Comprehensively solve the start-up problem of the first-generation pseudo-speed device that is not compatible with some machines. Batches of Green Magic and Red Magic fan speed controller in-line version and cable version PWM frequency conversion silent fan speed simulator compatible with Ant, Shenma, Xindong and other machines. Change to water-cooled, change to ant silencer, change to oil-cooled and air-cooled must, fully simulate 2250-6500 speed, four-wire, support machine PWM automatic speed adjustment, compatible with 99.99% of the machines on the market, 7*24*365 days of annual power consumption Less than 50 cents, completely silent, save tens of yuan a year compared to a small fan speed controller Capacitors, resistors, three ji tubes and single-chip microcomputers are all imported products. In order to stabilize the cost, we also customize export-quality plug-in terminals Compatible with S7, S9, S9K, S9J, S9I, S17, T15, T9, T9+, S9i, Z9 MINI, Z9, DR3 and other machines are fully compatible, compatible with M1, M3, all-in-one machines, etc., in theory, as long as the fan can be identified, The green magic speed device can be recognized normally. Note: Most new machines need 2 fans (for example: S9, T9+, V9), so buy two at a time. In addition, the pseudo-speeder only fooled the machine, saying that it has a fan, and the heat dissipation of the machine still needs other ways, such as water-cooled oil-cooled air-cooled, centrifugal fan. . .
