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.
- 80 mm square chassis or equipment mount only; verify hole spacing and depth. CO identifies the continuous-operation dual-ball-bearing 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
F8 is an 80 mm form factor and does not fit a 92, 120, or 140 mm mount without a specifically supported bracket. PST does not raise the host current limit.
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.
