JONSBO HF1215 Performance ARGB 15 mm Thin Case Fan Black

Ultra-Thin 15 mm Profile

The JONSBO HF1215 is a 120 mm case fan measuring just 15 mm thick, designed for builds where standard 25 mm fans cannot fit. Its slim frame suits compact chassis, radiator push-pull setups, or tight clearances around motherboard heatsinks. The fan uses a Dynamic Hydraulic Bearing rated for 50000 hours MTTF at 25 °C and ships with eight rubber cushioning pads to decouple vibration from the case.

Upgrade From Standard Thickness

This fan replaces a conventional 25 mm model when space behind the motherboard tray or between components is limited. The thinner profile allows installation in narrow radiator stacks or shallow cases without sacrificing a 120 mm mounting pattern. The performance gain is worthwhile when a thicker fan would physically foul cables, a pump top, or a large CPU cooler base, letting the builder keep full 120 mm airflow in a constrained volume.

PWM and 5 V ARGB Limits

Speed is regulated by a 4-pin PWM signal across a 700 to 1800 rpm range, delivering 13.1 to 62 CFM at 18.6 to 29.7 dBA. The addressable RGB lighting requires a motherboard 5 V 3-pin header; it will not function on 12 V RGB or non-addressable headers. Maximum airflow and static pressure are bounded by the 15 mm blade depth, so the fan suits moderate cooling loads rather than high-restriction radiators demanding peak static pressure.
