Artifacts

Graphical anomalies, usually caused by physical damage or unstable overclock of GPU or RAM IC.

Air Flow Fan

See Case Fan.

Air Flow

Air flow is a movement of air, usually generated by any form of fan. The higher the airflow, the better the performance.

Acrylic

Polymethyl methacrylate (PMMA). See Plexi.

ACF

EK’s Advanced Compression Fitting. Comes in many varieties and doesn’t need any clamps to secure the tubing.

Acetal

Durable technical plastic, also known as POM, a popular material in the liquid cooling industry. See What is the difference between acetal and plexi?

D5

A renowned cylindrical high flow liquid cooling pump from Laing/Xylem. Quiet and powerful.

Case Fan

A cooling fan, intended for ventilation of PC chassis. Built for high air flow but does not generate much static pressure. Not recommended for radiator cooling.

Bow

Refers to the curvature of the contact surface of water blocks (usually in reference to CPU blocks). The bow angle and type (concave/convex) can be changed depending on the application and is intentionally designed as such.
