Bykski Armored End Port GPU Waterblock with Backplate for ASUS ROG Astral GeForce RTX 5090 32GB OC Edition (N-AS5090ASTRAL-X)
The Bykski N-AS5090ASTRAL-X water block and aluminum backplate cool ASUS ROG Astral GeForce RTX 5090 cards. A CNC-machined T2 copper base cools the GPU chip, while thermal pads transfer heat from the memory and power stages.
Coolant flows through 56 micro-channels with 0.3 mm jet spacing across 10,962.06 mm2 of surface area to lower operating temperatures and remove fan noise. The clear acrylic top displays fluid flow through the cooling loop.

Warnings
Warranty is repair or replacement. All returns are accepted within 30 days, no questions asked. An installed or used item comes back at a higher restocking fee.
The top is acrylic. Tighten mounting screws evenly and finger tight - over-tightening cracks acrylic, and a cracked top is not covered. Installation removes the card's stock cooler, so never power the card without the loop installed and the pump running. Thermal pads go where the block has corresponding raised contact points; the die itself uses thermal paste.
