Thermaltake Pure Duo 12 ARGB Sync White 2-pack 120mm case fan CL-F097-PL12SW-B

Dual 120 mm ARGB fan kit

This two-fan pack adds addressable lighting and PWM airflow to a white-themed build. Each unit carries eighteen LEDs split across two independent rings that sync with 5 V motherboard software. The hydraulic bearing and nine-blade design target quiet operation at up to fifty-six point five one CFM. Anti-vibration pads are moulded into the corners for simpler mounting.

Sustained-load acoustic profile

Between five hundred and fifteen hundred RPM the fans move air steadily while the hydraulic bearing self-lubricates to limit friction noise. At full speed the quoted sound pressure is twenty-eight dBA, a level intended to stay unobtrusive during long rendering or gaming sessions. The PWM curve lets the motherboard taper speed once thermals stabilise, so noise does not ramp unnecessarily. No separate controller is required once the 4-pin header is connected.

Deciding specification — 5 V ARGB header required

The dual-ring lighting only functions when a compatible 5 V addressable RGB header or the supplied controller is available. Builds limited to 12 V RGB or lacking any RGB header cannot drive the eighteen LEDs per fan. In that scenario the fans still spin and cool, but the primary visual feature remains inactive.
