Host compatibility and handling
- No CPU socket compatibility is claimed: this is a chassis/radiator fan, not a heatsink. Match the frame, mounting-hole pattern, depth, and airflow direction to the case or radiator manual.
- 120 mm case mount; its F-series airflow profile is not an automatic radiator replacement. CO denotes the dual-ball-bearing continuous-operation model.
- Before using a PST lead, calculate the combined current of every fan connected to that output; do not exceed the motherboard or controller channel rating.
- Keep motor power/control distinct from any lighting connection. Match exact pinout and voltage to the host manual; never force a keyed plug or connect an addressable-lighting lead to an incompatible 12 V RGB header.
- Unplug the host before installation. Keep fingers and loose wiring away from blades; replace cracked frames or damaged cables and investigate bearing noise rather than blocking a fan.
Model notes
PST can share a compatible PWM signal with a downstream fan. The host header still supplies the aggregate load; verify its limit before chaining.
Vendor airflow and pressure ratings are model/test-condition specifications, not a guarantee of the same result in a particular case or radiator. Confirm installed fan curves, actual clearances, and host current budget.
