Low flow in Alphacool Eisblock Aurora Plexi GPX-A Radeon 5600/5700 XT Pulse / Mech & Evoke

[kluczyk52]

Hello, I recently bought an Alphacool Eisblock Aurora Plexi GPX-A Radeon 5600/5700 XT Pulse / Mech & Evoke block on MSI EVOKE OC and unfortunately it restricts the flow terribly. The pump with the flow meter alone packs 540 l / h, and after connecting the GPU block, max 90 l / h. I will add that when testing with the CPU block, it packs 420 l / h so the pump works properly. The pump is a new D5 PWM. What can limit the flow in the block?

Hi, yes some of our blocks are restrictive but not that much. Something is not working properly with this block. The fins are clean and not clogged right? Have you checked the jet plate? Where have you bought the product from?

The fins are clean, connection on the left input, right output. Of course, I checked the jetplate is ok. I also changed the plugs to other, shorter ones. I opened the whole block yesterday to check what could be the cause, unfortunately I did not find a fault. Further below 100 l / h after folding. I bought the block in Poland at www.angela.pl

If you need to, I can send you better photos. Photos of the rolled block. I do not like the exchange, and the more I have no alternative to my graphics card. Besides, I like your products

I like your products

Thank you very much for this we do appreciate it

Yes please upload some more photos maybe we can see something which is not correct.

I send some photos and leave the block open for today in case you need a more precise photo.

I dont see anything wrong. I would love to show this pictures to my colleaugue who has done the technical draws for this block but he is on vacation. He will be back by Monday. Is it okay for you to wait until Monday? If yes please PM me by Monday and i will let you know with the result.

Hi again. After i have talked with my colleague there is nothing wrong with the block or we could not see any failery on it. 90 lt/h is a good flow and what makes me wonder is the flow rate (540 lt) of your pump. Which laing is this exactly? Non of this pumps can provide that much flow. All the D5,s that we have tested here can provide maximum 300 lt an hour. With a pump which is that powerfull you can not run the system. Our connections and blocks are tested up to 1 bar. The tubes should pop out under this pressure. But i also have to admit that this block is a bit restrictive due the size of the inlet and outlet.

My pump is a D5 PWM from Aquacomputer.
The flow of 540 l / h is obtained on the reservoir and flow meter with the pump speed of 4850 rpm. Flowmiwerz is High Flow from Aquacomputer. I got a few opinions on various forums and they all agree that no block at this pump and rpm 2500-3000 rpm. it should not go below 100 - 120 l / h. let alone at 4850 rpm.
Just out of curiosity in what direction exactly is the liquid flowing in the block? IN-> Jetplate-> VRM-> OUT or IN-> Jetplate-> OUT and VRM-> OUT

Exactly; In -> Jetplate -> VRM and Out.

hi

have you run your card with this yet? wanted to see what kind of temps your are getting? is it a 5700 card you have?

thanks

Hi, I have a MSI 5700XT EVOKE OC, the temperatures are ok. The card under stress does not exceed 50 * C only this flow ...

is that junction temp?

I dont think so .
