When you finish reflow or hot air work on a motherboard, the board stays hot enough to damage components if you rush the next step, and the 2UUL DA98 Aiolos Fan solves that exact bottleneck on your repair bench. You get a 3-in-1 tool that cools, extracts smoke, and lights your work area from a single compact housing measuring 11011038mm, so it sits comfortably next to your hot air station without eating up bench space. The cooling function pulls board temperature down in around 3 seconds, which matters when you handle back-to-back CPU reballing or PMIC change jobs and can't afford to wait for a board to cool naturally before probing or reassembling. During soldering and desoldering work, the fan's smoke extraction pulls fumes through a replaceable activated carbon filter, keeping flux smoke away from your face while you work close to the board under the microscope. The 360° rotatable head lets you angle airflow or light exactly where you need it, whether you're cooling a specific IC pad after a jumper repair or lighting a dark corner of the board while you trace a hardware fault. Power comes from a built-in 3.7V 1200mAh battery that charges over standard USB, so you're not tethered to a wall outlet mid-repair, and you carry it between workstations or take it into the field for on-site service calls. Controls stay simple: one button handles shutdown, a two-gear timer lets you set how long the fan runs so you don't have to babysit it during longer cooling cycles, and three-gear speed control adjusts airflow intensity depending on whether you're doing light board cleaning or aggressive post-rework cooling. A four-speed power display keeps you aware of remaining battery life, so you're not caught mid-reballing session with a dead fan. The motor spins up to 6500r/min at full speed, giving you enough airflow to handle motherboard-level cooling and fume clearing without the bulk of a full workshop extraction system. At 340g and shipping in compact 13114063mm packaging, it's light enough to move around your bench or store in a toolbox drawer between jobs. This kind of tool earns its place in the workflow between hot air rework and board reassembly, right where technicians typically wait around doing nothing productive while a board cools on its own. Whether you're changing a charging IC after a "dead after flash" case, reballing a CPU on a board that came in with a boot loop issue, or doing routine board cleaning before a final diagnostic pass, having dedicated cooling and smoke extraction on hand speeds up the bench rather than slowing it down. Technicians running IC change work, jumper repairs, or extended soldering sessions benefit from having lighting built into the same unit, since it removes the need to reach for a separate lamp every time you reposition the board. The wireless design means you're not managing another power cable across a bench that's already crowded with a soldering station, hot air gun, and power supply. For repair shops and service centers processing high volumes of board-level jobs daily, tools like the Aiolos Fan reduce dead time between repair steps and support cleaner air quality on a workshop floor where soldering and rework happen continuously throughout the day.
