This wide range enables precise adjustment of the fan to the specific requirements of the server, ensuring efficient cooling performance under different operating conditions.\u003c\/p\u003e\u003cp\u003eThe fan is equipped with a standard 4-pin connector, which also allows connection to 2-pin or 3-pin headers. The 30 cm long cable offers additional flexibility in fan placement.\u003c\/p\u003e\u003cp\u003eA 10 °C lower motor temperature roughly doubles the service life. The motor of the S12038-8K is not only particularly efficient, but is also actively cooled by an additional impeller in the fan hub. To ensure a long service life in particularly dusty environments, a sticker to cover the fan hub impeller is included in the packaging.\u003c\/p\u003e\u003cp\u003eThe impeller of the S12038-8K is held by two high-quality Japanese ball bearings in a sturdy brass housing. This design increases the stability, strength and perpendicularity of the fan and minimises sensitivity to influences such as heat and dust. In addition, the brass housing helps to reduce wear on high-speed fans.\u003c\/p\u003e\u003cp\u003eEspecially in server environments, fans with a high pressure are required to enable sufficient air circulation in the often tightly packed enclosures. The S12038-8K fits into server cases from 3U and serves as an upgrade or replacement for a CPU fan, radiator fan or for system ventilation.\u003c\/p\u003e\u003cp\u003eIn addition to server cooling, it is also used in industrial systems and plays an important role in machine control and automation systems. Reliable and robust, it guarantees performance in various hardware environments and ensures efficient cooling and minimised downtimes.\u003c\/p\u003e\u003cp\u003eFor the same performance, the S12038 consumes 22 % less than the next best competitor, improving the energy efficiency of your server. The reduction of the power consumption is the result of months of motor optimization by ARCTIC engineers with the aim to increase the IT equipment efficiency.\u003c\/p\u003e\u003cp\u003e70 °C ambient temperature, high dust exposure and changing humidity - we carry out our long-term tests under these extreme conditions to ensure the service life of our products.\u003c\/p\u003e\u003ch5\u003eSpecifications\u003c\/h5\u003e\u003cp\u003e\u003cstrong\u003eFan\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;margin-bottom:10px;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003eARCTIC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eSize\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e120 × 120 × 38 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eSpeed range\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e800–8000 rpm PWM controlled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eBearing type\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003eDual Ball Bearing with Brass Housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003ePerformance\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;margin-bottom:10px;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eAirflow\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e220 cfm (370 m³\/h)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eStatic pressure\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e37 mmH₂O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eAcoustics \u0026amp;
