We build a custom water-cooling system with the following specs:
CPU: AMD Ryzen 9 3950X (16x 3,5 GHz) Board: Gigabyte Aorus Master X570 GPU: Gigabyte Aorus GeForce RTX 2080 Ti Xtreme Waterforce WB 11G RAM: 32GB G.Skill Trident Z RGB DDR4-3600 DIMM CL17 SSD: 2 x 1TB Crucial P1 NVMe SSD Power: 1000 Watt Corsair HXi Series HX1000i Case: Lian Li PC-O11DW Dynamic Midi-Tower Fans: 5 x 120mm Radiators: EK Water Blocks EK-CoolStream PE 360 + EK Water Blocks EK-CoolStream PE 240 Distro (Pump + Reservoir): Lian Li O11D Distro-Plate G1
(Full specs incl. water-cooling here)
After a while the first pump of the Distro Plate died, then after an upgrade to a pump twice as strong the second one. Then the mainboard died (because of a bad power supply which got replaced) and got replaced and now the third pump which was connected to an external power brick, died as well. We think we seriously did something wrong, but we can't seem to find the reason.
Our first loop was from Distro Plate split to GPU and CPU where each went into a separate Radiator and were merged into the Distro plate after this, but as we thought it might be the reason of the pump not working anymore, we restructured into two semi-separate loops one going directly into cpu and rad 1 and after that going into gpu and rad 2.
