Compact 80 mm PWM fan for high-airflow builds
The SXDOOL DYTB0838B2U is an 80 mm by 38 mm case fan designed for systems that need concentrated airflow in tight spaces. Its 4‑pin PWM connector allows the motherboard to regulate speed automatically. The unit suits compact workstations, industrial enclosures or mining rigs where a slim 80 mm footprint is required.
Dual-ball bearing runs at 10 000 RPM
Dual ball bearings support a rated speed of 10 000 RPM while keeping friction low over long duty cycles. Rated current sits at 1.25 A and peak current reaches 2.1 A at 12 V, so the fan draws noticeable power when spun up. Expect audible airflow noise at maximum RPM; PWM control lets you lower speed for quieter operation when full flow is not needed.
Black non‑LED frame fits standard 80 mm mounts
The all‑black plastic frame carries no lighting, keeping the look neutral for professional or embedded installations. Four mounting holes match the common 80 mm pattern, so the fan drops into existing brackets without adapters. The 4‑pin header supplies both power and speed feedback, enabling closed‑loop control from any standard PWM header.

Questions about this item
How do I install the 80 mm 4-pin PWM fan in a standard case mount?
Align the 80 mm screw holes with the chassis or radiator, secure with four screws, then plug the 4-pin PWM connector into the motherboard or controller header so the board can regulate speed.
What maintenance will the dual ball bearing need over time?
The dual ball bearing is sealed and requires no lubrication; if noise or vibration appears after extended running at 10000 RPM, replace the fan unit.
At what point does the 2.1 A current draw become the limiting factor during sustained operation?
Continuous running at 10000 RPM draws the full 2.1 A, so the power header or supply must sustain that current without voltage droop or thermal throttling.
