I have the same noctua fan but I bought the 120mm to replace a fan inside a fume extractor. My problem is the fan doesn’t work hooked up directly to the 12v power supply like you did, any suggestions? Thanks btw nice vid
Hmm… I’d check if you’re actually getting 12V from the connectors coming out of the fume extractor. Some aren’t actually built for 12V PC fans. Then I’d just try powering the fan with your own 12V source so you’re sure it’s working properly.
@ I’ve checked it I also connect the fan to my bench power supply same thing no spin, but when I connect it to a pwm fan controller it does work but then it stop
I think the fan is probably bad then. If you just bought it, you should return it. Connecting V+ and GND only to a 3-pin or 4-pin fan should just have it run at full speed with no PWM signal

@ it was the fan, I returned it and bought a new one as you suggest. The new one is working perfectly, thanks man
Cool idea!
