Multiple Voltage and Wide Speed \u200b\u200bCoverage<\/h3>\n

Available in DC 12V and 24V versions, with rated speeds ranging from 2500 to 7000 RPM, easily matching different power supply environments and cooling requirements. Clear labeling of “7038 Fan 12V Parameters” facilitates direct customer selection.<\/p>\n

Silent Operation Design, Minimum 23dBA<\/h3>\n

Utilizing hydrodynamic bearings and dynamic blade balancing, operating noise can be as low as 23 dB, equivalent to whisper-level silence, suitable for noise-sensitive desktop devices or home servers.<\/p>\n

Sleeve\/Dual Ball Bearing Options<\/h3>\n

Default configuration features long-life sleeve bearings with low friction and excellent quiet performance; a dual ball bearing upgrade option is also available, maintaining an ultra-long lifespan of 50,000 hours (constant 25\u2103 test) under high-temperature environments, suitable for 24\/7 industrial equipment.<\/p>\n

Intelligent PWM Temperature Control Speed \u200b\u200bAdjustment (4-pin Version)<\/h3>\n

The 4-pin interface supports motherboard PWM signals, automatically and steplessly adjusting the speed according to temperature, balancing heat dissipation and noise. It also offers 2-pin (basic power supply) and 3-pin (with speed feedback) versions, compatible with various main control boards and drivers.<\/p>\n
