Pump and rez issues…

[Rebootableglitch]

I have a thermaltake 900 case and a alpha cool UT60 560 and a XT45 280 at the back of the case, and I have 2 D5 thermaltake pump rez combos


It is all soft tubing 3/4 1/2

now for whatever reason I could not get this to work? Maybe I am doing something wrong so I need a bit of help and advice..

now as far as I know it’s in out in out that’s how it’s supposed to go to make a loop right? But for whatever reason I could not seem to get it to go it filled up the left pump every time to like when it was bursting like it trickled in over time and it seemed like the coolant just sort of trickled into the second rez from the 280 rad… am I like missing something? And for my troubles I ended up wasting 2 L of coolant… cause well let’s just say it didn’t work and I needed a mop bucket >_>. Any help would be amazing!!! Or advice, oh I almost forgot I am trying to push it into a single block one block 2 rads 2 pump/rez

Pictures would help.

If you have 2 Pump Rez in the same loop, the air has to be bleed out somehow. That could be your problem. Air is trapped in the second one. Haven't seen this setup before. Its always 1 Pump/ Rez per loop.

 

[Rebootableglitch]

Mmm the air thing would make sense considering the what I was seeing in the tubing on the other side of the blocking from in to out and into the other Rez there was like a fight going on the coolant seemed to play ping pong with an invisible pong ball bouncing back and forth the distance never closed but seems to keep the same distance going back and forth.

I would take pictures but I had to take out everything to clean up the mess it created the entire bottom of the case was flooded

Would one D5 pump do both of those rads and the block? I honestly Did not think it was able to do it.

IR_cow?

Hi,
Yeah only time I've seen two reservoirs used if one did a cpu and gpu loops separately.

Having two reservoirs is obviously not needed and overly complicates loop pressure.

So with that in mind not sure it would work well at all either
You sure couldn't use both at the same time filling the loop as you say they counter each others operation.

You'd likely have to use one pump at a time and switch once the other reservoir gets over full then kick it on and disconnect the other and repeat until the loop is full.

Then cross your fingers and use both and see if the mess returns hehe.

If you want to use two D5 pumps there are two options

Get a dual D5 pump body ek makes one it does not have a reservoir you just tube off one to.

EK-XTOP Revo Dual D5 PWM Serial - (incl. 2x pump)

EK-XTOP Revo Dual D5 PWM Serial is a fourth generation high-performance aftermarket DUAL pump top (volute) for D5 type water pumps, pre-installed with two EK-D5 PWM water pumps.

Or get a D5 top "this is what I used on my dual D5 pump setup" which has no reservoir and at this point is your cheapest option ek has one for around 90.us

@Rebootableglitch
i would start with one res/pump first, to see if all works as expected.
dont waste money on EK, other brands usually are cheaper.

i dont care for EK, as at those prices, i expect "flawless" products
(not high failure rates on some of their things)

dual pump top

 

[ThrashZone]

Hi,
Yeah I just posted something I knew about hell TT might have a single d5 top op can use instead of the additional reservoir combo.

 

[Waldorf]

@ThrashZone
lol, all good.
just dont see their products/quality matching price consistently, considering they call themselves a "premium" brand.

its like bmw talking about their driving "machines", yet need to release a special edition of a special edition (M3 CSL)
to be able to beat the RS4 (V8)..

 

[Vya Domus]

If you have another reservoir depending on where the inlet/outlets are you're gonna need to flip the case around to get the air out, there is no other way to do it. But can't you just fill it up manually ?

I was thinking just unscrew the top and fill the second one as well. Of course off or the water will go everywhere.

Hi,
Yeah flow wise not sure how well that is lots of rad space
You don't list which water blocks you're using or chip and gpu.
GPU blocks aren't an issue normally
CPU blocks can be a bit restrictive at least good ones.

Seeing you have two d5 pump reservoir combos for two loops really I'd do just that
Loop for gpu with one rad
Loop for cpu with one rad
Would be best.

Alphacool 560 ut60 and a second rad is XT280 though the 280 one sits higher then the 560 its roughly a third of the 560 high up maybe if I did the 280 first and let gravity carry it down into the 560 it wouldn’t have to travel as high up?

Ideally I wanted an ek block with an active backplate but they don’t make 3090 ek blocks anymore they have been marked end of life, so I went with a phantec glacier for the 3090. It’s just the one block with your advice I am probably going to split the two pump/reses to each side, one cpu one graphics card is still like the two rads on the video card though if it is feasible but it sounds like it won’t be :/.

Hi,
Well if you're still within your return window see if TT has one of these dual d5 pump setups.
Link is on post #5

 

[Vya Domus]

I have four rads, a single pump is fine. People used multiple pumps back in the multi GPU days.

 

[FireFox]

Yes, a single D5 is fine.
I have 3 rads, 2x 480 and 1x 420, single Pump.

1. Have you figured out what was leaking? You said that the bottom of your case was full of liquid...
2. Yes, you can use both res/pump combos together. Fill one up completely. Use the other normally. *Make sure all of your tubing runs are correctly plumbed so the pumps aren't fighting each other*
3. You don't need a dual pump top to run two pumps. Simply connect your second pump immediately after your pump/res (so it's always being fed coolant) be sure not to run it dry while filling the loop. Bumping the power to your pumps rather than running them for long durations works best until the loop is partially full.
4. Yes, you should be able to run a single d5 with your 560 and 280 once the loop is full.
5. If at any point you ran one of your d5s dry while initially trying to fill your loop there's a high probability it's permanently damaged. Don't use that pump going forward.

Oh no nothing leaking… pressure built to the point and the tubing litterly burst cause for whatever reason it was pumping coolant in faster then it was going out or there was a ton of air in it preventing it or something reguardless it went pop and then coolant went everywhere my looped drained out in less then 12 seconds before I realized what had happened lol…
I turned off the power just before the coolant ran out completely but ya it several L coolant wasted lol


nope nether of them ran dry as soon as it got close to that point I shut the power off at the psu I am running the loop outside of the environment with an external psu so only then coolant is being pushed through to get it started to make sure there’s no leaks or anything and once I make sure there are no leaks I put it all together start it up in the environment.

So what you mean if I understand it right, only fill one Rez and feed it directly into the other Rez so it constantly has coolant?

So esssentially turning on the second one to feed into the first one and constantly turn it on and off till the loop is partially full?

If you want to run both res/pumps at the same time. Fill one of the two completely up and just use the second for filling the loop (without powering up the one with the filled res) until the loop is full.

To use the second pump without the reservoir. You'll need the stock top that should have come in the box. If it didn't come with the stock top then you'll have to source a stock d5 top but obviously only IF you want to run dual pumps without the second res.

You have options.

 

[Waldorf]

@Rebootableglitch
make sure you install a pressure relieve valve on the res,
just the difference between winter/summer temps (to keep it simple), is enough to warrant one.
i prefer one with a gore-tex membrane, prevents water coming out if res isnt upgrade when doing stuff.

Hi
Yeah I said in post #4 use the second pump just as a pass through meaning No Power until the loop is full just using pump one to fill the loop

You could also switch once in a while when the second pass through pump reservoir gets full then turn it on and disconnect the first pump for a little while making it the pass through until that reservoir gets full.

Very important to have all tubing fully inserted and fittings tightened up 3/8-3/4" tubing is very stiff and turns can be fun lol so leave a little extra length.
