Pic-1: Front of the box, not the most attractive colors but it does the job.

Pic-2: Side with features of the fan:?

  • Designed for the 1U/2U Servers Raid Storage (19" Cabinet), and for home appliance industries

  • Angle of 180 degrees for better air intake and outlet ventilation

  • Low noise with large air volume

  • Low electricity consumption

  • Fast and easy to install

Pic-3: Other side of box with specifications:

  • Dimension: 48 x 136 x 40.5mm

  • Weight: 191gm

  • Voltage: 12V

  • Current: 0.2A

  • Speed: 7400 RPM

  • Airflow 11.12 CFM

  • Noise: 38 dBA

  • Static Pressure: 1.84mm-aq

Pic-4:? The contents of the box, crossflow blower with a pass through molex connector, this isn't your normal case fan. Missing is mounting hardware and instructions, these would've been helpful.

Pic-5: View of top and back of the crossflow blower.

Pic-6: From the back of the blower you can see the 20 curved aluminum fan blades.? Each blade is 6mm wide and 9 cm long.

Pic-7:?The air comes out of the lower front of the blower.?

Pic-8: Here I placed the blower in the bottom front of the case, behind the front intake fan.? This is the position the fan will be in for testing.

Pic-9: Another idea I had for the blower, I put it in a 5.25" slot, it almost fit perfectly, just a little too short.

?Movie-1: This shows the crossflow blower in action.? As you can see in the movie, there is dead spots on each end of the fan, not moving very much air.

  • Pentium III 1 Ghz

  • 256mb PC133

  • Geforce 2 MX-400

  • Gigafast 10/100 NIC

Ambient case temp



Without crossflow blower



With crossflow blower



?Tests conducted with ambient room temperature of 20.8c.? I used Sandra 2002 Standard burn in wizard for load testing.? I let the system run for 30 minutes each time before taking a temperature reading.

This fan is different from others that you normally see, but it is designed for 1U/2U servers.? The fan is a bit noisy, but it can keep the air flowing inside your case.? The wide area the fan covers is good for general cooling.? One thing I was disappointed about is the lack of instructions or mounting hardware, other than that this is a very nice fan that would be a good addition to any case.
