Case Fan NoiseBlocker NOISEBLOCK XC1 80 mm, low-noise 21 dB
The NoiseBlocker BlackSilentFan XC1 is an 80 mm case fan designed for PC chassis cooling. With a compact 80 x 80 x 20 mm frame and a rated speed of 1400 RPM, it delivers an airflow of 21 CFM while operating at a low noise level. The fan runs on 12 V nominal voltage and is suitable for standard 80 mm mounts in cases, small radiators or on CPU coolers that accept this size.
The BlackSilentFan XC1 provides a balance of airflow and quiet operation, achieving 21 CFM at a measured noise level around 18 dBA. Its compact 20 mm thickness makes it compatible with tight installation spaces. The fan is certified to common standards (TÜV, ISO 9001, RoHS) and has a low starting voltage of 5 V for reliable startup in systems with limited power. Lightweight construction (60 g) simplifies mounting without adding significant mass.
Install the NoiseBlocker XC1 into any standard 80 mm mounting location in the chassis or on compatible cooling hardware using the appropriate screws or rubber mounts. Connect the fan to a 3-pin or 2-pin 12 V fan header on the motherboard or to a compatible power connector from the power supply, observing correct polarity. For best results, position the fan to establish a consistent airflow path through the case (intake or exhaust) and avoid obstructing the blades during installation.
For quiet operation, connect the fan to a motherboard fan header with speed control where available and set a modest fan curve. Periodically check and clean dust buildup on the fan blades and grille to maintain airflow and noise characteristics; operating temperature range is -10 °C to 65 °C.
