Frequently Asked Questions

Q: How does Granzon differ from the standard Bykski line?

A: Granzon is Bykski's premium sub-brand. The cold plate is the same nickel-electroplated copper construction, but the base and top are wrapped in full aluminum armor for a heavier visual finish.

Q: Which Gigabyte RTX 4080 cards is it compatible with?

A: Gigabyte RTX 4080 16G Eagle, Aero OC, Master 16G and Gaming OC 16G. Other 4080 variants (Windforce, AORUS Xtreme, AORUS Master) use different PCBs.

Q: Will the aluminum armor cause galvanic corrosion?

A: No. The aluminum armor wraps the exterior only and is not in the coolant path. The only wetted metal is the nickel-plated copper cold plate, so the block is safe in standard copper-radiator loops.

Q: What thread size are the ports?

A: G1/4 inch, on both top and bottom edges for serial or parallel routing.

Q: What is in the box?

A: One full-armor GPU block with backplate, mounting hardware
