SXDOOL DYTB0838B2U 12V 2.1A 80x38mm 4-pin PWM case fan

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.
