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?
