SXDOOL NMB 3115RL-04W-B96 80mm PWM Fan
This 80mm case fan uses a double-ball bearing and a 4-pin PWM connector for motherboard speed control. It runs on 12V power with a 3A rating and reaches speeds above 7000 RPM. The black, non-LED frame measures 80 by 80 by 38mm with a 31cm lead.
Suited for tight builds needing high airflow at 12V
Builders fitting an 80mm mount with a 4-pin header can use the wide 1000 to 8500 RPM range for targeted cooling. The 3A draw demands a header or controller rated for that current. It is not for systems limited to lower-amperage fan headers, silent-priority builds, or cases that only accept 25mm or thinner fans.
Double-ball bearing rated for 180000 hours
The bearing type is the key durability spec; double-ball construction targets long service life in continuous operation. PWM control allows the motherboard to adjust speed between the stated minimum and maximum. Verify that your board’s 4-pin header can supply 3A before installing.

Questions about this item
How do I install the 80mm 12V PWM fan and which step do people often get wrong?
Mount the 80×80×38mm frame with four screws, connect the 4-pin 2510 connector to the motherboard PWM header, and route the 31cm cable; the step most often missed is plugging into the PWM header instead of a 3-pin voltage header, which disables speed control.
What maintenance or replacement will the double ball bearing fan need later?
The double ball bearing is rated for 180000 hours; no lubrication is required, but expect eventual bearing wear — plan to replace the entire fan once noise or vibration appears after that service interval.
What limit appears first during sustained high-speed operation?
At speeds above 7000 RPM up to the 8500 RPM maximum the 3A current draw becomes the limiting factor — ensure the motherboard header or fan controller can supply 12V at 3A continuously or the fan will throttle or shut down.
