experience might not be what you seek as a answer.

So basically I take it wont vortex, Maelstrom, water devil, Toilet Water, if holes at the bottom are separated like your alpha cool Res, figure your pumps are smaller than d5 type but your at very low restriction and travel with separated components. Looked every where and no one explains the vortex effect, only say it happens. I guess put it together and hope for the best, just sucks when you want the facts.

ahahah ... yep ... that would be bad to have that one in a res

just sucks when you want the facts.

yep it would, tho the only time i had that effect was when filling the loop, and yes the DC12-220 are the lowest 12v pump from Phobya they have 260 and 440 aside but these are for 2.6 and 4.4m loop, so out of knowledge i thought the 220 would be sufficient and judging by the temps of my 290 and 4690K i was not mistaken, i went the hard way only looking for layout setup (res>pump>rad>block) and figuring out the rest myself once i got the pieces

you mean a plug like that one right? well that doesn't seems too expensive if one will be needed (or 2)

In order to avoid hot water going to the res my set up goes this way:

Res>pump>Gpu1>Gpu2>480Rad1>CPU>240Rad and back to the res.

 

[GreiverBlade]

Res>pump>Gpu1>Gpu2>480Rad1>CPU>240Rad and back to the res.

well in that setup you have some heat added by the pump, putting the 240 between pump and GPU1 would be a bit more efficient from what i heard

the water in the res do not need to be cool technically and if it is : the pump will ad some heat to it
but as i said i am new to WC loop and that advice i got it here (i think it was erocker or another mods from the site who suggested that layout)

Heat transfer and water temp will stabilise over time. The placing of components will have a minimal effect after the temperature has reached a stable level. The rate of flow (pump) and cooling capacity (rads) will determine the overall effectiveness of the loop. It does make sense though to have a rad between heat areas. My system is not that fussy though: 30cm tube reservoir>D5 pump>360 rad>360rad>cpu>gpu1>gpu2>back to reservoir.

So my temp increase carries across three active components but is then mitigated by 2 360 rads (6 fans). It would be interesting to see the temp at reservoir versus temp just before cpu.

well ... i intend to buy some temp probs to check res some day, but i still take for given that the pump still add heat to the water it push so for me the Pump>rad>block make sense even with the temp stabilization over time, but again i use a dual loop with 2 240 (1*30mm 1*60mm) for me the temp inside the res is irrelevant due to that layout i could also put a sensor cap on my Kryografics outlet to check the outgoing water temp, i wonder ... well i guess my next upgrade and tinker will be playing with the loop to perfect it to my liking ... actually it's rather straighforward without fancy and i don't mind taking it apart and redo it once i get better idea or tips

but the question of the OP is not about temperature stabilization momentum but rather about cyclone effect on a tube res outlet

I was waiting for you to say that, I used to think like you setting a rad between pump and GPU, but it's not worth.

well Barbaric has his rad after the pump which support my saying

again you did not answer the OP question : do you notice cyclone effect in the outlet of the res

+1 totally agree with you.
I am not a Watercooling expert But so far here on TPU i've learned a lot about it, the most important thing in a Watercooling setup is Pump after Res, but that's something that all of you already know.

the water in the res do not need to be cool technically and if it is : the pump will ad some heat to it

I agree with you about that, but my theory is cooler water in the res means less heat the pump transfer.

Really it doesnt matter much but to get the cleanest shortest tube routes you want whatever you are cooling in a series. so CPU block straight to the GPU block. Have radiators in between blocks is a waste and doesn't effect anything in a positive way once the system hits equilibrium, which is pretty much a couple minutes after the system has been running.


Yep, I had the same mentality when I started with water cooling till doing a lot more reading and @MT Alex pretty much convinced me the other way.

Might as well just do completely separate loops if you want to have radiators in between each block.


Seriously!? So what you want to get a little radiator and run it inbetween each GPU, again its not going to make a damn difference!! Put more stress on your pump due to the extra length of tubing it has to pump the water through, look really messy with tubing all over, and not benefit temperatures at all, I mean hell look at your current setup. That huge 3 ft long piece of tubing going from the 480 to the pump is something else.

Though this is not my system so what you do with it is your choice, but if you want to go for a good looking loop as well, you wouldnt be running radiators inbetween blocks. You would be doing the shortest most direct routes for a cleaner look.


@RCoon
It doesn't matter where you put components in what order in your loop, the entire loop will reach an equilibrium in temperature regardless. The order MIGHT make a difference in max temps for the first 10 minutes from a cold boot. After that, there is literally no difference. I've built plenty of loops, small and large. One of which had 3 GPU's, 1 CPU, 240+240+480 rad, and a single 750lph pump. I had put components wherever they were simpler and easier to install. I did not put them in any mythological order to improve temps. That whole ideal is a fallacy. Make it easy for yourself, connect the components in the easiest order, and the best order so they are even easier to maintain.

Either put them in separate loops, or put in a T junction connector with some quick disconnects so you can drain your loop easily.



@manofthem
While i have the water from my 2 gpus going directly to the res/pump and am cool with it, I understand the whole thing about you not wanting hot water going to the res and pump, though any thermal difference imo is small.

Today this is how my setup looks, i thank TPU and especially:
