Hi, Does anyone know where I can buy a 3.3V d.c. 40mm x 40mm fan? The fan in my network switch has died. I have looked on Ebay, Element14, RS, local computer stores, Google. The only source I can find is DHgate, minimum qty 100 pcs. 5V and 12V are prolific of course. The switch internal PSU has only 3.3V output. I found replacement 40mm fans for specific Cisco etc switches, but there is no mention of operating voltage. I have tried 5V fans, but they turn so slowly that virtually no air is shifted. The switch gets too hot with no fans. The only other option I can think of is to buy/assemble a 3.3V to 5V dc-dc converter. Cheers,
↧
