Pack of ten 80 mm ball-bearing 24 V fans for server and inverter cooling
This lot contains ten new Jamicon JF0825B2HSAR square fans measuring 80 mm by 25 mm. They are intended for technicians maintaining inverter enclosures, server chassis or industrial cases that require 24 V DC airflow. The black frames and three-wire leads suit standard monitoring headers.
Each unit runs at 24 V drawing 0.15 A and uses a ball-bearing motor for continuous duty. The three-wire connection provides tachometer feedback so the host system can verify rotation. No LED lighting or PWM control is present, so speed is fixed by voltage.
Installation is a direct plug into any 24 V three-pin header with matching pin-out; the 80 mm square footprint matches the JF0825B2HSAR mounting holes. The only common issue is reversed polarity on the sense wire, which stops RPM reporting without preventing the fan from spinning.
Measured against everything we stock in CPU Coolers & Heatsink Fans, at today’s prices. Recalculated every night.

Each unit draws 0.15 A from a 24 V supply, so power consumption is determined by that voltage and current combination.
The third wire provides a tachometer signal for monitoring RPM; voltage regulation on the power lines is the only way to adjust speed.
Yes, the 80 mm square frame with 25 mm thickness matches the common 80 mm mounting holes used in cases and server racks.
