I've recently purchased a "fume extractor" from China which is basically a filter with a pc fan behind it. The Fan pre-installed isn't really doing much of anything and I would like to replace it with a powerful PC fan that I have lying around.

I have a multimeter lying around but am not really proficient with it. The diagrams that I can find on the web for PWM fans state that Black should be ground and yellow should be 12v. The pre installed fan only sported 2 wires instead of the 4 of mine and thus isn't anything to go by.

Can I just hook up the ground / 12v wire to the corresponding wires from the "fume extractor" or is there anything else I should be aware of?
