9025 12 V PWM case fan

The DA09025B12U is a 9 cm round-frame case fan that operates at 12 V and uses a four-wire PWM connection for speed control. It is intended for builders who need a compact cooling unit for CPU heatsinks or tight chassis locations.

Double ball bearing simplifies mounting

The double ball bearing design allows the fan to be installed in any orientation without affecting longevity. The only common issue is ensuring the four-pin header matches the motherboard PWM layout, as a three-pin socket will remove speed regulation.
